TECHNICAL REFERENCE MANUAL
INTRODUCTION
Congratulations on the purchase of your Prairie Precision JDM-150 Modem. The JDM-150 RTK
Modem represents the third generation of RTK Network communications devices allowing the
John Deere SF3000 receiver to easily and reliably connect to any internet GPS/GNSS Corrections
source all the while being managed remotely without any interaction required on the end-users
part.
The goal of this manual is to provide technical information as well as an installation guide to aid
you with the start up of your PPN Network RTK system.
If you have any further questions to this guide please contact your local PPN reseller for further
information.

UNIQUE FEATURES
• Integrated 2G/3G Cellular Modem able to roam on any HSPA, GSM or CDMA
capable network
• Communications pecking order, which intelligently and automatically scans looking
for RTK Corrections from Cellular networks, Wi-Fi, and 900 MHz
• Remotely monitor and reconfigure while device is in operation through our online
admin tool as well supports'local'configuration via RS-232 serial port commands.
• Standard RS232 port for easy cable setup and prototyping
• Cached GPS positions allows the JDM-150 to function without position from internal
GPS receiver improving its robustness over older generation RTK Bridges
• High performance integrated aGPS receiver (no external cables required) that will
typically achieve a positional fix in under 10 seconds
• Integrated 900 MHz radio (optional) for signal repeating to slave JDM-150 Modem
systems
• Creates an automatic Wi-Fi hotspot when connected to your cellular carrier for use by
other Wi-Fi enabled devices.
