The PC-100 communications interface can be used for a number of different
applications.
PC-100s can be used to interface alarm panels with the AxiomV™ system.
Paradox panels and a couple of DSC panels can be interfaced this way.
Wavetrend long range readers are also interfaced to the AxiomV™ with the PC-
100.

Virtual IOC Emulator
With firmware version VIOC8 the PC-100 is used to emulate IOC-16 controllers.
One PC-100 can emulate from one to sixteen IOC-16 panels. Some alarm
panels (the host) can use this version as a general means to interface with the
Axiom system.
The emulated IOC16s act as inputs to the network and will present the various
states and configurations that a normal IOC16 would do. If configured as an
input, commands sent through the host channel will generate messages into the
Axiom system. If configured as an output, output control messages will be sent
to the host from the Axiom system. A simple protocol has been designed that
allows foreign vendors an opportunity to interface to the Axiom Access Control
System by messages to the RS232 or RS485 port on the PC100.
DIP-Switch Settings
The Axiom Access Control System starts its IOC addresses at address 5 and can
support up to sixteen devices ending at address 20. To make the DIP-switches
capable of selecting the range of addresses to which the emulator will respond,
an offset address scheme has been developed. The first four switches create
the start offset and the last four switches create the end offset. Desired
Address = DIP address + 5. The device when polled will answer any address
that falls between the desired start and end addresses (inclusive). If the end
address is smaller than (or equal to) the start address only the start address will
be used.

Protocol
The protocol is ASCII based C/R delimited with fixed length.
Input Protocol
Whenever the host issues an input command it uses the following protocol. Input
messages start with fixed text „RBH‟ which is followed by the appropriate point
number, followed then by the numeric value for the correct state, and ends with a
C/R (carriage return).
Fixed Text
Point Number
State
Fixed Text
001-256
0 = Restore
1 = Alarm
2 = Trouble
3 = Illegal
C/R

nnn
s
(0x0d)
A change in state will cause an appropriate log message to be transferred to the
Axiom Access Control System. When an input is armed by the Axiom System
only alarm and restore messages are available. Virtual Inputs have all the same
software features as regular inputs. This includes links, operator commands, and
schedules (the only programming that is irrelevant is circuit type).

2. RBH1030 C/R = Input #7 on panel address #11 has restored.
3. OUT1811 C/R = Output #5 on panel address #16 has turned on.
4. OUT0440 C/R = Output #12 on panel address #7 has turned off.
Firmware Upgrade
It is anticipated that the protocol will change according to manufacturer
requirements. A method of upgrading firmware for this purpose is available in
the latest version of Axiom software (Service Pack 5 [5.2.14] 5-Apr-07). By
selecting only one of the emulated IOC16s for a device firmware upgrade the
firmware will be overwritten with a selected RBH file.
It takes approximately two minutes for the upgrade to be completed.
Be sure to use the proper firmware file when upgrading a virtual IOC board.
A regular IOC firmware file will not work in a virtual IOC (and vice versa). If
this does happen the only way to correct the situation will be to replace the
firmware chip.

Paradox Alarm Panel Interface
This interface is designed to work with Digiplex EVO48 and EVO192 Alarm
panels manufactured by Paradox Security Systems. The protocol used for this
interface is the ASCII protocol designed for home automation. In order to use the
protocol an APR-PRT3 module must be installed and programmed into the alarm
panel.
The PC100 is used as a bridge between the Axiom Access Control System and
the APR-PRT3 interface for the Paradox alarm panel. To achieve this
functionality the PC100 emulates eight Safesuite™ keypads and up to eight
sequentially addressed IOC‟s.

Whenever a partition is armed or disarmed by the Paradox system the
corresponding Safesuite™keypad will display the status. For example if keypad
number 102 reports that it is disarmed it really means that Partition 2 has been
disarmed.
For a Simple Set-up
The Safesuite™ keypads have 8 zones assigned to each keypad. Whenever an
alarm message is sent from the alarm panel it gets translated into two messages:
1. A keypad alarm message.
2. An IOC-16 input change message.
The keypad zone alarm message doesn‟t accurately reflect the actual input
address but instead translates the zone number into a modulo –8 value. See
table below.

As long as each area has eight or less nine inputs and every area begins with a
modulo –8 value (1, 9, 17, etc) the Keypad Zone Alarm will reflect the input
number for the area.
For more complex Installations
For installations where there are more than eight zones per partition the virtual
IOC‟s will reflect the input status. Using Links to arm or disarm a group of inputs
allows the virtual IOC‟s the capability of reporting the Paradox panel‟s inputs
correctly. For inputs used for entering and exiting as well as follower style inputs
use an abort delay to prevent an invalid alarm message. Using an input group
assigned to a virtual keypad allows the software the capability of assigning any
number of inputs to each virtual keypad.
To truly reflect the input status of the Paradox alarm panel four links must be
added to the keypad configuration.

IOC Setup
Determine the number of IOC‟s needed to reflect the number of inputs in the
alarm panel. Add these IOC‟s starting from address #5 and make them all
inputs. Inputs that are used for entry and exit should be given an abort delay to
prevent false alarms. A link may be given to the entry zone to disarm the
follower zone when abnormal.

24 February, 2010
RBH Access Technologies Inc. 10 of 26 TB61_PC-100 for AxiomV™
Input Groups
Create input groups by assigning the associated IOC inputs with partitions
There should be three groups of inputs for every partition:
1) Interior zones.
2) Exterior zones.
3) Entry zones.
Axiom Links
Create four links for every partition.
1) Disarm Link –Disarm Interior, Disarm Exterior, Disarm Entry.
2) Home Link –Disarm Interior, Arm Exterior, Disarm Entry.
3) Evening Link –Disarm Interior, Arm Exterior, Arm Entry.
4) Away Link –Arm Interior, Arm Exterior, Arm Entry.
In order to synchronize the Paradox Alarm Panel with the Axiom Access Control
the Paradox inputs are mapped to virtual IOC-16 using the first eight panels on
the point number table above.
For example, Paradox panel input #88 would be mapped to IOC address #10
input #8. This input would be located in one of eight partitions in the Paradox
panel programmed through the Paradox keypad.
Dipswitch Setting
To allocate a block of IOC addresses for use by the Paradox alarm panel you
must first determine how many inputs you will need. For example if you need to
monitor the first 64 inputs you will need 64÷16 (inputs per IOC) = 4 IOC‟s. The
first IOC address will be # 5 representing inputs 1-16 and the last IOC address
will be #8 representing inputs 49-64. Use the above DIP Switch Selection table
to determine the dipswitch settings.

Axiom Installation Procedure
Keypad Setup
A password is needed in order to allow the Axiom system to arm and disarm the
panel. Password slot #2 is used for this purpose. The password is not
automatically downloaded to the virtual keypad so you must select “Set User”
and fill in the # 2 password used by the partition.
Keypad Links
Assign the links to Disarm, Home, Evening, and Away in the keypad
configuration.

Virtual Input Usage
In order to use the Paradox Virtual Input option the printer module must be
programmed to allow all 16 virtual inputs to be used and the inputs must be
programmed into the panel. An IOC16 must be added to Axiom with properties
set for all outputs and the address must match the Virtual IOC address set by the
PC100 dipswitch. Whenever a virtual output is turned on or off the
corresponding virtual input will open or close.
To use this feature apply a link to turn on or off the Virtual output in order to
communicate an open or closed zone on the alarm panel.
Virtual Input Programming
Follow the previous procedure for accessing the printer module programming
section (4003 followed by the device serial number).
Sections 700, 710, 720, 730, 740, 750, 760, 770, 780, 790, 800, 810, 820, 830,
840, 850 should be programmed for 1*******, the in-between sections should
remain defaulted.
Add the Virtual Inputs to the Alarm Panel
The virtual inputs from the printer module may be assigned to the alarm panel by
following the Zone Programming procedure in the programming guide. Not all of
the inputs have to be assigned.

DSC Alarm Panel Interface
The PC100 is used as a bridge between the Axiom Access Control System and
the IT-100 interface for the DSC alarm panel. To achieve this functionality the
PC100 emulates eight Safesuite™ keypads and up to eight sequentially
addressed IOC‟s.

Whenever a partition is armed or disarmed by the DSC system the
corresponding Safesuite™ keypad will display the status. For example if keypad
number 102 reports that it is disarmed it really means that Partition 2 has been
disarmed. For the virtual keypads there will be no zones assigned, instead the
virtual IOC‟s will reflect the input status. Using Links to arm or disarm a group of
inputs allows the virtual IOC‟s the capability of reporting the DSC panel‟s inputs.
Using an input group assigned to a virtual keypad allows the software the
capability of assigning any number of inputs to each virtual keypad.

IT-100
IOC Setup
Determine the number of IOC‟s needed to reflect the number of inputs in the
alarm panel. Add these IOC‟s starting from address #5 and make them all
inputs. Inputs that are used for entry and exit should be given an abort delay to
prevent false alarms. A link may be given to the entry zone to disarm the
follower zone when abnormal.

Input Groups
Create input groups by assigning the associated IOC inputs with partitions
There should be three groups of inputs for every partition:
1) Interior zones.
2) Exterior zones.
3) Entry zones.
Axiom Links
Create four links for every partition.
1) Disarm Link –Disarm Interior, Disarm Exterior, Disarm Entry.
2) Home Link –Disarm Interior, Arm Exterior, Disarm Entry.
3) Evening Link –Disarm Interior, Arm Exterior, Arm Entry.
4) Away Link –Arm Interior, Arm Exterior, Arm Entry.
Keypad Setup
A password is needed in order to allow the Axiom system to arm and disarm the
panel. Password slot #2 is used for this purpose. The password is not
automatically downloaded to the virtual keypad so you must select “Set User”
and fill in the # 2 password used by the partition. Some DSC alarm panels will
allow arming without a password. The password is used mostly for disarming the
partition.
Keypad Links
Assign the links to Disarm, Home, Evening, and Away in the keypad
configuration.
PD4401
Connect the PC4401 to the PC100 according to the drawing on page 2. The
DSR and DTR signals must be tied together in order for the PC4401 to
communicate properly.
After enrolling the module, program the PC4401 for 1200 baud as a DATALINK
type.

Abort Delays on Entry/Exit Zones
Assign abort delays on inputs used for Entry/Exit so that the inputs will not show
alarm when first opened prior to disarming the partition.
Axiom Links
Create two links for every partition.
1) Disarm Link –Disarm the input group associated with the partition.
2) Arm Link –Arm the input group associated with the partition.
Keypad Links
Assign the links to Disarm, Home, Evening, and Away in the keypad
configuration.
For example:
If there are 16 inputs and 2 partitions with the first partition inputs 1-8 and the
second partition 9-16, there will be two input groups assigned.

Wavetrend Long Range Reader Interface
In this interface the PC100 is programmed to communicate with Wavetrend
readers while emulating an RC-2 for an AXIOM system. WAVE57 (or higher)
firmware is required. It works with the NC100 firmware version 7.60 or higher
and software version 5.2.17 release3 or higher.
The wavetrend RF Tag reader model L-RX201 can be interfaced with the Axiom
Access Control System so that credentials can be tracked throughout an access
control installation.
Interface Method
The method of interfacing consists of a PC100 emulating eight RC-2s. Each
wavetrend reader attached to the reader network will be assigned to its own
virtual RC-2.
For example: five readers attached to a network.
Reader #
RC-2
1
RC #1 Side A
2
RC #1 Side B
3
RC #2 Side A

RC #2 Side B
5
RC #3 Side A
DIP-SWITCH Settings
The Axiom Access Control System starts its RC addresses at address 1 and can
support up to eight devices ending at address 8. To make the DIP-switches
capable of selecting the range of addresses to which the emulator will respond,
an offset address scheme has been developed. The first four switches create
the start offset and the last four switches create the end offset. Desired
Address = DIP address + 1. The device when polled will answer any address
that falls between the desired start and end addresses (inclusive). If the end
address is smaller than (or equal to) the start address only the start address will
be used.

NC100 Firmware Version
Version 760 (or higher) is required for use of wavetrend readers. Selecting the
72-bit WTND format for an access point will enable the use of the long-range
readers and credentials.
The NC100 firmware has been designed to ignore the continuous stream of card
data from the wavetrend readers unless the card has moved from one zone to
another. A special buffer has been reserved to store ID‟s along with a timer and
RSSI value. The timer is refreshed on every transaction for each card in the
buffer. If the timer times out the card will be reported as missing. The extended
unlock time is used as the value for this timer. A value of 60 seconds works well
with 10 credentials.
RSSI Values
The RSSI value is the Received Signal Strength Indicator. This value ranges
from 50 to 255 depending upon how close the card is to the reader and how the
reader is set up.
If a reader has an antenna attached, the RSSI value of a card 3 meters away will
be around 100. Without an antenna the same card will report around 60.
The RSSI value is displayed in the AXIOM cards monitor screen. This can be
used to adjust the RSSI threshold so that the zone area can be limited to a
particular distance.
RSSI Threshold
The DHO warning time is used as the RSSI threshold value. To use a value
greater than 127 select minutes and calculate adding 128 to the value. As an
example: to achieve an RSSI value of 140, set the time to minutes and use a
value of (140 –128) 12. The received RSSI value will be displayed in the AXIOM
V cards monitor.
RSSI Background Messages
A credential will transmit its ID every 1.5 seconds. This message is translated
into an RC-2 style 72-bit wiegand style message by the PC100. Part of the
message contains the RSSI value of the card. Whenever the value of the RSSI
for a particular card has changed by more than the Unlock Time the message will
be transmitted. To prevent moving targets from swamping the C-NET with
unnecessary background messages the unlock time should be set to above 60.
For stationary credentials and during installation this value may be lowered.
Card Missing Timer
The Extended Unlock Time (EUT) is used as the “card missing” timer. If the EUT
is set to 0 a default value of 60 seconds will be used. Once a card has been
received and placed into the buffer, the timer will be decremented every second.
When the timer times out an “Access Denied – Missing Card” log message will
be recorded.
