DIG:DATA

This command sets and reads the power supply digital control port when that port is configured for Digital I/O operation.
Configuring of the port is done via an internal jumper (see Appendix D in the Operating Guide). The port has three signal
pins and a digital ground pin. Pins 1 and 2 are output pins controlled by bits 0 and 1. Pin 3 is controlled by bit 3 and can be
programmed to serve either as an input or an output. Pin 4 is the digital ground.
Bit position 2 normally serves as an output. To change it to an input, it must first be programmed high. The DIG:DATA?
query returns the last programmed value in bits 0 and 1 and the value read at pin 3 in bit 2. The bits are turned on and off in
straight binary code as follows:
