Installing the Data Analyzer

Installing Analyzer Y-Cables

NOTE Cable installation is NO T required when using the Data Analyzer with

4-Channel (Z7300A) and 8-Channel (Z7340A) PCI ACC Multiplexer

products.

The analyzer Y-cable(s) must be installed to the appropriate port on the

ACC multiplexer breakout panel for either external or internal X.25

links. If you are running multiple concurrent analyzer sessions on

8-channel NIO or EISA multiplexer cards, all cables must be installed.

The cables are designed so that an internal ACC-based X.25 port on an

8-Channel device can be monitored by the analyzer from two of the other

ports on the same breakout panel. This configuration is shown in the

lower diagram in Figure 2-1 on page 21, and applies to 8-channel

multiplexers only. In this figure, the ACC-based X.25 connection is on

port0andtheanalyzerisonports1and2.

The upper diagram in Figure 2-1 shows the connection arrangement

when an external X.25 port is to be monitored. In this diagram, the

analyzer connections are made to ports 0 and 1. Note the labels on the

connectors and ensure the TX and RX connector positions correspond to

the DTE (TX) and DCE (RX) definitions in the network configuration file

(ttgen file). These details are described in “Configuring the Analyzer” on

page 27.
