Port Definitions
Each port on each multiplexer card to be used for the D ata Analyzer
must be correctly configured to support the Frame capture firmware
protocol. In the 8-channel sample shown below, ports 2 to 7 on mux 0
are used for analyzer ports. Note the following configuration
requirements:
• Select the correct mux and port for each analyzer connection.
• Set RS232 mode for both RS-232 and V.35 analyzer ports.
• The baud rate is not important but set for an expected nominal rate
(57600 chosen here).
• The Clocking option must be set to Ext.
• The Mode, clock multiplier, and encoding must be set to SDLC, x1,
andNRZ.IfNRZIencodingisusedsetthistoNRZIinstead.

connection that is looped back between these ports. Use the loopback
cable supplied with the selected ACC interface panel to connect these
ports (see Figure B-1). Ensure the end marked Internal is connected to
port0,andtheendmarkedExternal is connected as described below.
Connect the Y-cable as shown. The connector designated “P2” on the
Y-cable g oes to the connector marked External on the loopback cable. See
also Appendix A , “Analyzer Cable Assemblies,” for more detailed
description of the Y-cable.
