makes it wireless. The wireless transmitter module
connects to an RS232 device. The wireless receiver
module connects to the PC via USB interface.
The PC communicates with the RS232 device
though the wireless receiver module. The wireless
transmitter/receiver modules are transparent to

device.
The transmitter/receiver module comes with two
LED indicators. The green LED indicates wireless
data transmission (TX). The red LED indicates

there is data activity on the RS232 port, otherwise the
RF module is set to sleep mode to save power. This
mode may be selected when the wireless transmitter
is connected & powered by a battery powered device.
While the RF module is in sleep mode, there is no
wireless communication between the transmitter &
receiver modules. The RF module can only be wakened
from the RS232 device when there is data activity.

Transmitter/Receiver Configuration
The Configuration CD comes with "wizard"
software which allows the user to read or change
the configuration of the transmitter/receiver. You
need to install the software by following the menus.
Once the software is installed, you can configure the
transmitter (thru RS232 connection) or receiver (thru
USB connection) from the PC software.
You can change the baud rate and/or the channel
number for the transmitter/receiver using the wizard
software. The baud rate and channel number for the
transmitter should always match the receiver settings,
otherwise the two modules will not communicate.
Mounting Bracket & Installation
The wireless transmitter/receiver can be mounted
using the optional mounting bracket. In order to
assemble the mounting bracket to the module, the two
case module screws are used.
