Memory Cards The following characteristics are required of memory cards you intend to use
with the monitor:
•
Type 1 or Type 2 PCMCIA (68-pin) SRAM memory cards
•
Card sizes of .5 kilobytes and 1, 2, and 4 megabytes
•
Memory cards with 200 nanosecond (ns) speed ratings are desired
•
Some 250ns cards also work in the monitor. 250ns Epson and Mitsubishi
cards have been used successfully.
Note: 1 Meg memory cards are available through Ag Leader Technology.
GPS Receiver Almost all GPS receivers made for agriculture applications are compatible
with the yield monitor and thus meet the requirements listed below. Ag
Leader Technology sells a Coast Guard compatible receiver, the GPS 2000,
which can be used with the yield monitor. 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, Trimble AgGPS 120, 122 or
other high accuracy receiver that outputs the VTG data string, you can
obtain ground speed readings from the GPS signal.
