Establishing Communication with the PDX

Print Friendly and PDF
Here are two important tips that will help you establish communication with the PDX. After you have connected in terminal mode using X-ware, you will notice that you do not see a prompt ">" like some of the other x-ware products. This is normal. The PDX does not return a prompt at the terminal.

In order to verify your communication with PDX you need to know that the default address for the PDX is 8. Unlike some the other X products which default to 1, the PDX has three hardware address select inputs on the 25 pin connector which if left untouched result in a address of 8. In order to get a response from the unit you must precede the command with a valid device address. One of the best commands to help determine a devices address is the R command. Issuing 8R(be sure to use capital letters) should give you a response of *R, *S,*B , *C . If you do not see a response to this, the unit may have been set to a different address in which case you will need to try a different address with the R command, like 1R,2R, 3R until you receive a response.
