The RCI-200-MDM is a bi-directional dial-up communication system that exchanges the status of 2 dry contact inputs and 2 analog inputs between a host and remote unit or a PC equipped with a modem. A basic system consists of A) one host station and one or more remote station(s) OR B) several remote stations and one PC with a modem.

In system A), the host unit can be set to interrogate the remote unit(s) periodically or when required. Remote units may also be configured to call the host when required. One host may operate several remote units.

In system B), a PC can call several remote units or alternately, remote units may call the PC when required

LabVIEW drivers are provided for user software development on PCs.
