3.7.3.3
As a master device the ISAC-SX TE can program and control other devices attached to
the IOM-2 interface. The master mode is selected by default if one of the possible
microcontroller interfaces are selected. The monitor data is written by the
microprocessor in the MOX register and transmitted via IOM-2 DD (DU) line to the
programmed/controlled device e.g. ARCOFI-BA PSB 2161 or IEC-Q TE PSB 21911.
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 chapter
Chapter
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 type of MONITOR
command.
3.7.3.4
In applications without direct host controller connection the ISAC-SX TE must operate in
the MONITOR slave mode which can be selected by pinstrapping the microcontroller
interface pins according
transceiver part of the ISAC-SX TE is programmed and controlled by a master device at
the IOM-2 interface. All programming data required by the ISAC-SX TE is received in the
MONITOR timeslot 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
The first byte of the MONITOR message must contain in the higher nibble the MONITOR
channel address code which is ’1010’ for the ISAC-SX TE. The lower nibble
distinguishes between a programming command or an identification command.
Identification Command
In order to be able to identify unambiguously different hardware designs of the ISAC-SX
TE by software, the following identification command is used:
DD 1st byte value
DD 2nd byte value
The ISAC-SX TE responds to this DD identification sequence by sending a DU
identification sequence:
DESIGN:six bit code, specific for each device in order to identify differences in operation
