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 clock.

To set the time zone adjust feature:

1. Decide which time zone(s) you are going to display. Figure out how many hours

ahead (+) or behind (-) the time zones are from your current time. This is the

number of offset hours. Use the DIP Switch Settings table below to determine the

correct switch settings for switches numbered 1-4 and 7. For example, if you are in

the Central Time Zone and you wish to display the time in the Eastern Time Zone,

the offset hours would be “+1”. The switch settings would be:

DIP 1=ON

DIP 2=OFF

DIP 3=OFF

DIP 4=OFF

DIP 7=OFF

2. Unplug the adapter from the wall outlet.

3. Use a Phillips screwdriver to remove the back plate from the serial clock.

4. Locate the DIP switches numbered 1-4 and 7. (See Figure 3:

DIP Switches 1-4 and 7).

5. Use the tip of a pen or small screwdriver to turn the DIP

switches on or off as directed by the table below.

6. Reattach the back plate and plug the adapter back into the

wall outlet.

NOTE: If you have a network of all clocks, one

clock must be set to master mode. All the

other clocks on the network must be set to slave mode. If

your network is connected to a PC, all clocks on the network

must be connected to the slave mode. (See Setting the #5 DIP

switch on page 10 for more information.
