Serial Expansion Module

EMSP-1™ serial port expansion module can handle up to eight digital sensor connections.

Up to 16 ports can be supported by adding two modules on the sensor input (right) side of MDL-700.

  • Eight serial ports
  • Standard TTY access
  • Individually software selectable as RS-232 or RS-485
  • SDI-12 compatible ports
  • Software controlled bias and termination resistors
  • Regulated power source on each port
  • Discrete pluggable terminal connectors


MDL-700™ may be programmed to monitor a range of sensors and control outputs using available expansion boards. This makes the system adaptable for:

  • Environmental research
  • Remote site monitoring
  • Remote command and control
  • Process automation
  • Equipment testing
