LoJack ID data
This data is only available and
valid
, if:
•
Display Control Unit with actual software Rev
≥
3.20 (see Power-On procedure, page 8)
•
Direction Finder of variant [L] Law Enforcement
•
Configuration of Extended serial = ON (see Setup Page, point (10) )
•
Direction Finder is working with active LoJack >ID Filter<
•
Header (byte 0 of data) = 0x93 or 0x94
Valid LoJack ID decoding data is always marked by the first data byte (
header = 0x93 or 0x94
).
Byte No.
[0]
Header = 0x93 LoJack ID editing sub-page is selected / Filter = VLU,
all valid and received LoJack pulses are indicated
= 0x94 Lojack Decode & Bearing Mode with active Filter = ID

Number of bytes in the complete data stream
- decimal 26 = default value

Remark:
Only if byte no. [3], bit [0] gets “1” (Receiving On), then an active LoJack pulse is received and so on the
corresponding LoJack ID valid, otherwise the LoJack ID only shows the actual adjusted LoJack Filter ID of the
direction finder.
