Definitions
Client: A computer or device that makes use of a server. As an example, the client might request a particular file from the server.
DHCP: Dynamic Host Configuration Protocol. In this procedure the network server or router takes note of a client’s MAC address and
assigns an IP address to allow the client to communicate with other devices on the network.
DNS Server: A DNS (Domain Name System) server translates domain names (ie: www.vikingelectronics.com) into an IP address.
Ethernet: Ethernet is the most commonly used LAN technology. An Ethernet Local Area Network typically uses twisted pair wires to
achieve transmission speeds up to 1Gbps.
Host: A computer or device connected to a network.
Host Name: A host name is a label assigned to a device connected to a computer network that is used to identify the device in various
forms of network communication.
Hosts File: A file stored in a computer that lists host names and their corresponding IP addresses with the purpose of mapping addresses
to hosts or vice versa.
Internet: A worldwide system of computer networks running on IP protocol which can be accessed by individual computers or networks.
IP: Internet Protocol is the set of communications conventions that govern the way computers communicate on networks and on the In-
ternet.
IP Address: This is the address that uniquely identifies a host on a network.
LAN: Local Area Network. A LAN is a network connecting computers and other devices within an office or building.
Lease: The amount of time a DHCP server reserves an address it has assigned. If the address isn’t used by the host for a period of
time, the lease can expire and the address can be assigned to another host.
MAC Address: MAC stands for Media Access Control. A MAC address, also called a hardware address or physical address, is a unique
address assigned to a device at the factory. It resides in the device’s memory and is used by routers to send network traffic to the correct
IP address. You can find the MAC address of your K-1770-IP phone printed on a white label on the top surface of the PoE LAN port.
Router: A device that forwards data from one network to another. In order to send information to the right location, routers look at IP Ad-
dress, MAC Address and Subnet Mask.
RTP: Real-Time Transport Protocol is an Internet protocol standard that specifies a way for programs to manage the real-time transmission
of multimedia data over either unicast or multicast network services.
Server: A computer or device that fulfills requests from a client. This could involve the server sending a particular file requested by the
client.
Session Initiation Protocol (SIP): Is a signaling communications protocol, widely used for controlling multimedia communication sessions
such as voice and video calls over Internet Protocol (IP) networks. The protocol defines the messages that are sent between endpoints,
which govern establishment, termination and other essential elements of a call.
Static IP Address: A static IP Address has been assigned manually and is permanent until it is manually removed. It is not subject to the
Lease limitations of a Dynamic IP Address assigned by the DHCP Server. The default static IP Address is: 192.168.154.1
Subnet: A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices
whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100. would be part of the
same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet
mask.
TCP/IP: Transmission Control Protocol/Internet Protocol is the suite of communications protocols used to connect hosts on the Internet.
TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the
Internet, making it the de facto standard for transmitting data over networks.
TISP: Telephone Internet Service Provider
WAN: Wide Area Network. A WAN is a network comprising a large geographical area like a state or country. The largest WAN is the In-
ternet.
Wireless Access Point (AP): A device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. The
AP usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself.
Wireless Repeater (Wireless Range Extender): takes an existing signal from a wireless router or access point and rebroadcasts it to
create a second network. When two or more hosts have to be connected with one another over the IEEE 802.11 protocol and the distance
is too long for a direct connection to be established, a wireless repeater is used to bridge the gap.

The front panel of the K-1770-IP is mounted using security Torx screws to help prevent intruders from removing the panel
and accessing the on board door strike/gate control relays. For applications requiring additional security, a Viking model
RC-4A remote relay controller can be used. The relay controller is mounted securely inside the building and connected to
the same LAN as the K-1770-IP. The on board door strike relays would not be used in this case as the K-1700-IP will send
an encrypted message to the RC-4A to activate its relays which control the door strikes/gates.
Up to 4 K-1770-IP’s can communicate with one RC-4A allowing you to securely control four entrances.
When using an RC-4A for remote relay control the K-1770-IP’s relays should be set to “External” in the PC programming.
Note: If the K-1770-IP loses communications with the RC-4A, the LED on the front panel of the K-1770-IP will flash 3 times
every 2 seconds indicating the communication error. If this error occurs, make sure the RC-4A is powered, has a network
connection and has the correct IP address and security code of the K-1770-IP displaying errors.

The Speed Dial Number is the 1 to 3 digit number visitors enter on the K-1770-IP’s keypad for the unit to call the tenant.
3 seconds after the 1 to 3 digit number is entered, the unit will then dial the Primary Phone Number associated with that
Speed Dial Number. If there is no answer or a busy signal is detected, the K-1770-IP will then dial the Roll Over Phone
Number.
The Primary Phone Number programmed in Index 0 is the number that is dialed when the ”CALL” button is pressed
with no additional digits (if “Call Button Autodial” is enabled). A second Roll Over Number will be dialed when there is
no answer or a busy signal is detected. The K-1770-IP phone is factory set with no Primary or Roll Over numbers
programmed.
Note: Typical Apartment Applications use the tenant’s 1 to 3 digit apartment number as the Speed Dial Number. After
the apartment number is entered the unit will then dial the tenant’s phone number.

3. Event Log
The Event Log button is used to open the Event Log screen. The Event Log screen shows you the time and date of
each event, the event type, relay action (which door/gate was opened or closed), entry code index and phone number
index with tenant name. The Event Log can store up to 4,095 events. Events are stored in a first in first out format.
When the memory is full, new events will over write the oldest events. The Event log can be saved in one of two file
formats: Tab Delimited Text or Comma Separated Variable.

4. Entry Code Database
Clicking on the “Entry Code Database” button will open the Entry Code Database screen.
The Entry Code Database will then download, this can take over a minute. The Entry Code Database will allow you to
program the Relay Function, Relay 1 or 2, once only (one time use only), Entry Type (Card, Keyless or both), Keyless
Code, Proximity Card #, Facility Code, Day of week, Time of Day and Tenant Name. Tenant names are stored locally
on the PC and are not uploaded.
5. Phone Name
6. Mute Alarm Until Next Failure
7. Phone Firmware
8. IP Firmware
Up to a 32 character phone name can be assigned to the K-1770-IP being programmed. Often times the building name
and entrance location near the unit are used for the name.
A network failure alarm will be indicated by flashing the “Call” LED on the front panel and the speaker outputting 3 beeps
every 30 seconds. A network failure indicates the unit is not registered to the SIP server or there is a communication
failure with the gateway. The three beeps can be muted by clicking on the “Mute Alarm Until Next Failure”.
If new K-1700-IP firmware is available, after opening the programming software a pop window will come up asking you
if you would like to update firmware. An alternative method of updating can be done by clicking the phone firmware “Up-
date” button. You can then browse to the folder that contains the HEX file for updating the unit’s firmware. This method
is typically only used when Viking Technical Support has sent you updated firmware.
If new K-1770-IP firmware is available, after opening the programming software a pop window will come up asking you
if you would like to update firmware. An alternative method of updating can be done by clicking the IP firmware “Update”
button. You can then browse to the folder that contains the PIP file for updating the unit’s IP firmware. This method is
typically only used when Viking Technical Support has sent you updated IP firmware

9. Import/Export
The Import/Export feature is useful for backing up all the K-1770-IP’s programming or for importing programming when
installing multiple units with a majority of the same programming.
Clicking on the “Factory Default ” button in programming will reset all of the Programming Features back to their factory
default settings. Note: This command will not change or reset your IP settings.
10. Factory Default
The security code allows the user/installer to program the K-1770-IP phone. The factory set security code is 845464.
It is recommended that the factory set security code be changed.
Note: The security code must be 6 digits and cannot include a
Q or a #.
12. Security Code
11. Diagnostics
The Diagnostics section in the K-1700-IP PC Programming can be used to test the functionality of the mic, speaker,
proximity card reader, and relays.
The Access Code is used for remotely operating the relays (Doorstrike, Mag-Lock, etc) by calling into the unit. This
code provides basic security and only allows operation of the relays and not the ability to change any of the programming
parameters. Once entered, any of the “Remote Access Operation Commands” can be used. The code can be 1 to 6
digits in length and cannot contain a “Q” or “#”. Simply call the K-1770-IP phone, the unit will automatically answer the
line and output one beep. You then enter the programmed 1 to 6 digit access code, 2 beeps should be heard. You can
now enter any “Remote Access Operation Commands” (see page 19).
13. Access Code
The Auto Answer/Loud Ring feature can be set to one of four modes:
Disabled: In the “Disabled” mode the phone will not automatically answer an incoming call.
Auto Answer (factory setting): In the “Auto Answer” mode the phone will automatically answer an incoming call on the
first ring.
Loud Ring: In the “Loud Ring” mode the phone will not automatically answer an incoming call but will output a loud
ring signal out of the speaker in a 2 seconds on, 4 seconds off ring pattern. The call can then be answered by momen-
tarily pressing the call button.
Loud Ring with AGC: In the “Loud Ring with AGC” mode the phone will not automatically answer an incoming call but
will output a loud ring signal out of the speaker in a 2 seconds on, 4 seconds off ring pattern. The phone will automatically
increase or decrease the ring volume based on background ambient noise. The call can then be answered by momen-
tarily pressing the call button.
14. Auto Answer / Loud Ring
15. Ring Cadence
16. Loud Ring Volume
The Loud Ring Volume can be set from 0 – 9. 1 = the lowest volume, 9 = the highest volume and 0 = disabled.
When “Auto Answer/Ring” on the K-1770-IP is set to “Loud Ring” or “Loud Ring with AGC” the Loud Ring cadence can
be programmed to one of 4 different cadences:
Normal Ring (single ring, 2 sec on 4 sec off)
Double Ring (double ring, 1 sec on .5 sec off 1 sec on 3.5 sec off)
Short-Short-Long (triple ring, .5 sec on .5 sec off .5 sec on .5 sec off 1 sec on 3 sec off)
Short-Long-Short (triple ring, .5 sec on .5 sec off 1 sec on .5 sec off .5 sec on 3 sec off)

15
18. Call Button Delay
19. Call Button Auto Dial
The Call Button Delay is the length of time from when the Call button is pressed to when the unit starts dialing the
Primary number programmed in Phone Number Database Index 0. The time is programmable from 0 to 6 seconds.
Adding Call Button Delay time is useful to allow visitors time after they have pressed the Call button to then enter the
tenant’s apartment number (Speed Dial Number) or their Keyless Entry Code.
The Call Button Auto Dial feature allows visitors that do not know the tenant’s apartment number (Speed Dial Number)
a way of simply pressing the Call button with no additional numbers entered. After the Call Button Delay the unit will
automatically dial the Primary Phone Number stored in Phone Number Database Index 0. This could route the call to
the building manager, care taker, receptionist, etc.
Keyless Entry Code and Proximity Card logging can be set to Log Errors. With Log Errors selected, the K-1770-IP will
not only log all valid Keyless Entry Code and Proximity Card entries, but also log any errors, incorrect codes, or non-
valid card reads.
Keyless Entry Code and Proximity Card logging can also be set to Live Logging. With Live logging selected and the
K-1700-IP programming software open and connected to a unit, each Keyless Entry Code entered or Proximity Card
read will immediately open the Event Log screen and display the latest entry.
When using date and time logged events or setting the access date and times of keyless codes or proximity cards in
the Entry Code Database, you must program the unit to your time zone. Example: You are installing the K-1770-IP in
the Central standard time zone: Select (UTC - 06:00) CST, which is 6 hours behind Coordinated Universal Time (UTC).
20. Select Time Zone
The Daylight Saving Time programming can be enabled or disabled and can be programmed to start on any Sunday in
March and stopped on any Sunday in November. Currently, daylight saving time starts on the second Sunday in March
and ends on the first Sunday in November, with the time changes taking place at 2:00AM local time.
21. Daylight Savings
22. Keyless/Card Logging
17. Phone Mode
The Phone Mode can be programmed to one of two settings: Auto Dialer or Manual Dial Phone. When set to Auto Dialer
the K-1700-IP will auto dial any preprogrammed phone numbers stored in the Phone Number Database when the cor-
responding Speed Dial Number (example: apartment number) is entered on the unit’s keypad. When set to Manual Dial
Phone the unit’s auto dialing features are disabled and the unit functions as a standard VoIP speaker phone. Pressing
the call button will take the phone off hook allowing you to manually dial the phone number on the keypad.

16
The one or two digit code stored in the Relay Activation Command is the touch tone command that the person being
called must enter on their phone in order to actuate relay 1 or 2 to control a doorstrike, mag-lock, gate controller, or
other device. The code can contain the numbers 0 - 9, 00 - 99, ## or QQ. The code cannot match a relay latching or
toggle command (11, 10, 1#, 21, 20, or 2#). The code must be entered while the remote phone is communicating with
the Entry phone. The Entry phone determines which direction the touch tone is coming from and only responds to
touch tones from the called phone.
24. Relay 1 or 2 (Activation) Command
The value stored in the Relay 1 or 2 Activation Time is the amount of time relay 1 or 2 will be energized after a correct
touch tone command is entered. This number can range from 0.5 to 99 seconds. The factory setting is 5 seconds.
25. Relay 1 or 2 Activation Time
Doorstrike Mode: When programmed for Doorstrike Mode the relay will momentarily activate for the preprogrammed
relay activation time after detecting the correct relay activation command (one or two digit touch tone) from the called
party.
Outbound Call Mode: When programmed for Outbound Call Mode the relay will activate continuously for the duration
of any outbound call from the Entry phone.
Inbound/Outbound Call Mode: When programmed for Inbound/Outbound Call Mode the relay will activate continu-
ously for the duration of any inbound or outbound call to or from the Entry phone. This mode is useful for turning on IR
flood lights, for VoIP phones with cameras, etc.
Doorbell Mode: When programmed for Doorbell Mode the relay will momentarily activate the relay for the prepro-
grammed relay activation time on any outbound call from the Entry phone. This mode is useful for activating a door
chime, etc. When activating door chimes, a 0.5 - 1 second relay activation time is recommended.
Alarm Mode: When programmed in Alarm Mode the relay will activate continuously while the Entry phone is powered
and registered to the SIP server. In the event the unit loses power and/or SIP registration the relay will turn off, which
can be used to signal an alarm device.
Loud Ring Mode: When programmed for Loud Ring Mode the relay will continuously activate while the ringing exten-
sion is called. This mode is useful for activating a Viking model SL-2 strobe light, etc.
Loud Ring Flash Mode: When programmed for Loud Ring Flash Mode the relay will momentarily turn on and off in
a 400ms on/off cadence while the ringing extension is called. This mode is useful for activating a Viking LPL-1 Remote
Visual Indicator, etc.
23. Relay Mode
26. Relay 1 or 2 Internal / External
With relay 1 and/or 2 set to “Internal” the K-1770-IP will activate its on board relays for doorstrike / gate control. Relay
1 and/or 2 should be set to “External” for higher security installations when using a Viking model RC-4A remote relay
controller to activate the doorstrike / gate controller (see page 6).
27. Relay Activation Delay
A relay activation delay of 0.5 to 99 seconds can be programmed in the K-1770-IP. A relay activation delay is useful in
two door vestibule entrance applications. This allows you to program a delay time from when relay 1 (outside door) is
activated to when relay 2 (inside door) is activated. The programmed delay time should be set to the average time it
takes a person to walk from the outside door to the inside door.
When a request for exit (REX) is activated, relay 2 will activate first, then after the programmed delay relay 1 will
activate.

17
The Speaker Mode can be set to one of the following two modes.
OFF/Silent Monitoring Mode: In the “OFF” mode the speaker is disabled on inbound calls. However, the speaker
can be enabled after communication has been established by entering touch tone command “9#”. The speaker will
then remain on for the duration of the call.
ON (factory setting): In the “ON” mode the speaker is enabled during In-bound and Out-bound calls.
30. Speaker Mode
When programmed to “Enable” (factory default) the Remote Access Operation Commands to Un-Latch or Latch the
relay are enabled.
When programmed to “Disable” the Remote Access Operation Commands to Un-Latch or Latch the relay are disabled.
Disabling the Latch commands can be useful in applications where you want to eliminate the possibility of inadvertently
entering a latch command leaving a gate open/closed, etc.
29. Latch Commands (Enable / Disable Relay Latching Commands)
The speaker volume can be set from 0 to 9 (0 = lowest volume setting, 9 = the highest, factory set to 2). Alternatively
the speaker can be turned off for silent monitoring (see Speaker Mode section 30).
31. Speaker Volume
The microphone volume can be set from 1 to 9 (1 = lowest volume setting, 9 = the highest, factory set to 5). Alternatively
the microphone can be placed in the “ANC” Automatic Noise Cancelling mode. With the mic in the ANC mode, when
background noise increases, the mic gain will automatically decrease. When background noise decreases the mic gain
will automatically increase. The ANC mode is useful in applications where the background noise level can change dras-
tically such as a gas car running vs a diesel truck.
32. Microphone Volume / Automatic Noise Cancelling Mode
This feature selects switching time between talk and listen modes (VOX switching time). The Talk/Listen Delay can be
programmed from .1 to .9 seconds.
Note: The factory default is .5 seconds.
33. Talk / Listen Delay (VOX)
The In-Band Audio Call Progress Detection can be set to enabled or disabled. In-Band Audio Call Progress detection
should be enabled in applications where you are making an outbound call through your VoIP phone system and are
relying on In-Band analog audio for ringback or busy detection. The factory default is: enabled.
34. Audio Call Progress (In-Band Audio Call Progress Detection)
The In-Band Audio Detection level (Sensitivity) can be set from 1 to 9 (1 = minimum setting, 9 = the highest, factory set
to 5). Increasing or decreasing the sensitivity may be required in applications where you are making an outbound call
through your VoIP phone system and are relying on In-Band analog audio detection.
35. Audio Detect Level (In-Band Audio Detection Level / Sensitivity)
The relay activation tone is a buzzing sound that is heard at the Entry phone when the door strike relay is activated.
After the called party enters the correct relay activation command, the called party will hear 2 short confirmation beeps
and the entry phone will output a buzzing sound (relay activation tone) while the door strike relay is activated. The tone
(buzz) length will match the relay activation time up to a maximum of 5 seconds. The tone (buzz) can be programmed
to three different volume settings 1 = Low, 2 = Medium, 3 = High or it can be disabled.
28. Relay Buzz (Activation Tone) Volume

18
If enabled and a busy is detected, the K-1770-IP phone will dial the “Roll Over” speed dial number. Notes: This feature
is enabled in the factory default setting. If the busy signal is interrupted with a promotional message, contact your
central office to have it removed.
38. Dial Next # on Busy
39. Live Dialing Format
40. REX Input
The Live Dialing Format can be set to In-Band DTMF (Touch Tones) or RFC 2833 (Out of Band DTMF Touch Tones). Live
dialing refers to the numbers dialed after an outbound call has been answered by the distant party. This would typically be
the numbers dialed to steer through automated attendants, voice mail, etc. If your VoIP phone system does not automat-
ically convert out of band DTMF to In-Band after the call is answered, set Live Dialing Format to “Inband DTMF”.
The K-1770-IP has one Request for Exit (REX) trigger input. The REX switch must have a momentary, normally open
contact. When the K-1770-IP detects a contact closure on the REX trigger input it performs one of the following actions,
based on the Relay Mode settings (see section 23):
Relay 1 "Door Strike", relay 2 other: Relay 1 will be activated for the programmed Relay 1 Activation Time.
Relay 1 other, relay 2 "Door Strike": Relay 2 will be activated for the programmed Relay 2 Activation Time.
Relay 1 "Door Strike", relay 2 "Door Strike": Relay 2 will be activated for the programmed Relay 2 Activation Time,
then after the Relay Activation Delay time has passed, relay 1 will be activated for the programmed Relay 1 Activation
Time. This is useful in two door vestibule applications where relay 1 is used to unlock the outside door, and relay 2 is
used to unlock the inside door.
Operation
A. “CALL” Button
With the call button Auto Dial Delay set to No Delay (factory default), when the “CALL” button is pressed, the K-1700-IP
immediately dials the pre-programmed telephone number stored in the Phone Number Database Index location 0. With
the call button Auto Dial Delay set from 1 - 6, when the “CALL” button is pressed you will hear 1 - 6 seconds of dial
tone, allowing you time to enter the 1-3 digit Speed Dial number. The unit will then dial the Phone Number Database
Index location 0-250 associated with the preprogrammed 1-3 digit Speed Dial Number (0-999). The Call Status LED
momentarily flashes during dialing. In the event the line is busy or there is a ring-no-answer, the unit can be programmed
to call a second roll over number.
When the call is answered, relay activation commands can be entered or the # key can be used to force the phone to
hang-up.
After communication is established, enter the 1 or 2 digit relay activation command (factory set to “QQ”for Relay 1 and
”Q2” for Relay 2) to momentarily activate the entry phone (door strike) relay. Two beeps will be heard confirming that the
relay has been activated. If you require the relay to remain on continuously (ie: a truck delivery), enter Touch Tones “11”
or “21” to continuously activate relay 1 or relay 2 respectively. A double beep will indicate that the relay is latched on.
When the visitor calls in again (ie: they are finished unloading the truck), enter Touch Tones “10” or “20” to deactivate
relay 1 or relay 2 respectively. A single beep will indicate the relay is latched off.
37. Dial Next # on RNA (Ring No Answer)
If enabled and a ring-no-answer is detected, the K-1770-IP phone will dial the “Roll Over” speed dial number.
Note: Factory set to redial if not answered after 7 rings.
This feature selects the maximum length of time that calls can be connected. Programmable in increments of 1 minute
up to a maximum of 9 minutes or disabled. With the call length disabled, the K-1770-IP phone must rely on a call
ended signal, busy signal, silence or return to dial tone to hang-up.
Note: The factory default is 3 minutes.

Troubleshooting
If the unit cannot register with the programmed SIP server, the LED will blink on and off every two seconds, and three error
beeps will be heard every 30 seconds until communication is restored. This alerts a potential user of a problem with the
device that will prevent an emergency phone call from being made.
You may silence the error beeps, per instance, by pressing and holding the CALL button for 5 seconds or by clicking the
“Mute Alarm Until Next Failure” button in the Viking K-1700-IP Programming Software (see section Aon page 7). The error
beeps automatically re-enable once the unit is registered, to alert of any new problems that arise.
C. Keyless Entry Codes and One Time Use Keyless Entry Codes
D. Proximity Cards
Keyless entry codes may be used by the tenants to provide keyless entry. The K-1770-IP can be programmed with a combination of up
to 1000* keyless entry codes or one time use keyless entry codes. The keyless entry codes can be programmed to be from 1 to 6 digits
in length. Each keyless entry code can be programmed to activate relay 1 and/or 2 in four different relay modes: Momentary, Latch, Un-
Latch and Toggle. To use a keyless entry code the tenant simply dials “#” followed by the entry code on the K-1700-IP’s keypad. After
the one time use keyless entry code has been used, it is instantly cleared from the unit’s memory. This is ideal for issuing keyless entry
codes to service personnel, etc.
Note: A short buzz sound indicates when the relay has been activated and the visitor can now open the door.
Proximity cards can also be used by the tenants to provide keyless entry. The K-1700-IP can be programmed with up to 1000* proximity
card numbers. Each proximity card number can be programmed to activate relay 1 and/or 2 in four different relay modes: Momentary,
Latch, Un-Latch and Toggle. To use a proximity card the tenant simply presents a preprogrammed proximity card within 6 inches of the
proximity card reader attached to the K-1770-IP. A short beep will be heard from the card reader indicating a card scan. If the card matches
a valid preprogrammed card number a short buzz sound will be heard indicating the relay has been activated and the visitor can now
open the door or gate.
B. Remote Access Operation Commands
The following commands can be entered after answering an inbound call from the entry phone. The commands can also be entered
on an outbound call to the entry phone. After the entry phone auto answers the call, one or two beeps will be heard. If the access
code has been disabled (two beeps heard), you can now enter the Remote Access Operation Commands below. If an Access code
has been programmed (one beep heard), enter the Access code digits. With the correct code entered, two beeps will be heard and
you can now enter the Remote Access Operation Commands below. The relay must be set to “Door Strike” Mode to be controlled by
these commands.
*Note: 1000 is the total number of Keyless Entry Codes and/or Proximity Card numbers that can be programmed in the Entry Code Database.
