Enclosure Considerations

A desiccated, non-condensing environment is required. The MD485 includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.

Combining with Other Devices

The MD485 can be combined with our AVW200-series Vibrating Wire Interfaces, CC640 Digital Camera, Ethernet links, phone modems (including cellular), and spread spectrum radios. Field site equipment should be housed in an environmental enclosure. Information about configuring the other devices is provided in the user manuals.

Power Considerations

AC power is typically used at the computer site; a #15966 wall charger is required. At the field site, the MD485 is powered by the datalogger through its CS I/O port. If the MD485 is connected to the datalogger’s RS-232 port instead of the CS I/O port, or if the datalogger was purchased before 12/97, a #14291 Field Power Cable is required. Phone-to-MD485 and spread spectrum radio-to-MD485 networks also require a power supply with a null modem port. An A100 adapter used with a PS100 or PS200 power supply provides this capability. The PS100 or PS200 is recharged via a wall charger or a solar panel.
