SERIAL COMMUNICATION INTERFACES
This section describes the electrical characteristics of the serial interfaces in
the R4 Navigation System, as well as the supported IEC 61162 input and
output sentences.
7.1
Electrical Characteristics R4 Display
7.1.1
Output Drive Capacity
Each talker output can have a maximum of 10 listeners drawing 2.0 mA.
7.1.2
Input Load
Each listener draws less than 2 mA @ 2 V input voltage.
7.1.3
Termination
If needed, 1 k
Ω
line termination resistors can be placed in the terminal block
on the input ports.
7.1.4
Schematics
Each of the RS422 serial interfaces on the R4 Display fulfils the
requirements as specified in Ref. [2]. In addition, they support baud rates up
to 115200. For details of input and output schematics, see Figure 7-1 and
Figure 7-2 respectively.
