GO device installation for rail service vehicles
Learn where to mount the GO device and which details to record before installation.
Recording vehicle and device information
Record the following information before proceeding with installation. This information is needed during the installation check:
-
Serial number of the GO device, shown below
-
Vehicle fleet number or license plate
-
Vehicle year, make, model, and VIN
-
Odometer and engine hours, if available
Finding a suitable mounting location
Locate an unexposed, dry place to mount the GO device. This is typically under the dash.
Mount the device to a solid part of the vehicle, either on the chassis (frame) or another solid surface that does not move or vibrate excessively during normal vehicle use.
Keep the GPS antenna facing skyward. For GO7 and all subsequent devices, the GPS antenna is at the bottom of the device.
Telemetry interfacing and wiring for IOX-AUXM (optional)
Review how to wire the IOX-AUXM and check its inputs when adding rail vehicle sensors.
Install and interface the GO device with telemetry sensors as required.
Plug the IOX-AUXM into the GO device or the IOX chain before powering the GO device. This ensures that the IOX is recognized.
For about 30 minutes after the GO device is first powered on, when all three LEDs flash and six swift beeps sound, the device enters debug mode and attached IOX-AUXMs enter input learning mode.
For consistent learning results, keep all telemetry inactive or off before powering the GO device. Start the vehicle engine. Once all three LEDs are on, cycle through all applicable telemetry for 15 seconds. For example, turn on PTO for 15 seconds and then turn it off, or lower the hi-rail for 15 seconds and then raise it.
In learning mode, the GO device beeps X times for each change in state, where X is the AUX number. For example, if the hi-rail is wired to AUX2, the device beeps twice when the hi-rail is lowered or raised. Use this to verify that the connections work correctly.
One IOX-AUXM supports up to four auxiliary inputs. If additional inputs are required, see Expanding the IOX-AUXM.
Record which telemetry sensors are connected. This information is needed during the installation check.

Expanding the IOX-AUXM
Review how two IOX-AUXMs report up to eight inputs and how the loop sets the AUX range.
Each IOX-AUXM reports four auxiliary inputs. Daisy-chain two IOX-AUXMs to report up to eight inputs. By default, an IOX-AUXM reports AUX 1 through 4.
Before connecting the IOX to the chain, cut the red and black loop covered in heat shrink, known as the short, on the IOX-AUXM that must report AUX 5 through 8.
Cutting the loop makes the IOX-AUXM always report AUX 5 through 8, regardless of whether AUX 1 through 4 is already installed.
Daisy-chain the two IOX-AUXMs.
Termination shunt
Review which shunt to keep in place when IOXs are linked in a chain.
The IOX-AUXM comes with a termination shunt installed in its expansion port.
Remove the termination shunt from each IOX in the chain except the last one. Keep the last shunt installed and secure it with a cable tie.
Hi-rail wiring
Review the magnetic sensors and wire connections used to track hi-rail status.
Hi-rail vehicles use magnetic sensors or proximity sensors to report hi-rail status to the GO device. For proximity sensor mounting and wiring, see Installing a Harsco hi-rail proximity sensor.
The following instructions apply to magnetic sensors. Both magnetic sensor models have a contact assembly (magnetic switch) and a mounting bracket (magnet).
Connect the red sensor wire to the orange (AUX2) input on the IOX-AUXM cable.
Hi-rail wiring schematics
Review the wires, gap, and ground points for both types of hi-rail magnetic sensor.
Sensor model 03-01-0005, manufactured by George Risk Industries, part number 4402-A:
Sensor model 03-69-0116:
There must be a negative signal (ground equivalent) when the hi-rail is down and no connection (open circuit) when the hi-rail is up or locked.
When the hi-rail is up and the vehicle is on the road, the sensor and magnet should be within 0.5 to 1.5 inches of each other.
When the hi-rail is down and the vehicle is on rails, the sensor and magnet move away from each other. The sensor sends a ground signal on the red sensor wire connected to the orange (AUX2) input on the IOX-AUXM cable.
For both sensor models, run the second wire inside the cab. Connect the white wire on model 03-01-0005, or the black wire on model 03-69-0116, to a reliable vehicle ground point near the red sensor wire connection to the orange (AUX2) input.
Grounding the wires to the outside vehicle frame is not recommended. This helps avoid corrosion or damage from debris or extreme weather conditions.
Installing a Harsco hi-rail proximity sensor
Learn how to mount, wire, and test the sensor supplied for a Harsco hi-rail system.
These instructions apply to hi-rail solutions manufactured by Harsco Industries, for projects where Harsco supplies the proximity sensor and 5 m cable.
-
Use a feeler gauge to set a 5 mm (3/16-inch) gap between the end of the sensor and the hi-rail cam.
The red lines in the photo mark the gap.
-
Run the harness into the under-dash area near the vehicle's OBD connector, where the GO device will be installed.
Cover the exterior harness run with split wire loom or braided sleeving to protect it from flying debris. Secure it with cable ties every 15 to 30 cm (6 to 12 inches) in locations where it will not become pinched or damaged.
The schematic below applies to ifm efector inc. sensor IGM206-00 with a 5 m cable.
Color code: BN = Brown; BK = Black; BU = Blue.
Inverting an AUX2 input for a hi-rail installation
Learn how to use MyGeotab to invert the AUX2 signal for the Harsco sensor.
After connecting the proximity sensor, invert the AUX2 signal in MyGeotab. This procedure applies to Harsco Industries hi-rail solutions for projects where Harsco supplies the proximity sensor and 5 m cable.

Power take-off wiring
Review the PTO connection to AUX1 and the required signal states.
The power take-off (PTO) connects to the AUX1 wire on the IOX cable.
-
When PTO is engaged, there must be a negative or positive signal.
-
When PTO is disengaged, the signal must be the opposite of the engaged signal, or float.
The mechanical gearbox is mounted on the transmission. In most cases, a PTO switch or relay circuit inside the cab can be used instead.
