CAUTION Do not touch the probe connector pins or the cable connector pins. Static
discharge may damage equipment.
Connecting to 10MB/s Ethernet Telemetry Networks
You can connect the probe to the network either by connecting the RJ-45
connector to a 10Base-T/100Base-TX half-duplex network or by connecting the
AUI connector to a 10MB/s Ethernet network. Use the following procedures to
connect the probe’s AUI connector to a 10MB/s Ethernet network for telemetry
communications. Never use both the AUI and RJ-45 connectors.
1. Connect the probe’s AUI port, located on the rear panel , to the net work wit h
an AUI cable. Figure 3-4 shows how to connect the probe to a 10MB/s
Ethernet network using the AUI connector.
2. Select AUI as the Physical Connector parameter from the Modify/View
Interface Values menu. Refer to Step 1 on page 25 for information on
configuring the Physical Connector parameter.
