The MONITOR channel can be used in following applications which are illustrated in
figure 22:
• As a master device the SCOUT-DX can program and control other devices attached
• As a slave device the codec and the transceiver part of the SCOUT-DX is
• For data exchange between two microcontroller systems attached to two different

programmed and controlled from a master device on IOM-2 (e.g. JADE PSB 7238).
This is used in applications where no microcontroller is connected directly to the
SCOUT-DX. The HDLC controlling is processed by the master device therefore the
HDLC data is transferred via IOM-2 interface directly to the master device.

of a dedicated serial communication path between the two systems. This simplifies the
system design of terminal equipment.
