3.5 ANALOG REMOTE PROGRAMMING
The ATE-DMG has the capability to control the output using external d-c analog reference volt-
ages. Analog references for both voltage and current are required to produce an output. Two
uncommitted amplifiers (preamps ”A” and “B”) included in the unit can be used for signal condi-
tioning. Each preamp has an inverting input (–), non-inverting input (+), and output, and a zero
adjustment, the preamps are accessible via A11J5 pins as shown in Figures 2-3 and 3-7 and
listed in Table 3-4. To gain access to A11J5, loosen two screws at the rear panel and disconnect
interconnection adapter A11, then remove two screws securing connector A11J1 to the shell.

(For further details about Preamp “A” and “B” go to www.kepcopower.com/support and down-
load the Operator manual for ATE 1/4 Rack, 1/2 Rack 3/4 Rack or Full Rack, and refer to PAR’s
3-37 through 3-84.)
Connections to A11J5 can be made via discrete wires, a flat ribbon cable not exceeding 1 foot in
length or by discrete wires terminated into crimp style pins inserted into a 5x2 housing (not sup-
plied). Recommended parts (ribbon cable, housing for discrete wires and pins) are listed as
accessories in Table 1-6).
NOTE: When making connections to A11J5, move unused jumper to a single pin of connector
J3 (DO NOT SHORT J3 PINS).
