Before setting this function, make sure connection of a RJ45 cable from the
Ethernet connector on the ACU to the Modem or conect a 9 pin serial cable from
the RS232/422 connector on the ACU to the Modem.

Use Mediator must be set to “NO” if there is no MEDIATOR
connected to the ACU. Improper setting of this parameter will
cause your ACU’s Modem interface to work incorrectly.
