11.2 When【Speed Source】is set to【Motor Wire】or【Hall Sensor】, the distance is the accumulation of the
product of speed and time per 0.1 second.
11.3 When【Speed Source】is set to【VESC】, remote and receiver will read VESC’s ABS data by UART port
and calculate it to distance and display.
12. Main battery voltage display:
12.1 This function works in both Esk8 and Esurf modes.
12.2 When【Speed Source】is set to【VESC】, it will obtain VESC voltage information by UART port;
Otherwise, voltage information is obtained by BAT port on receiver PCB.
12.3 Please make sure receiver GND and your main battery GND are connected(common ground).
12.4 If receiver is not connected to main battery or VESC UART port, remote will not display anything about
main battery.
12.5 If receiver gets voltage information, remote will show voltage in bars according to preset 【Batt. Type】
and 【Batt. Ser Num】.
Under the voltage bar on remote screen, it’s marked 【xx Batt.】. “xx” means current 【Batt. Ser Num】value,
please check if it’s same as your battery specification.
If 【Batt. Type】or 【Batt. Ser Num】is set different from your battery’s actual value, voltage display will be
incorrect. Please make sure correct settings of both.
If voltage bars only have 2 or less left, the bars and 【xx Batt. 】words on screen will flash to remind you
charge your battery.
13. Voltage, Current, Temperature display:
13.1 When【Speed Source】is set to【VESC】, Remote and receiver will obtain voltage/current/temperature
information by VESC UART port. The function automatically takes effect after correct connection and settings
with VESC. You can press the Function Button to turn over the main interface data to view these data. Please
refer to “Item 5.2” in this manual.
13.2 It works for both Esk8 and Esurf modes when use with VESC.
13.3 VESC has temperature sensitive resistor on PCB. It can measure VESC’s temperature. But motor
temperature display needs:
13.3.1 Motor has built-in 10K NTC thermistor and it’s connected to the Temperature pin of hall sensor
connector.
13.3.2 In VESC_TOO, Beta Value for Motor Thermistor is set to 3950K.
14. Relay and Transistor switches using instructions:
14.1 Both switches work in Esk8 and Esurf modes.
14.2 When relay switch is in original position(no display of【1】in Screen Main interface) , COM(common point)
and CLO(normally close) are connected.
14.3 When relay switch is moved (display of 【1】in Screen Main interface) , COM(common point) and
OPE(normally open) are connected.
14.4 Max current of relay switch contacts is 3A. Recommend use this switch for water pump or main lighting
system.
14.5 When Transistor switch is turned on, the load circuit will be connected to the GND terminal. Max current
2A. Recommend to use it for indicator LED.
14.6 When transistor switch is on (display of【2】in Screen Main interface), transistor switch source will be
connected to GND and turn on LED. When it’s off(no display of【2】in Screen Main interface), LED is off.
14.7 Recommend 5-12V voltage for the transistor switch. Voltage over 20V will burn the transistor.
14.8 Transistor switch pin SWI is closed to BAT pin and MOT pin. Please make sure no electrical contact
between them. Or it will burn transistor.
