3.3.10 SETTING MAIN CHANNEL MODE (VOLTAGE OR CURRENT)
When the unit is turned on, the main channel mode is determined by the power-up switches.
• If S3 is set to 00000 the mode is determined by the status of pin 2 of the Analog I/O port
(see Table 2-11). Applying a TTL logic 1 (or open circuit) programs the unit to voltage
mode. Applying a TTL logic 0 (or short circuit) programs the unit to current mode.
• If S3 is set to 0nnnn (where nnnn = binary number from 1 (0001, where S3-1 = 1) to 15
(1111), unit turns on with the mode previously saved in the selected location, and may be
either voltage or current mode.
• If S3 is set to 1xxxn (xxx = set as desired; if n = 0, unit is set to current mode, if n = 1, unit
is set to voltage mode.
Once the unit is powered up, main channel mode can be controlled by the FUNC:MODE com-
mand (see PAR. B.45).
• Sending FUNC:MODE VOLT sets the unit to voltage mode and sending FUNC:MODE
CURR sets the unit to current mode.
• Sending FUNC:MODE EXT allows the mode to be determined by the status of pin 2 of
the Analog I/O port (see Table 2-11).
3.3.11 PROTECTION LIMITS
When the unit is turned on the protection limits are determined by the power-up switches:
• If S3 is set to 00000 the protection limits are controlled by the pins 5, 6, 13 and 14 of the
Analog I/O port (see Table 2-11).
• If S3 is set to 100xx (x = set as desired, S3-3 and S3-4 = 0, S3-5 = 1), the protection lim-
its are controlled by the pins 5, 6, 13 and 14 of the Analog I/O port (see Table 2-11).
• If S3 is set to 0nnnn (where nnnn = binary number from 1 (0001, where S3-1 = 1) to 15
(1111), unit turns on with the limits previously saved in the selected location.
