Installation
E.Connecting the Repeater to a Laptop
NOTE: If connecting the repeater to a laptop, a terminating resistor must be used. Refer to the section on “Interfacing a Laptop to Machines” on page 5. Refer to Figure 9.
F. Tests
Once the network has been wired, run the following tests to ensure proper installation.
1.Power off all machines before test.
2.Check for continuity of 2 wires running from the central PC.
a.Disconnect the wires from the PC
b.Check for 120 Ω ± 20%. A much higher reading indicates an open circuit. This is caused by a break in the network. A much lower reading indicates a short in the network, which means the network is only communicating to a certain point in the network.
