ALPHA Serial Clock Manual

Introduction
The Alpha
®
serial clock displays the time in either 12-hour or 24-hour
mode using a 4-inch LED display. The clock can be used all by itself or it
can be networked with other Alpha
®
clocks or Alpha
®
signs. In a
network, one clock (or a PC attached to the network) is used to
synchronize all the other clocks to the same time.
Used by itself, the Alpha
®
serial clock should be set to master mode. In
a network composed of all Alpha
®
serial clocks, one clock should be set to
master mode and the other clocks set to slave mode. In a network with a
PC that is connected to Alpha
®
clocks and Alpha
®
signs, all the clocks
should be set to slave mode.
Power supply (AC adapter)
The clock is equipped with a small AC adapter with an 18-foot power
cord. Connect the power cord to the adapter plug receptacle on the
backside of the clock (See Figure 1: Serial Clock—Rear Panel) before
plugging the adapter into a standard 120V wall outlet.
