Overview
The ANC-7020 series large format synchronous clock display decodes an
RS485 or RS422 noise immune serial signal to remotely display time-of-day
information.
Mechanical Specifications
Clock case size:
5.0"H X 13.5"W
Clock display size: 4.0”H X 11.5”W
Weight:
2 pounds
Connectors:
6-pin RJ-11 modular phone jack with loop through
2.1mm Barrel connector for +5V DC power to unit (center pos.)
Electrical Specifications
Power requirements = 180 ma for full brightness and all LEDs on
150 ma for display at full brightness and normal time display
30 ma for display at dimmest setting and normal time display
20 ma for display off (0/16 brightness setting)
RS-422/485 input = short proof input, non-terminated operation to 150 feet,
terminated operation to 4,000 feet.
Installation
Turn off the ANC-7030 controller chassis before connecting the clock or external
power is connected to the clock display.
Never install or remove the clock display
with the power applied to the controller chassis or any other attached clock or
equipment. This could result in permanent damage to the clock due to static
discharge.
Normally the clock is plugged directly into the serial port RJ-11 converter
adapter which plugs into the male DB-9 jack on the back of the chassis under the
connector labeled "CLOCK. The RJ-11 to male DB-9 converter would be impossible to
plug in to the wrong DB-9 (marquee DB-9 connector is female), but the marquee and
clock connectors are both RJ-11s. The user should screw the 2 mounting screws into
the serial port’s DB-9 hex nuts for permanent installation to assure good long-term
connection
