Installation
Status / Remote
The Status/Remote 9-pin D-connector on the rear panel allows remote monitoring of
status and remote control of the analog output level.
When monitoring status remotely, the front-panel controls continue to operate
normally, while the analog output level adjustments are disabled and can only be
adjusted by closing the remote switch. Please refer to the remote circuit example in
Figure 2-1.
NOTE: The output channel trims are adjustable when the remote level controller is
enabled. The Master Level cannot be adjusted.

NOTE: Pins 3 and 4 are internally shorted to detect CRC errors. CRC (Cyclical
Redundancy Checksum) verifies whether the transmission of data is error free or not.
When a CRC error is detected, it is added to the CRC log. The CRC log on the LCD
display is viewable when the DP562 is in Status mode (see Section 4.9, Status Mode).
