P=5, Output5.

F=0, to close the output (open drain);

F=1, to open the output (low voltage).

Example: W000000,020,1,1

15.2 Output Control (Conditional)

Command: W******,120,ABCDE or W******,220,ABCDE

Description: Send this command to control the Output of VT310. This command is only workable when the speed is below

10km/h(command 120) or 20km/h(command 220) and GPS is available.

Note:

ABCDE represents Out1, Out2, Out3, Out4, and Out5 respectively.

If A or B or C or D or E,

=0, to close the output (open drain);

=1, to open the output (low voltage);

=2, to remain previous status.

Example:

W000000,120,10000

W000000,220,10000

15.3 Application Examples for Outputs

15.3.1 Engine Cut

Relay Connection: Connect a relay as below picture shows:

Calculate the correct VCC value according to relay’s parameter to comply with the following requirements:

Output open drain sink voltage (ineffective) 45V max

Output Low voltage sink current (effective) 500mA max
