[DSP-10] GPS25-LVS Receiver

Sun, 28 Apr 2002 22:34:48 -0700

Darrel,
See section 4.1.3 of the manual:

The command is $PGRMC

send $PGRMCE    to get the current values.

you want to send back the same string with the item after the 12th comma = "2"
This turns on the
1PPS output
the value in the 13th position sets the length of the pulse from 20 to 980mSec.
0 = 20 mSec, 1 = 40mSec, 2 = 60mSec, ... 48 = 980mSec is the maximum allowed
value.

hope this helps,
Dan - W6LSN
