(newbie, please forgive ignorance of this subject)
VSI-Pro is a tillscan interface to overlay epos sales data onto a camera image recorded onto a cctv recorder. I would like to collect the sales data from the serial port on the tills and input it to the VSI-PRO. This system was working but was shelved for a couple of years during a refurb.
There are 2 tills
Geller ET6600 (c/w internal serial interface board)
Geller ET6800 (serial port on left side of till)
There are 2 VSI-PRO tillscan interfaces (circa 2000)
What I've tried and failed:
Serial at till: pin3 = data +, pin5 = ground
Serial at VSI-Pro: pin2 = data+, pin5 = ground
20M cable run using CAT5e cable
VSI-Pro programming:
REGISTER SELECT: (Tilltype) = Generic
COMMUNICATIONS:
RX baudrate = 9600
TX baudrate = 9600
parity = even
databits = 7 (also tried 8.)
handshake = off
auto linefeed = off (also tried on)
Can someone point me in the right direction, please?
