Installing Analyzer Y-Cables

	NOTE: Cable installation is NOT 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 “Possible Y-cable Configurations”, and applies to 8-channel multiplexers only. In this figure, the ACC-based X.25 connection is on port 0 and the analyzer is on ports 1 and 2.

The upper diagram in Figure 2-1 “Possible Y-cable Configurations” 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”.
