In applications without direct host controller connection the IPAC-X must operate in the
MONITOR slave mode which can be selected by pinstrapping the microcontroller
interface pins according
transceiver part of the IPAC-X is programmed and controlled by a master device at the
IOM-2 interface. All programming data required by the IPAC-X is received in the
MONITOR time slot 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 IPAC-X. 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 IPAC-X
by software, the following identification command is used:
DD 1st byte value
DD 2nd byte value
The IPAC-X responds to this DD identification sequence by sending a DU identification
sequence:
DU 1st byte value
DU 2nd byte value
DESIGN:six bit code, specific for each device in order to identify differences in operation,
e.g.000001IPAC-XPEB 21150 V1.1.
This identification sequence is usually done once, when the terminal is connected for the
first time. This function is used so that the software can distinguish between different
possible hardware configurations. However this sequence is not compulsory.
