4 General about SattBus installation
A shielded twisted pair cable with a minimum
of 3 twists/m and 80–120 Ωcharacteristic
impedance should be used as the bus cable.
Minimum area is 0.35 mm 2.
Note! The same type of cable must be used for
the entire SattBus installation.
Cable length and number of nodes
The total length must not exceed 500 m.
Termination
The bus cable should be terminated with
100 Ωresistors, connected at the two most
remote ends, measured along the cable. See
figure above.
All units in EPC 50 system, i.e. OP, I/O and
MT 50, have internal termination resistors
which can be connected/disconnected by
jumpers.
For EPC 50 I/O-board termination resistor is
connected by placing jumper XJ3 in position
TERM.
