The UMC Modem card is the preferred method for reliable communications
between TouchStar™ Master Control Systems and remote site equipment.
It provides quick and flawless communication over RS-232/RS-422,
2 or 4 wire leased line and 2 wire dial-up. UMC Modem cards
can easily be reconfigured to work in any of these modes by
changing dipswitch settings on the face of the card.
