Your remote modem connects to a LAPB Module in the system cabinet. The 28i
uses the LAPB P/N 92706 and the 124i uses P/N 92008. The LAPB Module is a
daughter board that plugs in the CPRU PCB. Using one of the cable sets listed
below, these modules allow you to connect to a local PC or a remote modem allow-
ing you to program the system.
28i PC Programming Cable Sets
For local PC connections, use DB9-to-8-Pin Cable Set (P/N 92708-DB9).
This cable set consists of the following two components:
8-Pin Circular Mini-DIN to Mod-8 Cable (P/N 92707A)
This 10' long cable has an 8-pin right angle connector on one end (for connect-
ing to the LAPB) and a standard 8-pin modular plug on the other end.
DB9-to-Mod-8 Adaptor (P/N 85980)
One end of this adaptor accepts an 8-pin modular plug. The other end is a stan-
dard DB9 female connector that you can plug into a 9-pin RS232 (DTE) port on
your PC or laptop.
For modem connections, use DB25-to-8-Pin Cable Set (P/N 92708-DB25).
This cable set consists of the following two components:
8-Pin Circular Mini-DIN to Mod-8 Cable (P/N 92707A)
This 10' long cable has an 8-pin right angle connector on one end (for connect-
ing to the LAPB) and a standard 8-pin modular plug on the other end.
DB25-to-Mod-8 Adaptor (P/N 85981)
One end of this adaptor accepts an 8-pin modular plug. The other end is a stan-
dard DB25 male connector. This connector is plugged into the DB25 female
connector on the cable that ships with the CNet modem. The 9-pin male connec-
tor on the CNet modem cable is then plugged into the DCE port of the modem.
