2) Set the SW2 baud rate switch on the front
panel to 300 or 1200, as appropriate, after the
PIOU/PIOUS has been installed in the Expan-
sion Unit (in-300 bps—out-1200 bps).
3) Set SW3 to MODEM position for IMDU opera-
tion.
4) Set the P13 jumper plug on the PIOU to the
BELL position; or, cut the W4 jumper on the
PIOUS for BELL operation.
5) Mate IMDU connectors J1, J2, and J3 with
PIOU or PIOUS connectors P1, P2, and P3
(refer to Figure 5-20).
NOTE:
PIOU or PIOUS connectors P1, P2, and P3
are positioned to allow installation of the IMDU
only in the proper position.
6) Apply firm, even pressure to IMDU to ensure
proper mating of connectors.
NOTE:
The IMDU default station intercom number is
619; and IMDU communication parameters are
7-bits, even parity, 1-stop bit.
7) Refer to Programming Procedures, Section
100-816-300, Program 77-1, and set LED 14
to ON to enable IMDU operation.
