      I bought one of these but it didn't work reliably - the negative charge pump didn't work right most of the time. I replaced the MAX3232 IC, and also shorted pins 10 and 11 on it so that no logic-level inputs were left unconnected. It works fine now. YMMV

      Forgot to mention I bought it through Digi-Key, and the IC was replaced with a TI-branded one. You might want to double-check the source used for the ICs.

      Do you also support TTL-RS485? Must be autoswitching... MAX485 signalling only works if you control both sides of the conversation.
