4.2 CONFIGURING FOR REMOTE PROGRAMMING,
SENSING, AND MONITORING
This section lists switch, connector, and jumper functions for the DCS-E Series (3kW) supply.
Subsequently, it provides a location diagram (Section 4.2.2), in addition to procedures for
resetting the internal jumpers and switches (Section 4.2.3), and for reconfiguring or making
connections to the J3 connector (Section 4.2.4).
You will find remote programming procedures and diagrams covered in more detail in
Section 4.3, remote sensing in Section 3.3, and remote monitoring of readback signals and
status indicators in Section 4.6.

You can use the REM/LOC (Remote/Local Programming) switch for remote programming.
When set to REM (Remote Programming), control of BOTH output voltage AND current limit is
passed to external voltage and/or current sources which are connected to the J3 connector.
Resetting the switch to LOC returns the supply to local (front panel) control. See Section 4.3
for more information about using this switch.

The external J3 connector provides user access to the following functions:
•
Remote programming of output voltage OR current limit, and for OVP
•
Remote monitoring of the following readback signals and status indicators
Readback Signals Status Indicators
Calibrated output voltage
Thermal shutdown
Calibrated output current
OVP circuit
Remote/local programming mode
•
Remote programming of the shutdown function using AC, DC, or TTL compatible
signals
•
Remote sensing of output voltage
See Figure 4-1 Connector J3.
WARNING!
Use extreme caution when biasing the output relative to the chassis due to
potential high voltage levels at the output and J3 terminals.
