with the Topcat and Swampfox RTUs to allow communication with one or more
IEDs with isolated RS485 interfaces.

and converter:
Connection to Non-Abbey Equipment
The converter requires the RTS signal to control the RS-485 transmitter. The signal
must be active during RS-485 transmission, and inactive during reception.
Power is supplied via PIN 1 and can range from +8 to +27.6V DC, which is normally
supplied from the Abbey Systems RTU. A splitter cable can be used to power the
converter from a suitable supply if this not available on the equipment's serial port.
