RS-232C Command Set
Seconds Per Pulse / Pulse Per Hour
Command:
m,nPS
m,nPS configures the programmable pulse as “Seconds per Pulse” or “Pulse Per Hour” mode as follows:
Response:
C
Format:
m = 0, seconds-per-pulse mode
m = 1, pulse-per-hour mode
n = 1 - 60000 seconds if seconds-per-pulse mode
n = 0 - 3599 seconds offset from hour if pulse-per-hour mode
For the Seconds-Per-Pulse mode, the first pulse will be on time at the top of the minute. If n is divisible by
60, the first pulse will be on time at the top of the hour.
For the Pulse-Per-Hour mode, the pulse will be on time at the second after the hour described by n. For
example, 1,1200ps would cause a pulse at exactly 20 minutes after the hour.
If only one number is present then the number sets the seconds as in seconds-per-pulse mode.
Set Alarm Time Mark
Command:
ddd:hh:mm:ss(.ss)OU(OL)
OU sets the time at which the clock issues the programmable pulse, in the UTC timezone. OL sets the time
at which the clock issues the programmable pulse, in the Local timezone. If ddd is set to 0, the pulse will
repeat daily at the specified time. If ddd is set from 001 to 366, the output pulse will be generated at the
next occurrence of the specified time and date.
Response:
C
Format:
ddd = day of year (1 through 366)
hh = hour (0 through 23)
mm = minute (0 through 59)
ss = second (0 through 59)
(.ss) = fractional seconds in 0.01 increments (00 through 99)
OU = UTC time (OL for Local time)
Set Pulse Output to Slow Code
Command:
nCM
nCM configures the pulse output to slow code. Slow Code pulse output is held high and goes low for six
seconds on the day, four seconds on the hour and two seconds on the minute.
Response:
C
Format:
n = 0, Slow Code off
n = 1, UTC Slow Code
n = 2, Local Slow Code
Set Pulse Polarity
Command:
nPP
nPP sets the programmable pulse output polarity (i.e. TTL/CMOS high or low), where n = 0 sets pulse
polarity to positive, and n = 1 sets the pulse polarity to negative. Positive means that the output voltage is
held low until the beginning of the pulse period, at which time it goes high. Negative means that the output
voltage is held high until the beginning of the pulse period, at which time it goes low.
Response:
C
