TABLE 2-4. RS232 PORT CONNECTOR (J3) PIN ASSIGNMENTS
CONNECTOR PIN SIGNAL NAME FUNCTION
NOTE: A null modem cable (see Table 1-4) is required for nearly all applications, with the exception of those in which RXD and
TXD line transposition is accomplished via external hardware (e.g. older Apple MAC computers with D-sub serial port).

TABLE 2-6. 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. 3.7.3 for voltage programming and
3.7.2 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. 3.7.3 for voltage programming
and 3.7.2 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. The full scale programming level
sets the full scale readback level (see PAR. 4.3.3).
7 CURR_RBACK Analog signal which represents output current from zero to full scale. The full scale programming level
sets the full scale readback level (see PAR. 4.3.3).
8
REM_INH Allows single signal to control output on/off. See PAR. 3.7.1.
0 = Output is off
1 = Output is on (default, no connection)
9 GND Ground
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. 3.7).
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 via digital remote mode. Tran-
sition from 1 (+5V) to 0 (ground) causes values established by VTRIG and CTRIG commands to
become VSET and CSET (see PAR. 3.3.1.3).
15 GND Ground
(1) Internal relay may be configured to produce Fault signals at the users discretion. Refer to PAR. 3.2.11.3 to configure internal
relay.
