Hi All,
I just received and powered on the contact closure board (ZSCAN16PROXR) and the relay expansion board (XR85) and having some problems / confusions
I installed the latest and greatest FTDI VCP drivers as off this posting.
Base Station Issues
When I launch the Base Station software after plugging in the ZSCAN16PROXR to my computer the Base Station software says it cannot connect to my device and then starts cycling through other baud rates in hopes it finds it. I know that I have the correct COM port selected as my C# test application is able to communicate with it and see the contact closure value change as I press the button wired to the board. Why is it cycling through the baud rates when I can successfully communicate with it using my own home grown software?
API Issues
I’m confused on the API a bit. I have been following the ProXr Quick Start Guide for the command set I can send to the board to get the status of specific contact closures. While the commands are correctly being processed by the board the response doesn’t seem to be lining up with those documented in the quick start guide. Specific it’s the header value from the board transmits to the host. For example, when I query the status of the bank 1 contact closures I send the following command
0xAA, 0x03, 0xFE,0xAF,0x00, 0x5A
The response as documented in the quick start guide says I should receive a message with a header value of 0xAA, but I am receiving a header value of 0x3F. The full response I receive when the contact is open is:
0x3F, 0x01, 0x00, 0x3F
I get the same response header value for all other commands I send the board including the “Test Communications Response Command (0xAA, 0x02, 0xFE, 0x21, 0xCB)” that I found on the website. Why is this? Is my board running older firmware or is the Quick Start Guide out of date?
Also Is there a spread sheet or some kind of website that details all the commands/API that can be sent to the controller and the expected response we should receive?
