74 Serial Communication and Command Set
xPM activates (x = 1) or deactivates (x = 0) the use of the main serial port, pin 6 controlling
(by high or low input) the output from pin 3. When used with a modem, the modem can be
programmed to toggle HI and LO to effectively free it from domination from a broadcast output
from the clock and restore operation.
Normally, pin 6 is not used to control any communications in the clock. The default setup when
shipped from the factory turns OFF this feature. To enable this feature, and halt the transmit
output from the UART to the serial port connector (pin 3), send a 1PM. When the broadcast
control is enabled and pin 6 is pulled LO, the transmitted output will stop. When broadcast
control is enabled and pin 6 is pulled HI, the transmitted output will continue from the serial port.

10.2.4 Event Mode Commands
Return Specific Event
Command: nnnA
nnnA sets the event buffer read index to a specific event number (001 to 400), and returns that
event information in either Local or UTC time format depending on how the command, nTA is
configured.
Response: LCL mm/dd/yyyy hh:mm:ss.sssssss nnnL
C
UTC mm/dd/yyyy hh:mm:ss.sssssss nnnU
C
Format: nnn = Event–Buffer Read Index Number
U = UTC Time
L = Local Time
Set Event Channel Time
Command: nTA
nTA sets the time source as either Local or UTC, where n = 0 sets the event time to UTC and n
= 1 sets the event time to Local.
Response:
C
