EMI Compliance The Alpha serial clock complies with Part 15 of the FCC Rules. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These are limits designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
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.
ALPHA Serial Clock Manual Master/Slave modes The Alpha serial clock can either operate in master or slave mode. A clock set to master mode sends out the time once each minute to all of the other clocks on a network. A clock set to slave mode is ready to receive the time from the master clock or a PC (personal computer). On a network, only one clock should be set to master—all other clocks should be set to slave mode. On a network attached to a PC, all clocks should be set to slave mode.
ALPHA Serial Clock Manual Setting the time HOUR Button MINUTE Button Figure 2: Serial Clock—Front Panel To set the time of the master clock, use the HOUR or MINUTE buttons on the front lower right side of the clock (See Figure 2: Serial Clock—Front Panel). The HOUR and MINUTE buttons do not operate if the clock is set to slave mode. To set the hours, press the HOUR button until the desired number is displayed. There is no AM/PM option.
ALPHA Serial Clock Manual Network configurations—Adding serial clocks to an Alpha network Alpha serial clocks can be connected together with each other or in a mix of Alpha signs. Also, like an Alpha sign, an Alpha serial clock must be terminated when it is the last device on a network. In a network, one clock (or a PC attached to the network) is used to synchronize all the other clocks to the same time.
ALPHA Serial Clock Manual Table 2: Networking Alpha serial clocks (Example 2 — A RS485 network of all clocks) In this example of an all-clock RS485 network, one of the clocks must be set to master mode. All the other clocks on the network must be set to slave mode. Also, the first and last clocks on the network must be terminated.
ALPHA Serial Clock Manual In a network with a PC that is connected to Alpha clocks and Alpha signs, all the clocks must be set to slave mode. Table 3: Networking Alpha serial clocks (Example 3 — A network of clocks attached to a PC) Unlike the previous all-clock network, in this example, a PC is connected to the network. All the clocks on the network must be set to slave mode. Also, the last clock on the network must be terminated.
ALPHA Serial Clock Manual Time zone adjust feature Some Alpha serial clocks have a time zone adjust feature. This lets you display the time in different time zones on your networked clocks. For example, you could network four clocks in an office and use them to show the time across the continental United States. Clocks with this feature do not have the ability to set a serial address. This feature may not be available on all Alpha serial clocks. To set the time zone adjust feature: 1.

ALPHA Serial Clock Manual Wall mounting Plate is flush with backside of clock—”feet” are hidden. Plate is reversed—”feet” are facing out. Wall Mounting Countertop Mounting Figure 4: Serial Clock—Side View 1. Locate the keyhole slots on the back of the clock, at either end. The slots are placed six inches apart (See Figure 1: Serial Clock—Rear Panel on page 7). 2. Install two #8 screws into the wall/mounting surface, six inches apart.

To change the #5 DIP switch settings: 1. Unplug the adapter from the wall outlet. 2. Use a Phillips screwdriver to remove the back plate from the serial clock. 3. Locate the #5 DIP switch (See Figure 6: Setting the DIP Switches). 4.
