Installation of the Gateway
To install the gateway, perform the installation procedures described in the following sections, in the order in
which they are presented.
1.
Wire the upstream host communication.
2.
Wire the power input.
3.
Wire the downstream device communication.
4.
Cycle power to the device.

Unsupervised Alarm Inputs: Power Fault and Cabinet Tamper
Monitors
On the wireless reader gateway, there are two unsupervised alarm inputs that can be used for power fault and
cabinet tamper monitoring. These inputs are connected using the Input 2 (IN2) and Input 1 (IN1) contact
terminals on the wireless reader gateway board.
Input 2 and Input 1 are both simple N/C (normally closed) contact closure monitors.
Wire the Input 2 and Input 1 contacts using twisted pair cable, 30 ohms maximum. (No EOL resistors are
required.)
Note:
If either of these inputs is not used, a shorting wire should be installed.

Upstream Host Communication
The wireless reader gateway uses Port 1 to communicate to the ISC. Port 1 should be wired as 2-wire RS-
485 interface for multi-drop or extended distance communication.
For RS-485 communication, the following type of RS-485 cable is required: 24 AWG (minimum) twisted
pair (with shields). 2 twisted pair RS-485 cable configuration should be used. The RS-485 cable should be
