Maintenance and Testing
instrument will test cable continuity on all five XLR pins. Please refer to the
Li'l DMX'ter Operating Manual for more information.
.3 Other Test Equipment -- The maintenance technician will find the following
additional test equipment useful:
.1
Oscilloscope -- for viewing data in conjunction with the DMX'ter and
its scope trigger module; for checking that both differential signals are
present on a given data line; for evaluating the performance of
crosspoint matrix and opto-repeater circuitry at higher operating
speeds (greater than one million bits per second).
.2 Frequency Generator -- for testing crosspoint matrix and opto-
repeater high speed performance. Useful for evaluating whether
other systems with higher data rates can be used in the network.
.3
Digital Volt/Ohm Meter -- a general purpose tool for checking
continuity, termination resistor values and power supplies.
