D. Testing your TC3020 for performance will require the testing setup shown on Fig. 8 below. This test should
be done using your PC's hyperterminal. You will need to locate the DIP switches on the front panel of Unit B
and enable switch #1 (MM LB) to the "ON" position (as shown on figure 8.1) for this test.
1. Use an RS-232 adapter and connect it from your PC to a Single mode TC1200 fiber modem or a compatible
RS-232 fiber modem.
2. After completing all of the connections you should be able to transmit and receive data.
3. You should observe that the (MM TX), (MM RX), (SM TX), and (SM RX) LEDs on Unit A are lit solidly. You
should also observe that the (MM RX), (MM TX), and the (MM LB) LEDs are lit solidly on Unit B. This indi
cates that both of the units are working properly.
4. After you finish this test, reset switch #1 (MM LB) to the "OFF" position to perform the next test..
