All configurations use an MCBH8M connector for input power and real-time connection to a host computer.  In addition there are 3 instrument-port configurations available:

• One segmented connector—6 ports 
• Two segmented connectors—12 ports (diagram)
• Up to 12 individual connectors—multiple ports per connector are possible, for more than 12 instruments (diagram)
• Custom housings can be tailored to your needs

• Baseline: 3 RS-232 ports 
• Expandable to 7 or 11 ports
• All ports bidirectional and simultaneously available
• RS485 available 

• Baseline: 4, 12-bit, 0 to 5V inputs
• Expanded: 16, 16-bit -8 to +8V inputs
• Inputs may be used in pairs for differential readings

HydroDAS provides up to 12 switched power outputs for external instruments, and may be configured for one of three input voltage options:

• Baseline: 7 to 18V input, outputs unregulated
• 60 V input, 12 to 15V regulated output
• 300 V input, 12 to 15V regulated output

Multiplexed data and commands travel to and from the host computer (if one is used) via one of the following interface options:

• Baseline: RS-232 (for short cables)
• RS-485 (for cables up to 500 - 1000 meters)
• 2-wire interface for cables up to 6000 meters (high voltage power sent on the same 2 conductors as the data)

Some combinations of power input and host data interface cannot be supported, and some require a deck unit.

	Power Input
Host Data	12 V	60 V, 1.0 A	60 V, 2.3 A	300 V
RS-232	OK	—	—	—
RS-485	OK	OK, deck unit required	OK, deck unit required	OK, deck unit required
2-Wire	—	OK, deck unit required	—	OK, deck unit required

• USB data offload is also available in custom systems.

A deck unit is not required for the baseline configuration, but is required for any high-voltage option.  See the table above.

For special applications, HydroDAS also includes

• up to 8 discrete digital inputs
• up to 8 discrete digital outputs
• up to 4 frequency inputs

• 128 MB flash standard 
• Up to 2 GB available
• Hard disk available for custom configurations
