Quote from: centra on February 01, 2013, 03:08:00 PMHello!We want to use the MOD-RS485-ISO to use RS485, as we were recommendet by our distributor. Unfortunately the device doesn't work. The signals from the RS485 are not put through to the RS232. We never worked with OLIMEX-devices before, so what could be the problem?The voltage is ok on both sides. An other idea was, that the controller isn't preprogrammed, but I hope that this isn't the problem (we should have be informed about). Or do these products have to be programmed by the user?We also just want to use the device as a RS232-RS485-Transceiver and not connect it to a development board from Olimex.Thank you!

Quote1) enabling UART on every startup (done over I2C)2) modifying the firmware to have UART enabled by defaultIs this correct?
QuoteIf so, it seems that I have to order the PIC-KIT3 as soon as possible, isn't it?
