On-board computer (v0.82B)

The On-board computer is equipped with a large sunlight-resistant screen to display main parameters, driving modes settings, software updates for all system components, battery control, and the charging state of the devices via USB. On the left side of the On-board computer there is a slot for a microSD card, which is used to update the firmware, save screenshots, import and export configurations and settings of the On-board computer and Controller. On the back of the On-board computer there is a power button, which is configured in the menu Devices > Controller > Extra parameters > Disable button.

Technical specifications:

• LCD size 3.6“
• FSTN, monochrome
• Screen resolution 240×128 px
• Screen heating
• RGB-button backlight
• MicroSD slot
• USB-charger 5.2V 2А
• Password protection
• Multi-Language (English, Russian)
• IP54 class

In the kit:

• GoPro fork mount.
• USB charging wire.
• PHD 2.0 4P connector — 4 pcs.
• PHD 2.0 6P connector — 1 pcs.
• PHD 2.0 8P connector — 1 pcs.
• Pins for crimping — 26 pcs.
• If you don't have a crimping tool, you need to order “Crimped wires for the Display”.

You can look at the connection diagrams for other devices at this link. By default, all control devices (thumb throttle, brake levers, switches, etc.) are connected to the ports located on the back of the On-Board Computer. To access, you need to unscrew five screws and remove the plastic cover. For connection, PHD 2.0 connectors and crimp pins are used, which are included in the kit. If you do not have a crimping wire tool, for example, SN-2549, then you need to order “Crimped wires for Display”. The On-board computer is connected to the Controller with one CAN-wire 1.2 meters length, which is included in the Controller kit. Note, the CAN-wire from the Controller should be connected to the SYSTEM port on the On-Board Computer.

If you want to connect control devices directly to the Controller, you need to order “Controller-side inputs”, in the diagram at the link above this switching option is designated as “Alternative connection”. You can also use a mixed connection option, for example, connect the thumb throttle to the On-board computer, and the brake levers to the Controller.

The screenshot below is one of the Main screen configurations. The layout of the elements on the screen depends on the theme and settings. In this example, the Hurma theme is installed.

Navigation on the On-board computer screen is carried out by the four bottom buttons. By holding down the two central buttons, you can take a screenshot of the screen, the file will be saved in .bmp format on the microSD card (if it is inserted into the On-board computer). Functions of the On-board computer buttons, from left to right:

• Switch the menu screen, cancel, return to the previous menu
• Switch up, less
• Switch down, more
• Select, apply

The picture below shows the menu navigation diagram, the red arrow is the left button, the blue arrows are the two central buttons, the green arrow is the right button of the Onboard computer.

To go from the main screen to the statistics section, double-click the left button of the On-board computer. Then, with the second and third buttons, you can switch screens with statistics General statistics > User statistics > Trip statistics > From charge statistics.

There are four types of statistics available:
General statistics — statistics for all time of using the Controller and On-Board Computer.
User statistics — statistics for any time period you choose. You can reset the data when you need it.
Trip statistics — statistics since the Controller was turned on.
From charge statistics — statistics between battery charges.

The list of parameters that are displayed for each type of statistics are the same and are calculated based on the type of statistics, with the exception of the Charge Cycles in the General statistics, instead of this item, in all other types of statistics is displayed the Average speed indicator, which is calculated while driving.

Mileage — mileage in kilometers or miles (depending on settings).
Travel time — driving time, hours, minutes, seconds.
Max speed — maximum speed, km/h or mph (depending on settings).
Charge cycle — number of battery charging cycles (for General statistics only).
Average speed — average speed, km/h or mph (depending on settings).
Regen Wh — the amount of energy returned to the battery during regenerative braking, in watt-hours (Wh).
Used Wh — the amount of energy consumed, watt-hours (W*h).
Max power — maximum power, watts (W).
Wh/km (Wh/mi) — the amount of consumed watt-hours of the battery per kilometer (or per mile) of run, (Wh/km or Wh/mi).
Max phase current — maximum phase current, amperes (A).

Statistics reset:
General — go to the General statistics screen, press and hold the left button of the On-board computer, the system will ask for a password, enter the default password or your custom password. For more information on setting up a password, read the Password setup section. After entering the password, the statistics will be reset. If you do not enter the password, then you can return to the main menu only after restarting the On-board computer. You can do this either by deactivating or using the button on the back of the Trip Computer, provided that you have configured it in the section Devices > Controller > Extra parameters > Disable button.
User — go to the User statistics screen, press and hold the left button of the On-board computer, the statistics will be reset.

The options for selecting values are similar to the setting Hot key 1 type — Nothing, USB Charger, Security block, Turn off screen backlight, CAN_1-CAN_16.

In the menu item On-board computer > Button setup > Latch filter, you can configure a filter for more stable button operation. The choice of values from 0 to 10. This setting refers to the four buttons of the On-board computer Hotkey 1-Hotkey 4. Sometimes, especially if the functions are configured for all four buttons, interference may occur that will affect the stability of the buttons. In this case, you can increase the filter value. The button will turn on more slowly (it will need to be held longer), but more stable.

The Onboard computer > Button setup > Short press hot key menu item allows you to configure the activation of the function by short pressing the On-board computer buttons, without holding it for 2 seconds.

In the menu section On-board computer > Control setup, the parameters of the throttle and brake levers connected directly to the Onboard computer are configured.

Mileage total — controller's mileage in kilometers (km).

The On-board computer supports two ways to determine the speed:
— according to information from the Controller.
— by a speed sensor (reed switch), which is connected to the On-board computer.

If you select the Controller value, the controller readings will be used as the speed data source. This method is suitable for direct-drive or mid-drive motors without overrunning clutch. After selecting the value Controller, you must:

1. Specify the number of pole pairs for the magnets in the menu Controller > Motor setup > Pole pair. The number of pole pairs for different models of motors can be found in the Motor Information section. If your motor is not on the list, check with the manufacturer or use an Internet search.

2. Enable speed calculation (if disabled) in the Controller > Extra parameters > Speed calculation and specify the wheel circumference in millimeters in the Controller > Extra parameters > Circumference. You can use the online calculator to calculate the circumference.

If selecting a value Display the speed will be determined from an external sensor, which is used, for example, in a bicycle computer. The speed sensor must be connected according to the diagram to the SPEED connector on the rear panel of the On-board computer. After setting the Display value and connecting the speed sensor, you must specify the wheel circumference in millimeters in the On-board computer > Data source menu.

In the menu section On-board computer > Security you can set a password that will be requested when turning on the Controller. Without entering the password, the controller will not respond to controls.
