Only one RSIU can be installed per DK424 or DK424i system. When the RSIU PCB is installed,
the RSSU, PIOU2, PIOUS2, IMDU modem, and PEPU PCBs can still be installed with all of their
respective paging, modem, and RS-232 port functions available; however, five RS-232/modem
ports can be installed in one DK424 or DK424i system.
When installed together in the same DK424 or DK424i system, the RSIU, PIOU2, PIOUS2, RSSU
port functions are identified and enabled (turned On/Off) in system programming. If the same
function is programmed for an RSIU port and a PIOU2, PIOUS2, RSSU port, only the RSIU port
will function.
RSIS, RMDS Piggy-Back Installation
1. Install all RSIS and RMDS PCBs on the RSIU PCB before installing the RSIU into the DK424
or DK424i. Each RSIS or RMDS piggy-back PCB is installed on the RSIU PCB as shown in
Figure 4-38.
Up to three RSIS PCBs can be installed on the RSIU PCB; only one RMDS PCB can be
installed on the RSIU. The function and bit-per-second (bps) data rate of each RSIS and
RMDS circuit port is set in Program 76 as described in the Programming Part that follows.
2. After installing all RSIS, RMDS PCBs, install the RSIU into the DK424 or DK424i per the
following instructions.
RSIU Installation
1. The RSIU must be installed only in slot 11 of the base cabinet (see
to install the
RSIU PCB).
2. A PDKU or PEKU PCB must be installed in slot 12 of the base cabinet to support the
programming telephone.
3. The first 8-station ports (000-007) appear on the PDKU or PEKU as installed in slot 12. The
programming telephone will then be on the 6th circuit (port 005; or, 013 until Program 03
Code 49 is set for slot 11) of the PDKU in slot 12.
The function and bit-per-second (bps) data rate of the RSIU or RMDS, RS-232 circuit port is
set in Program 76 as described in the
Strata DK Programming Manual.
All information provided in the
applies to installing an RSIU in
an existing system. Hence, most PCBs must be moved to the next highest slot.
