14 1 1 1 0 0 - 5V 76μV
15 1 1 1 1 0 - 2.5V 38μV

NOTE: Ranges 9 through 11 are identical to ranges 0 through 2.

Analog Output

Max Output Channels: 4
D/A Resolution: 12 bits (1/4096 of full-scale)
Data range: 0 to 4095 for all voltage ranges
Bipolar Output Ranges: ±10V
Unipolar Output Ranges: 0-10V

Digital I/O

Max Ports: 3, bi-directional, programmable in 8-bit groups, TTL-compatible, similar to 82C55 Digital I/O ports on Prometheus require direction to be set with dscDIOSetConfig() before use.

All DIO lines power-up in input mode and have readback capability.
All DIO lines have 4.7K Ohm pull resistors that can be configured for all pull-up or all pull-down with a jumper.
