12.2 Pulse Outputs
12.2.1 1PPS Output
GPS Master Clock Model MC-1-M device provides 1PPS output at every 1 second through its BNC
terminal on rear panel of unit. This is TTL signal of 0(low level) to 5V (high level) value. The Pulse width of
1PPS signal is 20% duty cycle i.e. 200 milliseconds (high level) and 800 milliseconds (low level).
12.2.2 Event Output (PPM/PPH)
GPS Master Clock Model MC-1-M device is equipped with the standard feature of providing event output
at every PPM (Pulse per Minute) / PPH (Pulse per Hour) with fix pulse width of 1 second. This event
provides pulse output according to configured time interval i.e. Minute / Hour through front panel keypad
or COM2 terminal on back panel. Please refer section 8 for method of configure standard event output
through serial and section 10.2.6 to configure through keypad on device. Refer technical specification
section 4 for electrical characteristics of event output.
12.2.3 Additional Event Outputs (Programmable Pulse Outputs)
GPS Master Clock Model MC-1-M device is equipped with the (optional) feature of providing 1 to 4
additional event outputs. These events provide pulse output according to configured time interval and ON
time. Each event time can be configured with time interval ranging from 1 sec to 86400 seconds and
pulse ON time (pulse width) from min. 50 milliseconds to max. 50% of configure time interval of that
particular event in terms of milliseconds through front panel keypad or COM2 terminal on back panel.
Please refer section 10.2.7 for method of configure additional event outputs through serial and section 8
to configure additional event outputs through keypad on device. Refer technical specification section 4 for
electrical characteristics of additional event outputs.
