I'm trying to communicate with a Solartron 7151 using RS232 and failing.
I've made up a cable DB9 to DB15 wired straight through based on the information on page 6.6 of the user manual which shows the pin assignments of the DB15 connector on the back of the DMM.
DB9 Pin 1 DCD not connected
DB9 Pin 2 RxD to DB15 Pin 3
DB9 Pin 3 TxD to DB15 Pin 2
DB9 Pin 4 DTR to DB15 Pin 15
DB9 Pin 5 GND to DB15 Pin 7
DB9 Pin 6 DSR not connected
DB9 Pin 7 RTS to DB15 Pin 4
DB9 Pin 8 CTS to DB15 Pin 5
DB9 Pin 9 RI not connected
I didn't connect DB15 Pin 10 to anything, as there is nothing on a DB9 that provides Receive Clock - all my serial ports are DB9.
Unfortunately it doesn't work.
If anyone knows how it should be wired, please could they let me know?
