TABLE 2-7. ANALOG I/O CONNECTOR (J2) PIN ASSIGNMENTS
PIN SIGNAL NAME FUNCTION
1 Cref Analog signal which programs output current from zero to full scale. Voltage or resistance programming
is selected via DIP switch position 2 (See Table 2-2). Refer to PAR. 3.4.2 for voltage programming and
3.4.1 for resistance programming.
2 RELAY_NO Connected to RELAY_COM (pin 4) for relay energized condition. (1)
3 Vref Analog signal which programs output voltage from zero to full scale. Voltage or resistance program-
ming is selected via DIP switch position 1 (See Table 2-2). Refer to PAR. 3.4.2 for voltage programming
and 3.4.1 for resistance programming.
4 RELAY_COM Relay common. (1)
5 Reserved.
6 VOLT_RBACK Analog signal which represents output voltage from zero to full scale (see PAR. 3.4).
7 CURR_RBACK Analog signal which represents output current from zero to full scale (see PAR. 3.4).
8 REM_INH Allows single signal to control output on/off. See PAR. 3.2.6.
9 GND Ground
(2)
10 RELAY_NC Connected to RELAY_COM (pin 4) for relay not energized condition (1)
11 GND Ground
12 ANALOG_CTRL Enables or disables analog programming (see PAR. 3.4).
1 = Analog programming disabled (default, no connection)
0 = Analog programming accepted (use jumper on mating connector to connect to pin 9, 11, 13 or 15
(ground).
13 GND Ground
14 EXT_TRG Performs same function as SCPI *TRG command if unit is programmed for external triggering via digital
remote mode. Transition from 1 (+5V) to 0 (ground) causes values established by VOLT:TRIG and
CURR:TRIG commands to become unit setpoints (see PAR 3.3.2, External Triggering).
15 GND Ground
(1) Refer to PAR. 3.2.17.1 to configure internal relay.
(2) All GND connections are common.
