This guide is intended to help you get your RoadLog Electronic Logging Device (ELD) installed, up and running quickly and easily.
To avoid damage to the vehicle or risk of electric shock, always confirm the location of electric wires and air lines by consulting the vehicle’s owner’s manual or your local vehicle repair facility. If there is any uncertainty about the location of electric wires, disconnect the vehicle battery before starting.
Be careful when installing cable or wires to avoid kinks, knots or twisting in the line.
Be certain cable/wires are not rubbing on sharp edges.
Pen or pencil
Make sure you have the correct installation kit for your vehicle! RoadLog can be connected with 6-pin, 9-pin, 16-pin OBDII or open-end “basic” cable. Only one cable is required. Choose the one that fits your connector or choose the open-end if you have no connector and will connect individual wires to the vehicle. (For basic cable, installation by a professional shop is recommended. When using the basic cable the ignition line should be connected.) Each cable is supplied with the basic installation bracket. Y-Cables are an optional upgrade that retain an open cable connector in the cab.
Choose your mounting option. The “basic” bracket is included with each installation kit.
Suggestions For Bracket Mounting
BASIC BRACKET (included)
Choose your mounting location. IMPORTANT: Choose a location that will allow easy operation, but will not block your view of the road. The unit must be placed a minimum of 10 inches (20 cm) away from the driver.
A. Top of the dash driver’s left side*
D. Overhead console driver’s left side
B. Top of the dash driver’s center*
E. Overhead console driver’s center side
C. Instrument panel driver’s right side
F. Overhead console driver‘s right side
Attach your bracket. The bracket can be attached with the adhesive foam pads. When using the adhesive foam pads be sure to clean the surface with a single direction swipe by using an alcohol prep pad supplied in an installation kit. Let it dry and apply the tape with red peel side down towards the dash. The tape will cure in 24-48 hours. The best results are achieved when the surface is warm so you may want to warm up the cab if the ambient temperature is low.
Prepare the RoadLog. Unpack the ELD. Remove the service panel on the underside. Insert the Battery. Connect the cable. Close the service panel.
Recommended Cable Connect Direction
Harness leaves ELD perpendicularly to display as curves (1) and (2) shown in RoadLog ELD TOP VIEW. Routing harness under the rectangular cross-hatched area depicted at rear of this ELD illustration, and shown as curve (3), is not recommended as it can affect mobile performance.
Harness should leave ELD without curving, up to marking ‘A’ (few inches apart from device), as depicted in RoadLog ELD SIDE VIEW. Routing (4) should be avoided.
Connect cable to vehicle data port. Run the cable from the RoadLog to the vehicle data port. The cable can be run behind the interior dash panels via gaps between them or by their removal where necessary. Secure the cable out of the driver’s range of motion and moving parts – coil up and secure the excess cable by using zip ties provided. Connect the cable to the vehicle data port. The device will power up and be ready for the initial on screen setup.
If using the Open End Cable, follow the wiring indications shown below.
Install RoadLog into mount. Basic bracket: Place the RoadLog into the basic bracket and install the knobs. Adjust the screen view angle and then tighten the knobs.
Load paper roll. To load the paper roll (Part #3290-90010100), lift the access panel at the top of the RoadLog, lay the paper roll into the cavity and pull the leading edge of the paper forward, towards the screen. The roll should be inserted so that when the paper comes out, it curls towards the back of the unit.
Compliance sticker. Applying the included sticker to your cab is optional, but doing so will ensure anyone who sees it knows your vehicle is complying with ELD regulations.
Instructions for Open End "Basic" Cable
If using the Open End “Basic” Cable, follow the pin / wire color assignments from the table below:
The basic cable has a total of 8 wires and only Pins 1, 2 and 4 are connected: ignition, battery ( + ) and ground ( – ), respectively. The rest of the wires have to be connected according to the table below depending on the type of the vehicle.

RS232 data reception line
RS232 data reception (data input) line (for data communication with third party devices)
RS232 request to send output
RoadLog (DTE) requests the external equipment (DCE) to prepare to resolve data. When used for RS232 hardware flow control, RoadLog uses this line to indicate when it is able to receive RS232 data.
RS232 clear to send input
The external equipment (DCE) indicates if it is ready to accept data from RoadLog (DTE). When used for hardware flow control, RoadLog monitors this line in order to see when the external equipment is able to receive RS232 data.
