RS-232C Command Set
Seconds Per Pulse / Pulse Per Hour
Command:
m,nPS
Configures the programmable pulse as “Seconds per Pulse” or “Pulse Per Hour” mode.
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

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. If Pulse-Per-Hour mode, the pulse will be on time at the second after the hour
described by n. For example: 1,1200PS will generate a pulse at exactly 20 minutes after the hour.
Set Alarm Time Mark
Command:
ddd:hh:mm:ss(.ss)OU(OL)
Sets the time at which the clock issues the programmable pulse. 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.
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 (OL for Local time)

Set Pulse Output to Slow Code
Command:
nCM
Configures the slow code pulse output. Held high and goes low for two seconds on the minute and four
seconds on the hour.
Format:
n = 0 Slow Code off
n = 1 UTC Slow Code
n = 2 Local Slow Code
Response:
<
CR

Set Pulse Polarity
Command:
nPP
Sets the programmable pulse output polarity. 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.
Format:
n = polarity: 0 = positive 1 = negative

Set System Delay
Command:
nnnnnnDA
Sets the system delay compensation value. See Section 4.4.1 for information on calculating cable delay.
Format:
nnnnnn = delay: 0 0 ns to 999 999 ns
