Remote operation
Introduction
Introduction
The general principle of operation is that the settings on the slave unit
are relative to the settings on the master unit which allows the manual
and remote interfaces to operate in the same way. It is therefore
necessary to always consider the relationship between the two timeslots.
Call setup and changing channels are handled by the master unit.
However, it is vital that the slave unit remains on the same channel and
timeslot (offset by one) as the master unit. Unlike the manual user
interface, where a change made on the master unit is copied to the slave,
controlling the system remotely involves taking control of both units. As
most of the settings on the slave unit are relative to the master unit, the
slave unit must know the configuration of the master unit. The following
command sequence is a general example of how this is achieved.
MasterAddr=715
SlaveAddr=716
OUTPUT MasterAddr;”HSCSD:MASTER:COMMAND <parameters>”
OUTPUT SlaveAddr;”HSCSD:MASTER:COMMAND <parameters>”
OUTPUT SlaveAddr;”HSCSD:SLAVE:COMMAND <parameters>”
