Introduction1
Fig. 1. The DAC-P
The DPS Telecom DAC-P serves as a mediator between remote telemetry units and the DPS Telecom Network Telemetry
Processor (NTP). The DAC-P collects alarm reports from remotes, maps remote data to a MEFA display grid, and forwards
the data through a four-port TABS responder to the NTP.
The DAC-P communicates with remotes through four dial-up modem lines. Either the DAC-P or one of its remotes can
initiate a dial-up connection. All four modem connections can be used simultaneously.
The DAC-P also provides central control for alarm collection remotes. The DAC-P manages dial-up connections, provisions
remotes with configuration data, provides extensive monitor visibility to help diagnose problems, and forwards control relay
and reboot commands from the NTP to remotes.
These control functions, plus alarm monitoring, are accessible remotely over a LAN/WAN connection or locally through a
craft port connection.
The DAC-P channels are provisioned via FTP with a configuration file derived from the TMAS database. Other
configuration options are set locally through a craft port or Telnet connection. For more information, see Section 6,
"Configuration."
This User Manual contains all the information you need to successfully install and configure the DAC-P. However, if you
run into a problem or require additional help, DPS Telecom's courteous Technical Support staff is ready to provide the
assistance you need.

Operation4
The DAC-P communicates with its alarm collection remotes through dial-up connection. The DAC-P has four DB9 RS-232
serial ports for connecting to up to four modems and four phone lines. The dial-up connection between the DAC-P and its
remotes is two-way; either the DAC-P can initiate a call to poll a remote, or a remote can initiate a call to report an alarm.
The remote will call the DAC-P if:
• Any alarm occurs. (All alarm events are considered equally severe.)
The DAC-P will call the remote if:
• The alive/full update time expires without a call from the remote. The default alive/full update time is 24 hours. The DAC-
P will reset the alive/full update clock if the remote calls to report an alarm.
• The DAC-P receives a control relay command for the remote unit.
• The DAC-P receives a dial command for the remote unit.
• The DAC-P receives a reboot command for the remote unit.
• A DAC-P user chooses the Dial RTU or Reboot RTU command from the terminal interface.

Mounting5.2
Fig. 3. The DAC-P can be flush or rear-mounted.
The DAC-P can be mounted in a 19" rack or a 23" rack by using different rack ears for each size. Two rack ear locations are
provided. Attach the appropriate rack ears in the flush-mount or rear-mount locations shown in Figure 3.
Power Connection5.3
To connect the DAC-P to a power source, follow these steps:
1. Remove the fuse from the front panel of the DAC-P and make sure that the power supply to the unit is off.
2. Remove the screw lug barrier plug from the front panel of the DAC-P.
3. Connect a -48 VDC line to the -48V terminal and a battery ground to the GND terminal of the screw lug. Seat the barrier
screws firmly, but be careful not to nick the bare wire. Repeat for power source B if you have dual power inputs.
4. Push the plug firmly back into its socket. Note that this connection is keyed and the plug must be properly aligned within
the socket.
5. For earth/frame grounding, connect a copper wire with a ring terminal to the grounding post located on the back panel of
the DAC-P. DPS Telecom recommends wire of at least 14 gauge. Place the ring terminal between the two nuts and secure the
nuts on the grounding post. Connect the other end of the wire to an earth/frame ground.
6. With the DAC-P fuse still removed, turn on the power supply.
7. Connect the black common lead of a voltmeter to the GND terminal and the red lead to the –48V terminal. The voltmete
r
should read between –43 and –53 VDC. If the reading is outside this range, check your power supply.
8. Do not power the unit until all connections have been made.
9. Insert the fuse to power the DAC-P.

Configuration6
Craft Port6.1
Fig. 7. The DAC-P craft por
t
The DAC-P can be provisioned and configured either locally, through a craft port connection, or remotely, through a
LAN/WAN connection. However, some initial configuration must be done locally before you can access the DAC-P through
a network connection.
To make a local connection to the DAC-P, connect a DB9 serial cable from the COM port of your computer to the craft por
t
on the front panel of the DAC-P.
Fig. 8. Port settings to connect to the DAC-P
Select the following COM port options, as shown in Figure 8:
• Bits per second: 9600
• Data bits: 8

9
• Parity: None
• Stop bits: 1
• Flow control: None
Terminal Interface6.2
Fig. 9. DAC-P configuration main menu
When you first connect to the DAC-P, all you will see on your screen is a cursor. The Quiet logon feature, which suppresses
the password prompt and the asterisks normally seen when typing passwords, is enabled by default. If you would like to see
a password prompt when connecting to the DAC-P, disable the Quiet logon feature. For instructions on disabling Quiet
logon, see Section 6.6.1, "Logon."
You must enter the password to continue. The factory default password is "dpstelecom," all in lower case. You can change
the password later. Type the password (no asterisks will be displayed if Quiet logon is enabled) and press Enter.
After entering the password, you will see the DAC-P configuration main menu, as shown in Figure 8.
To choose a command, press the key for the letter before or within the parenthesis. For example, to select the C)onfig menu
from the main menu, press C. To e(X)it the terminal interface, press X.
To quit a menu, press Esc, and you will return to the previous menu.
For configuration changes to take effect, you must save your changes in the DAC-P's memory. To save changes, press Esc to
return to the main menu. A confirmation prompt will ask if you want to save changes. Alternatively, you can save your
changes by choosing C)onfig > E)dit > n(V)ram > W)rite. (For more information about writing to NVRAM, see Section
6.6.6, "NVRAM."
N
ote: If you are using a Unix Telnet client to access the DAC-P, make sure your terminal software is set for character mode.
Many Unix clients are set by default to line mode, which is incompatible with the DAC-P terminal interface. To set your
Telnet client for character mode, press the Esc key to enter command mode and type "mode char." For more information,
consult the man page for your Telnet client.

10
Assigning an IP Address6.3
Fig. 10. Assigning an IP address.
Your first step in configuring the DAC-P is to assign it an IP address, so that the unit will appear on your network. The IP
address must be unique—no other device on the network should have the same address.
Connect your computer to the craft port of the DAC-P and begin a terminal session. (See Section 6.1, "Craft Port," for
instructions.)
Choose C)onfig > E)dit > E)thernet. The screen will display the current IP configuration and a menu for editing IP
configuration. (See Figure 10 above.)
You must assign the DAC-P a unit IP address, a subnet mask, and a default gateway. To edit these fields, choose the
appropriate command from the menu. You will be prompted to type a value, as shown in Figure 9.
After making your selections, you must reboot the unit for the changes to take effect. Choose C)onfig > E)dit > s(Y)stem >
R)eboot > y)es.
To verify the DAC-P's IP configuration, ping the IP address you assigned the unit.

11
Configuration File6.4
Fig. 11. A sample configuration file
The DAC-P must be provisioned with a configuration file that defines the remotes it will poll. The configuration file is a tex
t
file derived from the TMAS database using utility software. The file is transmitted to the DAC-P via File Transfer Protocol
(FTP).
N
ote: Every time a configuration file is uploaded to the DAC-P, the unit's memory is completely overwritten. You mus
t
always upload a complete configuration file. If a section of the configuration file is omitted, the default settings for tha
t
section will be used.
A sample configuration file is shown in Figure 10. The file is divided into two sections: #ADDR_CFG and #PHONE_CFG.

The #ADDR_CFG section defines which remotes the DAC-P will poll, what type of device the remote is, and to which
MEFA to map the device. Valid entries for the address field are 0 to 255. Valid entries for the device type field are: "a" for
DS5000 (single); "b" for DS5000 (dual); and "c" for DS3000 or KDA-E2A. Valid entries for the MEFA field are 0 to 31.
Each line of the #ADDR_CFG section defines an individual remote. Each remote must have a unique address and MEFA.

Fig. 13. Elements of a #PHONE_CFG entry
The #PHONE_CFG section defines the phone numbers associated with remotes. Each line of the #PHONE_CFG section lists
the address of the remote, the type of phone number, and the phone number.
Each remote can have three phone numbers:
1. "o": Outbound phone number. The phone number the DAC-P will dial to call the remote.

12
2. "p": Primary phone number. The first number the remote will call to report an alarm. This phone number will be
downloaded to the remote.
3. "b": Backup phone number. The phone number the remote will call to report an alarm if the primary phone number fails.
This phone number will be downloaded to the remote.
If a type of phone number is not defined, no phone number for that function will be assigned. For example, for these lines of
the #PHONE_CFG section:
A001o1-559-454-8167AURR,AK
A001p1-559-454-1941AURR,AK
A002o1-559-454-8181AURR,AK
N
o line of the configuration file begins "A001b . . .", and therefore the remote at address 1 has an outbound phone numbe
r
and a primary phone number, but no backup number.
The tag "#END_CFG" signals the end of the configuration file. This tag should appear only once, at the end of the file. No
sections should appear below this tag. Do not put this tag between sections.
Uploading the Configuration File6.5
Fig. 14. Uploading the configuration file
The configuration file must be uploaded to the DAC-P via File Transfer Protocol. No username is required, but you mus
t
give a password. The factory default password is "dpstelecom." Any FTP client may be used to transfer the configuration
file, but only a limited set of FTP commands are supported.
To transfer the file from a DOS prompt, follow these steps (see Figure 14 above):
1. From the DOS prompt, change to the directory where the configuration file is located.
2. Type "ftp" and press Enter.
3. At the FTP prompt, type "Open" and the IP address of the DAC-P, and press Enter.
4. Type the password (factory default is "dpstelecom") and press Enter.
5. Type "put" and the name of the configuration file and press Enter. (If thve configuration file is in a different directory you
must type the full path name.
6. Type "close" and; press Enter to close the connection to the DAC-P.]

13
7. Type "quit" to exit FTP.
If the configuration file is not correctly formatted, you will see a STOR error message, which will state that the data could
not be stored. If you see a STOR error, verify the formatting of the configuration file and upload again. (For information on
configuration file formatting, see Section 6.4, "Configuration File."
After uploading, the DAC-P must be rebooted for the new configuration to take effect.
There are four ways you can reboot the DAC-P:
1. Type "REBOOT" at the FTP password prompt.
2. In the DAC-P terminal interface, choose C)onfig > E)dit > s(Y)stem > R)eboot. (See Section 6.6.1).
3. Cycle power to the DAC-P unit.
4. Select the Reboot command from the LCD display menu. (See Section 9).
Other Configuration Options6.6
More configuration options are available through the DAC-P's terminal interface. To select these options, start a terminal
session with the DAC-P, either locally through the craft port or remotely via Telnet.
6.6.1 System
Fig. 15. System menu commands
To edit identification information for the DAC-P, choose C)onfig > E)dit > s(Y)stem.
The System menu contains commands for editing the name of the DAC-P unit, its location, and the primary contact person
responsible for the unit.
The C)onfig > E)dit > s(Y)stem > R)eboot command reboots the DAC-P. If you choose the R)eboot command, a
confirmation prompt will ask you to confirm your choice.

14
6.6.2 Logon
Fig. 16. Editing the Master Password
To edit passwords and define security levels for users, choose C)onfig > E)dit > L)ogon.
The first three commands on the Logon menu define options for the Master Password. The Master Password has all access
rights. There is no user name associated with the Master Password.
The options for editing the Master Password are: minimum length of the password, the password itself, and the Quiet logon
option.
If you choose to change the Master Password, you will be prompted to type the new password once to enter and a second
time to confirm. If both entries are the same, the screen will display "Password change successful."
When enabled, Quiet logon disables the password prompt and the asterisks that normally appear when the password is typed.
For increased security, the default setting is Quiet logon Yes. The Q)uiet logon command is a toggle command; pressing the
Q key will switch between Quiet logon Yes and Quiet logon No.

15
Fig. 17. Authorized user lis
t
To set passwords and security levels for users who do not have access to the Master Password, choose C)onfig > E)dit >
L)ogon > A)dvanced.
Up to 16 users can be defined, and each can have unique access rights. In the example in Figure 17, the user MONITOR is
authorized only to access the monitor screens, while the user EDIT can only edit the configuration database. To create or edi
t
a user, type is or her ID number and press Enter.

16
Fig. 18. Editing user security levels.
Once you have selected a user, you can define the user's name, password, and access. If you choose the U)ser or P)assword
commands, you will be prompted to enter the user name or password. User passwords must be entered a second time for
confirmation. If you want to delete a user, choose the U)ser command, erase the user's name, and press Enter. A confirmation
prompt will ask you if you want to delete the user.
Choosing the A)ccess command opens a list defining the user's access privileges, as shown in Figure 18. Choosing one of the
menu commands toggles permission for that item. In the example above, to add database editing access to the user
MONITOR, press D, and the list will update to read "DB Edit: Y." To remove MONITOR's monitoring privileges, press M,
and the list will update to read "Monitor: N."
The S)ecurity command gives the user the privilege to edit passwords, including the Master Password. A user with only DB
Edit privileges cannot edit passwords.
If all access privileges are set to Y, the user has the same access privileges as the Master Password.
