Hi,

Progress on my modular led display is going nicely. The modules will be placed in a grid of up to 4 by 16. Each module is fitted with a dual rs485/rs232 transceiver, so that a module can act as both a rs232 to rs485 converter, and a rs485 repeater.

Do you guys have an recommendation for selection on connectors and cabling? The PCB headers must be SMD (the other side of PCB is packed with LEDS)

I'm currently at IDC and ribbon cable, but i'm hoping there's a better alternative.

Better in what respect? Assuming you lay out the conductors correctly, the IDC connectors are probably the cheapest and simplest method.
