Micro™ DPMs and counters offer RS232 or RS485 communication boards to interface with computers, PLCs or other digital devices, including the Micro 6-digit remote display. Both boards are connected via phone jacks using standard 4- or 6-conductor phone cables. With either board, Electro-Numerics provides Windows-compatible software which allows device setup via a computer monitor.
With DPMs and counters, the information transmitted via RS232 or RS485 includes the latest signal value (filtered or unfiltered), peak signal value, alarm values and status. By using a serial interface board, a Micro counter can be used as a remote display to an external device or to another Micro.

The RS232 option allows a Micro meter or counter to be programmed by a computer, to output data to a computer, or to drive a panel-mount printer, remote display, or other digital device with an RS232 interface. There can normally only be one meter or counter per RS232 line. However, multiple remote displays can be connected to a single RS232 line in multidrop fashion.
The RS232 request-to-send line (RTS) can be set to a latched mode, where a single reading is transmitted when the line is taken high. This mode allows a single data transfer to be commanded by a device other than a computer.
