The shell’s material is ABS. LCD screen is made of imported high hardness acrylic, and the hardness is equal to the tempered glass.

1.1   Double-Holder

 

          

The size of convert ring: 22.2mm, 25.4mm, 28.6mm are optional.

1.2   Single-Holder

              

 

2.1 Working Voltage: DC24V 36V 48V (set by the meter), other voltage could be customized.

2.2 Mode of Connection:

Standard Connectors Line Sequence:

1: Red Line (VCC): Power Line

2: Blue Line (K): Controller’s power Line

3: Black Line (GND): Ground Line

4: Green Line (RX): Receiving communication

 

 

5: Yellow Line (TX): Sending communication

Extended Functions:

Headlight: White Line (GND): Headlight Negative

Brown Line (DD): Headlight Positive

PWM Assistance grades control, Independent external speed sensor. Line colors should be defined separately.

 

3.1   LCD Display

Speed indicator, PAS grades indicator, Battery indicator, Error indicator, Single Trip Distance and Total Distance, Headlight indicator, Single Driving Time indicator.

3.2   Parameters Setting

Power on/off, Headlight on/off, 6KM/H Cruise control, Wheel size setting, Max speed setting, Auto stand-by and sleep mode setting, Background luminance setting, Working voltage setting.

3.3   Communication Protocol: UART

 

 

P01  Background luminance. 1 is the darkest, 3 is the brightest

P02  Unit of the mileage. 0 is KM, 1 is MILE

P03  Voltage grades. 24V, 36V, 48V. The original voltage is 36V.

P04  Sleep time. 0 is without sleep, other numbers stand for the sleep time (1-60 min).

P05  PAS grades.

     0, 3 grades mode: 1 grade 2V, 2 grade 3V, 3 grade 4V

     1, 5 grades mode: 1 grade 2V, 2 grade 2.5V, 3 grade 3V, 4 grade 3.5V, 5 grade 4V

P06  Wheel size (inch) Precision: 0.1

P07  Speed measuring magnet. Range: 1-100

P08  Speed limit. Range: 0-100km/h, 100 means without limit

     No-Communication Status (controlled by the meter): when the real speed is over the ones we set, PWM output would be shut off; when less than the speed we set, PWM output would be turned on automatically, the driving speed would be ±1km/h; (Speed limit is for PAS, not for Throttle)

     Communication Status (controlled by the controller): The driving speed keeps same with the ones we set. Random error: ±1km/h. (Speed limit is for both PAS and Throttle)

Notes: These data are based on KM. When changing KM to Mile, the speed value on the screen would convert to correct Miles automatically, but if you do not change the setting of speed limit from KM to Mile, it would be different from the real speed limit in Mile.

P09  Zero start & Non-zero Start. 0 is Zero Start, 1 is Non-zero Start

P10  Driving mode.

0         is driven by PAS. Throttle is useless at this time.

1   is driven by Throttle. PAS is useless at this time.

2   is driven by PAS & Throttle. Throttle is useless at Zero Start status.

P11  PAS sensitivity. Range: 1-24

P12  PAS start strength. Range: 0-5

P13  PAS magnet type. There are 3 types: 5, 8, and 12.

P14  The Current-limiting of Controller. The original Current is 12A. Range:1-20A

P15  Controller’s under voltage setting.

 

P16  Reset ODO. Long press  for 5s, ODO could be reset.

 

5.1   During riding, need change PAS/Speed grades, shortly press    

5.2   During riding, need change data in Multi-function Area, shortly press ;

Long press , could switch status between MODE and ON/OFF;

Long press as a compound button, is mainly used for parameter setting, which could reduce misoperation due to complicated operation.

(No compound button with short-time press, because it’s difficult to operate.)
