Table: Output Signal Specifications
¹ Mode identifier: A = autonomous, E = computed (accurate trajectory calculation),
M = manual input, S = simulation mode and V = data not valid (including idle mode).
²
Talker ID change to “TI” ($TIROT…) from “HE” is available when connected to a Rate of Turn indicator.
³ Frequency of heading output signal IEC61162-1 can be set by Dipswitch S2.
Frequency of heading output signal IEC61162-2 is 50Hz.
Jumper J7 till J10 can be used to Selection between IEC61162-1 or IEC61162-2.
