Lamp Status

When then unit is On, the returned packet (27 byte long) is described in the following table:

1E BE EF 10 13 00 .. .. 01 01 00 01 01 15 01 00 01 10 00 00 00 UU UU .. SS LL LL

0 1 17 18 20 21 22 24 25 26

where bytes marked with .. are not relevant.

The response may be separated into 4 parts:

• 1 bytes (byte 0) that initiates the packet (1E)

• 17 bytes (bytes 1-17) that duplicate the sent command (apart from 2 of them — the CRC)

• 3 Error bytes (bytes 18-20) that signal errors in the processing of the command

• 6 Data bytes (bytes 21-26) that contain the requested data

If the 3 Error Bytes (bytes 18-20) are 00 00 00 then requested data are valid.

The tables below explain the meaning of returned data.

• Bytes 21 and 22 (labeled UU UU in the table above) contain Unit Working Hours.

UU UU is the hex representation of the number of working hours.

Therefore, if, for instance, UU UU = 09 D8 then Unit Working Hours is 2520.

• Byte 24 (labeled SS in the table above) contains the Lamp Status:

Oﬀ 00

Ignition 01

On 02

• Bytes 25 and 26 (labeled LL LL in the table above) contain Lamp Working Hours.

LL LL is the hex representation of the number of working hours.

Therefore, if, for instance, LL LL = 01 B6 then Unit Working Hours is 438.

If the unit is in Standby State the unit does not respond to this command.
