DMX501
The DMX501 modem module can be configured for point-to-point
line or for a multidrop modem network. If a modem is configured for
multidrop use, the outgoing carrier is valid only during transmission.
If MAWS is the master in the multidrop network, DMX501 can be
normally configured for point-to-point use.
