The E9T control unit is provided of on-
board 220Ω
termination line resistor for RS-485 Bus.
When JP11 jumper (red highlighted) is :
Open : Termination line resistor disconnected
Closed: Termination line resistor connected
Suggested RS-485 cable
Manufacturer
: Belden
Application
: Industrial
Product code
: 3106A
Poles
: Twisted pair + single pole
Shielded
: YES
Type
: UV resistant
The Ground Terminal
E9T control unit have a GND (ground) terminal in order to provide a stable voltage reference for RS-485 shielded
cable. If a shielded cable is used for RS-485 connection it must be connected only in one side.
Do not connect the GND terminal to an external device ground !
Modbus communication settings
E9T control unit is provided of a dedicated menu accessible by the local user interface useful to configure the
