Newer motherboards do not come with an onboard serial port, which means communication over the SMR bus must be done through USB. By using a FTDI USB-RS422 cable it is possible to connect directly to the SMR bus. The FTDI cable comes as a wire-end and can be soldered to a square 6 position connector used on the SMR's, shown below.
If the following connections are done the cable going from the original RS232-RS485 converter can be used. The rightmost numbers on the figure are the plug connections.
