IT-230 INTERFACE PRE INSTALLATION CONFIGURATION

This IT-230 Interface is fixed and shall be installed in the panel by service persons only (service person is defined as
a person having appropriate technical training and experience necessary to be aware of hazards to which that per-
son may be exposed in performing a task and of measures to minimize the risks to that person or other persons).
The IT-230 shall be installed and used within an environment that provides the pollution degree max 2, over voltages
category II, in non-hazardous, indoor locations only. This manual shall be used with the Installation Manual of the
panel which is connected to the IT-230. All instructions specified within the panel manual and the C24-HUB manual
must be observed.
All the local rules imposed by local electrical codes shall be observed and respected during installation.

Running the RS-422 Cable

An RS-422 cable must be connected to the C24-HUB and cable run to the IT-230 module inside the panel.
NOTE: Maximum cable length for RS-422 cable is 305 m (1,000 ft.)
At the C24-HUB, attach wires for RS-422 connection as follows:
1. Securely fasten the TX+ wire on the terminal block.
2. Securely fasten the TX- wire on the terminal block.

3. Connect a 120 , ¼ W resistor between RX+ and RX- terminals on the C24-HUB.
4. Securely fasten the RX+ wire on the terminal block.
5. Securely fasten the RX- wire on the terminal block.
6. Securely fasten the GND wire on the terminal block. (Optional, DSC recommends connection.)

Hardware Factory Default

The IT-230 can be hardware reset to Factory Default by removing AC power, Battery + terminal, and telephone
line, then installing a jumper between the BLK and DEF pins on the IT-230 Keybus connector (left terminal
block) and restarting the IT-230. (See Figure 2.)
NOTE: Installing the Default (DEF) jumper during normal operation has no effect.
