Hi Guys,
I have a Mark IV board that passes all tests up to but not including the first Serial port test. I heard on the Multicomp PCB forum topic that Dr. Acula has 50 MAX232 chips that are fakes. Well the Mark IV doesn't use the MAX232 chip, instead the MAX233CPP ship is used. All I get on the first serial port test is the output in putty looks like an incorrect BAUD rate. What details do you need to remotely troubleshoot this problem. My Crystal is 18.432MHZ. Is this crystal frequency the source of my problem. I will be ordering parts very soon as in a few days for the new Cyclone IV board I recently received and I would like to get all my parts orders into one order, Thanks in advance for any help in getting my Mark IV board fully functional. Take care my friends.
