B.5.2.3 MASTER
When several displays are connected in a network, only one can be the time Master. The Master
transmits time messages to all other displays on the network. Turning Master OFF inhibits the display
from transmitting time messages. The message format is:
MASTER x
where x is 0 (Master off) or 1 (Master on).
B.5.2.4 SET REAL TIME CLOCK
To set the internal clock of the bc632D, use this command:
TIME hh:mm:ss MM/dd/yy w
Where:
hh is the hours.
mm is minutes.
ss is seconds.
MM is month.
dd is day of month.
yy is year.
w is day of week (1=Monday, 7=Sunday).
Use leading zeros if necessary. For Example, 1:00:00 am, February 3, 1992, Monday, would be sent
as:
TIME 01:00:00 02/03/92 1.
