INTRODUCTION
The Order Wire Module (Figure E-1) is an optional adapter for the MDS 4310 Transceiver
which makes two-way voice communications possible for the initial set-up and testing of the
radio link. If the Order Wire Module is connected between the transceiver and the RTU, and
a telephone handset is plugged into the Order Wire Module, it is possible to listen to the data
communications on the channel. Receiver audio from the transceiver can be monitored by
using the earpiece on the handset. Speaking into the handset microphone activates the VOX
circuit in the adapter, allowing voice communications with the master or base station.
As a convenience, the Order Wire Module has been designed to work with a standard four-
wire modular (RJ-11-4) telephone handset, available from any telephone supply store or
electronic parts distributor.
