Hi
Which port are you putting the commands into?
The box *may* respond to some things on the Diag port that it does not respond
to on the PPS port. I have not investigated this, but it is a possibility.

I now have my KS-24361 operating and I've successfully communicated via RS232

The time I'm getting out of the unit is the GPS time (+16 seconds). I've tried
to convert the time to UTC by first changing the mode from c
The rapid clicking of slave clocks in schools was a design feature of IBM (and
later Simplex) clocks. The master clock sent out minute pulses to the slave
clocks for the first 50 minutes of each hour on the "A" side of the circuit.
Slave clocks operating on-time would automatically switch to the
I have Arduino and Parallax BS2 programs that check the time from a Motorola
GPS card (UT) and then send out a pulse on an electronic relay once an hour.
The pulse starts at 59:57 past the hour and ends at 59:59. The solenoid
releases on each clock pretty close to the hour, and the clocks remain

Last year I picked up a frequency standard that inputs 120VAC (or 12V DC)
and drives a 6 0Hz Synchron motor based clock and also has a 120V 60 CPS

know I can run my old telechron synchronous clocks with this when the power
