Digital inputs
The digital inputs are divided into three groups of four, which are
galvanically separated from each other and from the device. Each
group has its own GND terminal for the reference potential.
If the inputs are controlled via an external voltage, the common
reference potential is connected to the “GND” terminal and the signal
is connected to the respective input IN1 to 12.
3 ETH Ethernet interface for connection of a PC
The CP305 can be integrated into the Bender/hospital network via the
Ethernet interface. Parameters can be set on the PC, and data as well
as the history memory can be read out. Connected measuring devices
can be displayed with their channels.
4 R Terminating resistor of BMS bus
If two or more devices are connected to each other via the BMS
bus, the bus line must be terminated at both ends with a resistor
(R = 120 Ω) (can be switched on via dip switch on the underside of the
CP305).
