Quick Start Guide
This quick start guide is often the only setup procedure required to put the SSRT-x9-RS232 RF data transceivers
into operation. The advanced programmable features of the transceivers covered later in the manual are not re-
quired in order to setup a functional wireless data link .

Connection to DCE RS232 Host Devices
As mentioned above, the SSRT-x9 serial port is configured as a DTE device. Connection, therefore, to DCE host
devices requires a straight through serial cable and does not require and data crossover adapter.
Serial Port Pin Assignment
Connection to DTE RS232 Host Devices
The serial port of the SSRT-x9-RS232 data transceivers are DTE config-
ured DTE (Data Terminal Equipment). This is the same configuration as
a PC’s 9-pin serial port. With this considered, if the host device serial
port is configured as a DTE, then a null modem (crossover) data con-
nection is required between the host and the SSRT-x9-RS232 transceiv-
ers. A null modem cable or crossover cable will correctly connect data
inputs to data outputs of the two devices.
If a straight though (serial extension) cable is used between the SSRT-
x9-RS232 and DTE host then a null modem adapter must be inserted.
