2.16 Serial Communication Interfaces
2.16.1 Electrical Characteristics
2.16.1.1 Output Drive Capacity
Each talker output can have a maximum of 25 listeners drawing 2,0 mA.
2.16.1.2 Input Load
Input impedance for each listener input is 68 kΩ.
2.16.1.3 Termination
If needed, 1 kΩ line termination resistors can be placed in the terminal block on the
input ports.
2.16.1.4 Schematics
Each of the RS422 serial interfaces on the R4 Transponder fulfils the
requirements as specified in Ref[5] and Ref[6]. For details of the
schematics, see Figure 16.
