Hi,
I just bought an allen bradley 1747 10 slot rack, PSU, CPU, input & output modules.
I also bought one of these to connect my a usb port on my windows XP laptop to the serial connector on the processor:

I configured a DH-1 driver, managed to configure the correct com port and rslinx automatcially configured the baud rate (to 1200 i think).
When unconnected the processor FLT & DH485 lights are flashing. When I have the SLC 03 shown on the laptop graphical representation the rs232 light starts flashing as well.
Can anyone tell me what is causing the FLT led to flash red?
Thanks,
James, (PLC newbie).
