3.5" (8.89 cm) H x 19" (48.26 cm) W x 11" (27.94 cm) D
0° C to 50° C
16 inputs +/-4.5VDC maximum referenced to ground
16 inputs 0-28VDC or switch closure
32 open collector outputs (16 raise, 16 lower) maximum 250mA, 28V; 10 amp maximum with optional IP-8 interface panel. Configurable command duration from .22 to 28 seconds per channel.*
Failsafe & Alarm Outputs:
Open collector fail-safe output activates 90 seconds after detection of studio to transmitter link failure. Configurable alarm delay from 0 to 126 seconds per channel.*
Front Panel Controls:
Front panel selection of mode, maintenance override, channel increment, channel decrement, on/raise, off/lower, alarm clear.
Each channel is calibrated using the raise and lower keys to adjust the reading of the sample to the proper display value. The speed of the change in value is proportional, permitting ±1 digit adjustment or rapid gross changes.
Modem boards are installed for the class of service requested. A 2-wire modem is used for audio over a leased line or twisted pair. The Universal Modem provides independent path for send and receive, each configurable for audio, RS-232 or sub-carrier frequencies.
