Rear Panel J5 Connector
Make analog interface connections via the rear panel 25-pin female DSUB connector
designated J5. To provide the lowest noise performance, we recommend you use
shielded-twisted pair wiring for making connections from external circuits to the J5
connector. Use the shortest leads possible. Ground the shield to pin 6 (auxiliary
ground) on the J5 connector or to the chassis via one of the J5 connector screws.
Note:In order to maintain isolation of power supply output, any programming
source must also be an isolated source.
