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.

The master/slave switch is located on the back of the clock, next to

the 12/24 hour switch (See Figure 1: Serial Clock—Rear Panel).

To change the master/slave mode settings, first remove the adapter

from the wall outlet, set the master/slave switch to the desired setting,

and re-insert the adapter into the wall outlet.

The slave mode setting can also be set using the #5 DIP switch. If the

#5 DIP switch is set to ON, the clock will operate in slave mode,

regardless of the setting of the master/slave switch. If the #5 DIP switch is

set to OFF, the clock will operate in the mode specified by the master/

slave switch on the back of the clock. This DIP switch capability is

provided in order to make it more difficult for unauthorized personnel to

change a clock from the slave mode to the master mode. (See Figure 6:

Setting the DIP Switches on page 10 for more information.)
