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>”
