Cordless Serial Adapter General Connection Information

There are quite a few factors involved in getting the CSA setup the way you want it to communicate with your hardware including but not limited

to:

The device you are connecting the CSA to The Bluetooth hardware and software you are connecting to the CSA with The application on the device that will be communicating to the hardware.

For the hardware that you are trying to communicate with you will need toverify what RS232 line signals are in use. The main problem with the CSA and connecting hardware is that in order for the CSA to work correctly device must only be communicating the base TX and RX lines similar ot a modem in order to work correctly. If your hardware communicates data similar to a modem then it should work fine. However most custom serial devices tend to use the other RS232 line signals for additional data or information to be sent across the line wheras the CSA will only work when it needs to send out data on RS232 signal lines:

2 (IN RXD)

3 (OUT TXD)

and if the DTR is NOT asserted by your device and you have made sure that when you configured the CSA to uncheck the DTR assertion then two additional lines of information are sent and that is:

4 (OUT DTR)

6 (IN CSR)

So if your hardware sends any additional information on lines 1, 5, 7 or 8 then it will not work with the CSA. If your device requires that you disable flow control then what you need to do is use a custom adapter or cable to loop lines 7 and 8 coming out of your device as we do not have the ability to configure that in our CSA configuration software.

The CSA is only meant to be used as a replacement for a connection that utilizes the base transmit and receive lines.

If you need additional assistance please gather the following information BEFORE contacting support:

What device is the CSA connected to it that you are trying to communicate with? Who makes it, what does it do and can you confirm the signal pinout of the port on the device?

Is the hadware a DTE or DCE device?

Do you know if the hardware supports Hardware Flow Control or can you verify that the flow control line is set to the Flow On state?

Can you describe what the serial data is as it comes out of your device?

For example, when you turn on or power the device is it immediately sending out serial data right off the bat or do you initiate the data connection from the software? is it at a constant rate of a certain bps or is it ininterval steps?

These are some things to check for as serial communication devices can be deceptively complex.

Another way to troubleshoot your connection is to test with another serial port device such as hooking the CSA and the null modem adapter to a serial port of another PC and testing if you can open a Hyperterminal window and communicate to your device.
