GPSConsole commands
IMPORTANT NOTES
Some features are available only on select models and firmware.
Commands beginning with “@” are sent to the receiver, while commands beginning
with “$” control gpsconsole itself.
4.1.1
@ANTENNA
Description:
@ANTENNA command selects which antenna input will be used by receiver. The
@ANTENNA command can also be used to test if an active antenna is connected by
running the command @ANTENNA ACTIVE TEST. This test will turn on the power to
antenna until after the next @START command. If the antenna is connected, then D1
should come on. If LED D1 does not light up, then try tightening up the antenna connector
or reattaching the antenna until D1 lights up.
Syntax:
@ANTENNA (ACTIVE | PASSIVE) [TEST]
Examples:
@ANTENNA ACTIVE
# Use active antenna
@ANTENNA ACTIVE TEST
# Test if active antenna is connected
4.1.2
@CHARGING
Description:
@CHARGING command sets the battery charging mode. If enabled and when the Stamp
Module is connected to Pin-4 (5V) of the PWR header (J4), the rechargeable battery will
be charged.
Syntax:
@CHARGING (ENABLE | DISABLE)
Example:
@CHARGING ENABLE
4.1.3
$DTR
Description:
$DTR command overrides the DTR pin on the FTDI board for GPIO testing. The
AUTOSLEEP option works with the WAKE pin (Pin-1 of the PGM/I2C header (J3)), when
“@WAKE ACTIVELOW” is set to enable the receiver to sleep, but wake up when
gpsconsole needs to send commands. If the DTR pin is not available, see $RTS.
Syntax:
$DTR (HIGH | LOW | PULSE | AUTOSLEEP)
Example:
