Example of PC Interface
If an external signal is required to enable the transmitter of the adapter, the Transmit Data pin from the PC can be used
as an enable pin. An adapter can be wired to ensure that the transmitter is enabled when data is sent, thus actively
driving Highs on the RS485 line.
If the RTS line is used by the RS232/RS485 adapter, the following adapter can be placed between the PC
Communications port, and the RS232/485 converter. WinDrive uses only the Transmit Data, Receive Data, and Signal
Ground Pins on the PC Communications port.

For details of wiring for a specific RS232/RS485 adapter, consult the data-sheet for the particular device.
7.4.2.2 RS232/RS485 adapter
The RS232/RS485 adapter recommended by MOOG for operation with WinDrive and the RMC/DMC and T200 is
PSM-EG-RS232/RS485-P/2D, PN2761392 from Phoenix Contact.
