Hi, I have this PC, but I can't see on his motherboard does he have COM header. I need 2 COM ports on the motherboard, because they're powerful enough to talk to ESC/POS printers which are 25-30m away.

Solved! Go to Solution.

Download the Hardware Maintenance Manual for your particular system model, M58p is the system type, the model will be a 4-digit number, like 6137. Find the port and connector diagram for the motherboard.

I've found it locally - it's kinda strange this COM2 header - it has 6 pins 1st row and 5 pins in the 2nd row. Am I crazy or this is proprietary header? I couldn't connect it! Thank you.

I've figured out how to handle this thing, don't worry. I just need to replace expansion card with MosChip based.
Well done! Can you expand on what an expansion card with a MosChip is? And how it fixed your problem.

RS232 add-on card on PCIe with 2 RS232 ports. Even the cheapest will be enough to make signal over 50m to kitchen printer. Ofcourse the cable also matters! This was my task actually.
