The RSIU is a standard plug-in type PCB that must be installed into the first universal slot of the
DK424 base cabinet. The RSIU PCB provides one standard RS-232 port (modular jack) when
ordered from the factory; this port can be configured in system programming to support any one of
the hardware options listed above.
The RSIU can be equipped with up to three more optional RS-232 ports (total of four RS-232
ports) or with two optional RS-232 ports and one modem port (total of three RS-232 ports and one
modem port). The optional RS-232 ports are provided by installing RSIS piggy-back PCBs onto
the RSIU PCB. The optional built-in modem is provided by installing an RMDS piggy-back PCB
onto the RSIU (see Figure 7-38 in Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring).
The RSIS PCB can support any one of the hardware devices listed above via its RS-232 modular
jack. The RMDS PCB can function two ways: the RMDS can operate like an RSIS allowing it to
support any one of the hardware devices listed above locally from its RS-232 modular jack; or, the
RMDS can operate as a 1200 bps (bits-per-second) or 2400 bps system remote maintenance
modem.
The RMDS PCB function (modem or RS-232 port) is set in a system program option. The RMDS
can be set for one function only; it cannot support both functions simultaneously. When configured
as a modem, the RMDS PCB supports only the DK424 remote maintenance, ASCII terminal, or
DKBackup, and DKAdmin functions, and does not simultaneously support SMDI, SMIS, SMDR,
etc. (See Figure 8-36 on Page
The total bits-per-second (bps) data rate of the four RSIU, RSIS, RMDS (RS-232/modem) ports
combined cannot exceed 9600 bps. The RSIU, RSIS RS-232 ports can be individually set in
system programming to operate at 1200 bps, 4 ports max.; 2400 bps, 3 ports max.; 4800 bps, 2
ports max.; or 9600 bps, 1 port max.; or, any other combination that does not exceed 9600 bps. The
RMDS modem function can be set to operate at 1200 bps or 2400 bps; however, if the RMDS port
is used as a RS-232 port instead of a modem, it can also be set for 4800 bps or 9600 bps.
The TTY and modem function cannot operate on separate RSIU, RSIS, RMDS ports
simultaneously. If both functions are programmed at the same time on separate ports, the function
of the lowest numbered RSIU, RSIS, RMDS port (TTY or modem) will be active.The
communication parameters for all RSIU, RSIS, RMDS port function types except the SMDR are:
Data word bits = 7
Parity = even
Stop bits = 1
The communication parameters for an RSIU, RSIS SMDR port is:
Data word bits = 8
