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 pin6 (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.
