Front Panel Operation & Display
Multichannel Configuration
Channel Selection
By pressing the top button the instrument display switches to the next channel, it will
loop at the last channel to the first channel. Similarly the bottom button switches the
instrument to the previous channel.
Some systems may have other push button features. In this case, the left and right
arrow buttons indicate previous and next channel. Also the two push buttons above the
left and right arrow buttons switch between rows. For example, for a 48-channel system
set to Channel 1 would move to channel 13 if the “next row” push button was pressed.
Similarly, if the “previous row” push button was pressed, it will move to Channel 37.

Front Panel Operation & Display
Bidirectional Configuration
Mode Selection
Both push buttons allow the user to toggle between crossed mode or bar mode.
Bar Mode: This option is used for forward unidirectional testing. At this mode, the
Source port is connected to port 1, which outputs to port 2 and then to the OPM port.
Crossed Mode: Switching to crossed mode allows for testing in the reverse direction of
the cable without flopping. At this mode, the Source port reroutes to port 2 and outputs
to port 1, then eventually to the OPM port.
