Before the Omni SW 2014 was released, Stromer used an LCD display on the handlebars for ride management. There are two display versions: the V1 and the V1.1.
Operating instructions
The multilingual operating instructions can be downloaded from the myStromer AG website. here can be downloaded.
PIN code
The factory-set locking code is 1234, but it can also be different (e.g. for used cars) as it can be changed individually (see operating instructions p. 10).
Pin assignment
The Dipsplay has two connection cables with plugs:
5-pin plug:
Pin 1 (Pink): Ground (Mass)
Pin 2 (Yellow): Texas (UART send data from controller to display)
Pin 3 (Blue): Power in (Battery voltage/Vbatt, approx. 36V–42V – used to supply the system)
Pin 4 (White): POW_OUT (Switched Plus – Signal returns from the display to power on the controller)
Pin 5 (Green): Prescription (UART received data from display to controller)
3-pin plug:
It is connected to the right brake lever and serves to tap into the so-called „brake sensor.“ The contact, designed as a normally closed switch, provides the signal for the recuperation mode.
Rot / Red: SIN (Signal In)
Weiss / White: Ground (Mass)
Processor / Communication / FW updates
- The display uses a Infinion XC886/888CLM 8-bit single chip microcontroller.
- Communication with the display is via UART Rx/Tx. Signal processing of the Hall sensors and the temperature sensor is done directly in the controller. The necessary information exchange with the display takes place via this interface.
- New firmware must be loaded manually via the UART connection.
Display codes
The basic settings (time, password, sensor sensitivity, etc.) on the display are not as user-friendly to adjust as on the Omni. They are accessed via so-called codes.
First of all: It is not possible to tune the maximum speed, whatever is set with the codes!
In the Code table you will find a list of all the codes I know.
