The RS-232 wireless bridge is designed to be a transparent bidirectional three-wire RS-232 cable
replacement. The RS-232 Wireless Bridge has a DB9 DCE female connector for data and for the internal
radio module configuration, and a micro USB port to configure settings that are specific to the RS-232
Wireless Bridge. The RS-232 Wireless Bridge is available in three different options differing by frequency
and RF power output.
It is possible to mix and match Wireless Bridge products. The RS-232 Wireless Bridge will communicate
with the RS-485, Analog and Digital I/O and USB Wireless Bridge products that share the same radio
configuration. By using an RS-485 Wireless Bridge at point A and a RS-232 Wireless Bridge at point B, the
wireless bridges can act as a RS-485 to RS-232 over-the-air converter.

Fig. 1 Mechanical Dimensions
The mechanical dimensions for the Wireless Bridge are shown in Figure 1. The mechanical dimensions
are shown with the optional DIN rail mount bracket which is not included with the standard part
number. Mechanical data for the antenna is not shown.
Pinout and Wiring
The pinout follows the standard RS-232 Data Communications Equipment (DCE) device. Signal names
for RS-232 are defined from the standpoint of a Data Terminal Equipment (DTE) device. The signal
named Receive Data is an output from the RS-232 Wireless Bridge and the signal named Transmit Data is
an input. Not all RS-232 signals are implemented on the Wireless Bridge. Only Transmit Data, Received
Data and Ground are required for basic function. The DTR input may be used to control the pin sleep
function on the internal radio for reduced power draw.
