As always, any help would be appreciated.
The task: interface an OPII with this devide (flyer attached).
I am using a Serial Connectivity Adapter Kit from HAI to make the connection. The DB 9 is being hooked to reverse gender DB 9 with a RJ 45 on the other end which plugs in into the Somfy device. Here is what the flyer says about the pinout configuration:
RJ45 Pinout
Pin 1,2: RS-485
Pin 3: Transmit (TX)
Pin 4,5: DC+
Pin 6: Receive (RX)
Pin 7,8: DC- (Ground for RS-232)
Pins 1&2, 4&5, 7&8 internally connected
I confess that I am absolutely ignorant about Rs 232 and RS 485. I have tried just about everything with no joy. Can anybody help with what goes where (pinouts)?
Thanks.
