Our other projects prevent us from putting too much time into this effort at the moment (but we’ll get back to it in the future for sure!) but we did whip up a super-simple VB tool to send arbitrary hex bytes to the device.
Since we are using a USB->RS232 converter we are free to set our com port to anything we want. We used COM1 so the program is hardwired to use COM1. What do you want for 15 minutes worth of work? The program expects hex bytes in the upper text box, space delimited. Upon Send CMD it will open the RS232 port and send the bytes, printing any corresponding output in the lower text box. Finally, it will close the RS232 port so other software can use it.
Yes it’s a piece of junk, but it’s a starting point/example you can use for your own tools. Plus, if we go too long without writing the code for unhex() we tend to forget and have to go look up the ascii table to remember how to do it. It’s VB6 and the source is included.
