UNC- 1 00 C o m m u n i c a t i o n
The UNC100 has one RS485 port and an Ethernet 10/100 interface. Communications from the host
computer running Axiom software can be achieved in the following ways; either via the Ethernet interface
or via RS485 through a direct connection to a designated channel. The UNC100’s RS485 channel may be
programmed as HOST, DNET, UNC-NET, LAN, and OSDP/OSDP-S. Use the DIP switch to select baud
rate for Host communications as 9600, 38400, 57600, or 115200.
Networks
There are three networks supported by the UNC100 these are:
1) Host Communications through the Ethernet. Host communication between PC and UNC-100 can be
encrypted by using AES-256 bit encryption.
2) Device Communications for devices such as additional RC-2s starting at address 2, Alarm Keypads,
IOC-16 controllers, and PC100.
3) Controller Communications for controllers such as additional UNC500s or for UNC100s via :
a. UNC-NET, a protocol designed for RS485 communications between UNC100’s and
UNC500s.
b. E-NET, a method designed using Ethernet port rather than physical RS-485 connections
between UNC100’s, and a mix of UNC100s and UNC500s
RS485 Applications
The Host port connects the UNC100 to a PC through an
RS485 interface.
The D-NET (Device Network) connects local device
controllers (RC-2, IOC-16, SafeSuite™ Panels, NRC2000, or
NURC2000) to the UNC100 controller on a high-speed bi-
directional RS485 network.
The UNC-NET (Controller Network) connects the UNC100
controller to other on a high-speed bi-directional RS485
network.
Open Supervised Device Protocol (OSDP) communication
protocol is for interfacing one or more Peripheral Devices
(PD) to a UNC100 controller. The communication over
OSDP can be encrypted/unencrypted. When encrypted,
OSPD-S option need to be selected (Available in Firmware
10.28 and up.)
