Monitor Channel, normal End of Transmission
2.2.4.3
As a master device the SCOUT can program and control other devices attached to the
IOM-2 interface. The master mode is selected by default if the microcontroller interface
is used. The monitor data is written by the microcontroller in the MOX register and
transmitted via IOM-2 DD(DU) line to the programmed/controlled device e.g. ARCOFI-
BA PSB 2161. The transfer of the commands in the MON channel is regulated by the
handshake protocol mechanism with MX, MR which is described in the previous
chapters 2.2.4.1 and 2.2.4.2.
If the transmitted command was a read command the slave device responds by sending
the requested data.
The data structure of the transmitted monitor message depends on the device which is
programmed. Therefore the first byte of the message is a specific address code which
contains in the higher nibble a MONITOR channel address to identify different devices.
The length of the messages depends on the accessed device and the command
following the address byte.
2.2.4.4
Applications in which no controller is connected to the SCOUT it must operate in the
MONITOR slave mode which can be selected by pinstrapping the microcontroller
interface pins according to chapter 2.1. As a slave device the codec and the transceiver
part of the SCOUT is programmed and controlled by a master device at the IOM-2
interface. All programming data required by the SCOUT are received in the MONITOR
time slot of channel 0 on the IOM-2 and is transferred in the MOR register. The transfer
of the commands in the MON channel is regulated by the handshake protocol
mechanism with MX, MR which is described in the previous chapters 2.2.4.1 and 2.2.4.2
