What PC application are you using to talk to the SSC-32? SEQ, or LynxTerm, or something else? Have you used the RF modem sucessfully before? What baud rate is it capable of working at? 2400, 9600? You can’t just start changing connections and setting haphazardly and hope it will work.
You may need to do basic trouble shooting on the wireless equipment. I’d jumper the tx/rx on the remote wireless device, and then see if characters sent from the pc are received back at the pc.
I thought the same thing, but it’s a one way trip with this device. 
This is where a cheap analog multimeter may be of use (walmart has them for ~$10, and the cheap ones do not have dampened meters). Connect the meter between the serial output and ground on the remote wireless device such that the meter is showing a positive voltage (usually ~5-12v). Then send a long string of "a"s from the pc. If the remote wireless device is sending out serial data, one should see a momentary quick dip in voltage on the meter. This can be first tried on the serial port output on the pc to see how it works. It is a simple hardware way to see if something is actually being sent from the serial port.
I’m using the same method as mention in the Bluetooh thread.
Instead of LynxTerm --> BT BT–> SSC32 I’m using LynxTerm --> RF RF–> SSC32
As the pin connections are all similar to that of the BT module: TX/TR/+5/GND
Tried sending “VER” as mention in the thread but got 0 byte read.
Will try this out on monday.
cheers 
I have read through the RF transmitter info. It is a one way connection. There is no way to receive the version reply unless you have a separate receiver and transmitter on each end. Is that what you have?
What baud rate are you using? It looks like 19.2k is the limit.
Yup, I’ve a seperate RX/TX antenna on the computer and on the SSC32 side
i tried all settings including 9600 and 115200.
I’s build a RS232 to TTL converter(MAX232 chip) and connected pin-to-pin via the serial port as it there is an actual RS232 cable running from the computer to the SSC32 board…
Still no luck 
The RF modules are only good for 19.2k so trying it at 115.2k is a waiste of time. For a test start LynxTerm, and power everything up, but turn the SSC-32 on last. The green LED should be on. Try typing ver and enter. Does the LED go out? If it goes out that means the SSC-32 is receiving data. Note, it will go out even if the baud rate is incorrect. This test will let us know if the SSC-32 is receiving any data at all.
