Apologies if this isn't the correct place to post this. It's not strictly an electronics design issue. In addition, it may be a stupid question.
I have an RS485 transmitting device at L1. I have an RS485 receiving device at L2.
I get from L1 to L2 by the following steps:
At L1 I convert the RS485 data to RS232 data and feed it into a modem. At L2 I read the data via the modem and convert it from RS232 to RS485 again.
At L1 I mismatch the TX+/- lines (ie. L1 device TX- connects to RS485 converter TX+, and L1 TX+ to RS485 converter TX-).
At L2 I mismatch the TX+/- lines (ie. L2 device TX- connects to RS485 converter TX+, and L2 TX+ to RS485 converter TX-).
Will L2 receive the data transmitted by L1 correctly?
That is, will both mismatches cancel each other out?
