The R194 is an eight channel on-screen composite video text character
generator that can overlay characters onto program video during EAS alerts.
Alert audio also replaces program audio for each channel. Video loop-thru
connections are all BNC type. Audio loop-thru connections are all pluggable
screw terminals. Control is by standard RS-232 signaling using DB9 type
connectors. Up to 32 R194’s can be daisy-chained together to allow
EAS service to as many as 255 individual analog channels from a single
Monroe EAS controller.
