Garmin 530 Port 5001 and the Garmin 430 Port 4001
Garmin 430/530(WAAS) pin # 56(tx) goes to EDM’s pin # 2(rx) or FS-450’s pin# 9(rx).
Garmin 430/530(WAAS) pin# 57(rx) to the EDM’s pin# 1(tx) or the FS-450 pin# 6(tx).
Programming the Garmin 430/530 and EDM/FS-450:
#1) Garmin program to: RS-232 Input Shadin FF and RS-232 Output Aviation Data formant. Since this Garmin input is now Shadin FF, then on both the EDM and FS-450 you must choose GPS-C=1. (Waypoint) You can not use GPS-C= 6 or 7. If you did you would get a ‘No RS-232 Data’ message on the Garmin.
#2) If you program the Garmin Input to Shadin FADC, (same Output –Aviation) then you will need to program the EDM and FS-450 to GPS-C= 6(waypoint) or 7 (destination). You can not use GPS-C=1 anymore. If you did you would get the ‘No RS-232 Data’ message on the Garmin.
See GNS 480 Installation Drawing RS-232 Interfaces Appendix D (D-11):
“Serial Port 1 (P1-4/5/23) or serial Port 5 (P5-1/21/41) may be used instead of serial Port 2 for F/ADC. GNS 480 RX serial port must be configured for FADC 9600 Baud. Transmit port must be configured for MAPCOM 9600 Baud.”
Set GNS 480 Port 2
MAP COM Output.
Input: FADC (9600 baud.).
Then set the EDM to GPS-C= 6(waypoint) or 7(destination)
Garmin 95XL is a portable GPS. Not designed to receive fuel flow data. 95XL pin #3 brown wire to pin#2(rx) on the EDM or pin# 9(rx) for the FS-450. The 95XL pin # 2 black wire MUST be connected to the same ground as the JPI. Only one wire used. No transmit(tx) connection from JPI to Garmin.
Program Garmin to NMEA 183 OUT. V2.0 (4800 baud rate) If the EDM or FS-450 senses NMEA-183 ‘Marine Navigation Data Format’ input, there will be no fuel data output(tx) to the GPS – so no ‘GPS-C’ setting needed for JPI units.
The Garmin 96/96C are portable GPS’s. As such are not designed to receive (rx) fuel flow data. Only one wire used to transmit data from the Garmin to the EDM/FS-450.
Garmin ‘Data Out’ pin # (see Garmin manual for #) to pin#2(rx) on the EDM or pin# 9(rx) for the FS-450.
The Garmin ground – black wire -MUST be connected to the same ground as the JPI. ** Again, only one wire is used. No transmit (tx) connection from JPI to the Garmin.
These Garmin’s can supply NMEA output to the fuel totalizer, but do not have a way to display any fuel flow information. Program the Garmin to NMEA 183 OUT. V2.30 (4800 baud rate) If the EDM or FS-450 senses NMEA-183- ‘Marine Navigation Data Format’ – input, there will be no fuel data output(tx) to the GPS – so no ‘GPS-C’ setting needed for JPI units.
Lowrance 2000c Data out to pin#2(rx) on the EDM or pin# 9(rx) for the FS-450. **Only one wire used. ** No transmit (tx) connection from JPI to GPS.
Program GPS to NMEA 183 OUT. (4800 baud rate) If the EDM or FS-450 senses NMEA-183 ‘Marine Navigation Data Format’ input, there will be no fuel data output (tx) to the GPS – so no ‘GPS-C’ setting needed for JPI units.
SkyForce pin# 11(tx) to the EDM’s pin # 2(rx) or FS-450’s pin# 9(rx).The SkyForce sends navigation data output to the EDM or FS-450, but they do not transmit any fuel data to the Skymap. So there is only one wire hookup – SkyForce tx to EDM or FS-450 rx only as above. Both instruments should be grounded at the same point.
To program the SkyForce, choose NMEA-183 (Marine Navigation Data Format) Baud rate 4,800. No programming of the EDM or FS-450. When these sense Northstar or NMEA-183 navigation data input, there will be no fuel data output.
Skymap pin# 2(tx) to the EDM’s pin # 2(rx) or FS-450’s pin# 9(rx).The Skymap sends navigation data output to the EDM or FS-450, but they do not transmit any fuel data to the Skymap. So there is only one wire hookup – Skymap tx to EDM or FS-450 rx only as above. Both instruments should be grounded at the same point.
To program the Skymap, choose NMEA-183 (Marine Navigation Data Format) Baud rate 4,800. No programming of the EDM or FS-450. When these sense Northstar or NMEA-183 navigation data input, there will be no fuel data output.

Garmin: Input: ‘Shadin FF’ Output: ‘Aviation’ – > EDM: GPS-C= 1
** (You can not use GPS-C= ‘6’ or ‘7’ if you choose ‘Shadin FF’ for the Garmin. If you do, you will get a ‘No RS-232 Data’ message on the GPS)
(Or)
Garmin: Input: ‘Shadin FADC’ Output: ‘Aviation’. – EDM: MUST use GPS-C= 6 or 7.
** (You can not use GPS-C= ‘1’ if you choose ‘Shadin FADC’ for the Garmin. If you do, you will get a ‘No RS-232 Data’ message on the GPS)
• NO – COM message and parameters REQ, RES, & MPG are missing., Communications are received by EDM and the Auto-Protocol setup is in process. Verify correct output format setup in GPS receiver; check GPS connections.
• NO – SIG message and parameters REQ, RES, & MPG are missing., GPS receiver has insufficient signal for valid data.
• NO – WPT message and parameters REQ & RES, are missing., No waypoints are programmed into the aircraft GPS receiver.
• – – – REQ or – – – RES message, Your ground track is more than ?70° from your course to the next GPS waypoint.
#1) If the GPS is sending NMEA-183 (not an aviation format – Marine Navigation Data Format – 4800 baud), the FS-450 or EDM-700 will sense this and there will be no fuel data output.
#2) Check that the baud rates are the same between input and output.
#3) Also program the EDM/FS and the Garmin correctly:
Garmin: Input: Shadin FF > then the EDM: GPS-C= 1
Output: Aviation Data Output
(or)
Garmin: Input: Shadin FADC > EDM: GPS-C= 6 or 7
Output: Aviation Data Output.
** (Can not use ‘1’ if you choose FADC for the Garmin – if you do you will get a ‘No RS-232 Data’ message on the GPS)
#4) Check for fluctuating voltage on the FS-450 or EDM fuel flow harness ‘Out to GPS’ wire. (Should see a -5v to -7v ‘burp’ type fluctuating voltage signal.)
FOR THE GX50/60/65:
FOR THE FS-450:
FOR THE EDM-700/800:
FOR THE EDM-900/930:
GX INPUT: SHADIN ‘S’ OUTPUT: AVIATION
FS-450 OR EDM/700/800/760: GPS-C=6 OR 7. ‘6’ IS TO WAYPOINT ONLY AND ‘7’ TO DESTINATION ONLY.
** NEW GX’s USE ‘SHADIN FADC’ **
If you are using both the FS-450 and the GNS420 in the unit litres, and the transmitted value in the GNS 420 shows wrong by the factor 0.37. For example:
FS-450 FOB equals 40 Liters but the Garmin 420 FOB equals 15 Liters. We believe the GNS 420 misinterprets the 40 transmitted as 1/10th of a Gallon and converts it into Litres E.g. 40 x 0.1 GAL * 3.7 [Litres per GAL] = 15 Litres.
Your FS-450 will have to come into the factory for software upgrade. Contact JPI Tech Support at 800-345-4574 to arrange for upgrade.
This can happen when there is no ground speed being output from the GPS.
1. Go to pilot program mode (Hold both buttons to see PROGRAM).
2.Tap STEP and see GPS-C = 0 … 8. (Older instruments only have options 0 – 6)
3. Tap or hold LF to change the number to one of the following:
4. Tap STEP repeatedly to END Y.
Connect their pin# 6 on the Northstar M3P to RS422 (pin may be called RS-422A or SDA – *also RS-485 OK) to JPI EDM pin 2(rx) on the fuel flow connector or the FS-450’s pin# 9(rx).
Northstar pin SDB pin 11 should be left open.
**No programming of the EDM or FS-450 necessary because when these sense Northstar or NMEA-183 navigation data input, there will be no fuel data output.
If you get REM, RES or MPG messages during scan, it is working.
Select Aviation Format or Moving Map format from GPS.
For the EDM-700/800/760:
• Arnav pin 5(tx) to EDM pin 2.(rx)
• Arnav pin 4(rx) to EDM pin 1.(tx)
For the FS-450:
• Arnav pin 5(tx) to FS pin 9.(rx)
• Arnav pin 4(rx) to FS pin 6 (tx)
JPI EDMs use Pin#1 for RS-232 output (to GPS) and Pin#2 RS-232 input (from GPS)
GPS Comm Format Setting:
• Set FS-450 OR EDM-700 GPS-C=2. Set GPS receiver to “Format B.”
• Alternate: set FS-450 OR EDM-700 GPS-C=3. Set receiver to “Format A.”
• Alternate: set FS-450 OR EDM-700 GPS-C=4. Set receiver to “Format C.”
