E3X-232FP
RS-232 Serial Box
E3X-232FP-WCS
Overview
The RS-232 Serial Box is a data interface radio transceiver which can be connected to any system that uses an RS-232 serial port.
The device communicates with ILLUMRA wireless switches, sensors, and receivers and allows other systems to communicate with
ILLUMRA wireless controls.

Components Included
The following items are included with this product:
■
A -- () ILLUMRA RS-232 Serial Box
Installation
The RF Serial Box can be mounted almost anywhere. The following considerations should be taken into account:
Mount within range of wireless switches and receivers; obstructions limit range (see specifications)
■
■
Mount in area where power source is available (see specifications)
■
Do not exceed max RS-232 cable length
■
For optimal range:
-- Do not mount or place RF Serial box close to the floor
-- Do not mount or place RF Serial box inside a metal housing
Connections (Interfacing Protocol)
The RF Serial Box can accept external power through either the power connector, or through pin 9 of the DB9 port. When using
an external power source, connect to the power jack using the provided screw terminals. The power connector accepts 8-28 VAC
or 8-30 VDC. The power connector is polarity insensitive, but power provided through the DB9 port must be DC, not AC, and
connected with correct polarity (+ to Pin 9, - to GND).
A standard DB-9 female connector is provided on the device. It may be necessary to connect the Serial Box to the security/control/
automation panel using a null-modem cable, but connection to a PC requires a standard straight-through cable.

Octet Signals and Bit Order
■
9600 bps; 8 data bits, no parity bit, one start bit, one stop bit
■
Line idle is binary (standard)
■
Each character has one start bit (binary 0), 8 information bits (least significant bit first) and one stop bit (binary 1)
■
The signal levels shown in the timing diagram are inverted from the voltages that appear on the RS232 connector.
