Installing the SDI cable
To install the SDI cable, refer to “Connecting SDI ports on the SSC card” on
page 129 .
Installing the RSM Assembly Module
To install the RSM Assembly Module refer to page 196 .
Installing hospitality peripherals
A hospitality system requires you to connect two peripherals to the Option
11C Compact cabinet: a guest administration console (GAC) and the hotel’s
PMS. The RSM Assembly Module offers you two ways of doing this: using
RS-232 cables connected to the ports labelled P2, P3, and P4 on the assembly;
or using a single MDF cable connecting the port labelled P5 to a BIX or
similar modular distribution frame.
If you choose to use any peripheral cables exceeding 50 feet in length, short
haul modems are required. Inmac asynchronous line drivers (#8125) are
recommended.
1 Determine whether the hotel’s PMS is configured as data
communications equipment (DCE) or data terminal equipment (DTE).
Refer to the documentation for the product.
2 Locate the three-port SDI cable connected to the back plane of the
Option 11C Compact cabinet. Refer to
Figure 45 on page 205 .
3 Use a 0.5 ft. null-modem cable
(NTND93AA)
to connect Port 2 on the
three-port SDI cable
(NTBK48AA)
to P4 on the RSM Assembly Module.
4 Use a 10 ft. straight-through RS-232 cable
(NTND91AA or
customer-supplied equivalent
)
to connect P3 on the RSM Assembly
Module to the hotel’s PMS.
a If the PMS is configured as DCE, connect a null modem adaptor
(NTND93AA)
to one end of the cable.
CAUTION
Potential data loss
The connections from P5 are duplicates of those on P2, P3, and P4. Do
not use both sets of connections at the same time.
