Requirements
The following characteristics are required of memory cards you intend to
use with the monitor:
Card Type Sizes Specifications (all cards)
SANDISK ATA
Flash card
2 to 32 megabytes (max)
Type 1 or 2 PCMCIA
68-pin connection
200 ns speed rating
IMPORTANT: ATA Flash cards are the only brand of ATA Flash
cards that are guaranteed to work in the PF3000.
Note: 32 MB SANDISK ATA Flash cards are available from your Ag
Leader Technology dealer.
GPS Receiver
Almost all GPS receivers made for agriculture applications are compatible
with the PF3000 and thus meet the requirements listed below. Ag Leader
Technology sells a Coast Guard compatible receiver, the GPS 3000 and also
a machined Coast Guard and satellite differential compatible receiver, the
GPS3100 and GSP 4100 with satellite differential and WAAS capability.
The GPS receiver must be configured to send GPS data according to the
following parameters:
• NMEA standard data output protocol
• 4800-X-8-1 communications protocol
• GGA data string—the only data string needed
• Send all messages once per second.
NOTE: If you use the Ag Leader GPS 2000/2100, Add-On GPS 3000/3100,
Trimble AgGPS 120, 122, 132 or other high accuracy receiver that outputs
the VTG data string, you can obtain ground speed readings from the GPS
signal.
