I have a cash drawer attached via a CD101A cable to an Epson TM-T88V. OPOS drivers installed and objects configured. Check health works for both devices.
Created a hardware profile and entered the logical names for the printer and drawer into the profile.
Open MPOS, pair with the dedicated hardware station and everything seems fine. Print X prints fine, so its communicating with the printer fine. But, if I hit the Open drawer button on the MPOS screen, nothing. If I try a tender removal, drawer doesn't open. A cash sale... receipt prints, but drawer doesn't open.
So, I know it works because from the Epson OPOS program I can check health and it pops open. In the hardware profile its named CASH1 and that's the name in the Epson program.
What am I missing or doing wrong?
