System Start-Up & Performance Check
With all optical and electrical connections made to both XMTR and RCVR modules, the green
LED on the front of each module displays status. Figure 7 illustrates the meaning of the
status LED for both XMTR and RCVR modules.
The status LEDs do not indicate if encoder signals are active. The system transmits exactly
what it sees at the inputs of the XMTR module. Best encoder wiring and cabling practices
must be followed to make sure that the encoder signal inputs are clean and properly
grounded. Signal integrity should be verified with an oscilloscope.
