GPS Antenna (AGI−4)
The GPS antenna assembly is mounted to the machine
ROPS. Unswitched power is provided to the antenna as
long as the battery cables are connected to the battery.
A 10 amp fuse provides circuit protection for the
unswitched power to the antenna. A switched power cir-
cuit is also required to operate the antenna.
The AGI−4 antenna, X25 or X30 control console and
ASC−10 auto section controller communicate with each
other on a CAN−bus network. The GeoLink Can−bus
network is separate from the sprayer traction unit CAN−
bus.
NOTE: The AGI−4 antenna may include a cellular mo-
dem and IMU for machines with RTK correction.
Minimum voltage requirement: 5.5 VDC.
Diagnostic LEDs
PWR: power supply status (steady green = OK)
STAT: satellite and receiver status (flashing red = no
satellites, flashing yellow or green = satellites OK)
RX/TX: modem status (flashing green = receiving
position correction information)
SYSFIX: record and data status (flashing green =
correction information processed and position es-
tablished)
Connections
Coaxial connector for cellular antenna (machines
with RTK correction only)
12 pin harness connection (black)
12 pin harness connection (gray)
Coaxial connector for external GPS antenna (not
used)
A pair of similar twelve (12) pin connectors are used at
the GPS antenna. The layout of the wire harness con-
nectors is shown (Fig. 59). See the electrical schematics
and wire harness drawings and diagrams in Chapter 11
− Foldout Drawings in this manual for additional infor-
mation.

NOTE: The ASC−10, the X25 or X30 control console,
the GPS antenna assembly (including the modem and
the IMU for machines with RTK correction) are pro-
grammed specifically for each sprayer. If any of these
components require replacement for any reason, con-
tact the National Service Network (NSN) or your Toro
Distributor. The replacement components provided
should arrive pre−programmed for the specific sprayer.
