15 m
Supply module Ex i BT - Bluetooth
Wiring:
Blue wire
necessary (example connection to AC)
Green line
necessary
The signals RTS and CTS are not in use/no function internally. The terminals can only be used to connect the
wires.
For data lines (green and orange) we strongly recommend to use shielded (e.g. CAT5, similar or higher
quality) cables.
Note:
The interfaces of the power supply module Ex i BT are passive.
The power supply module supplies only the hand scanner with power, but not the interface. The
interface works in Ex i version with 5V
DC
.
The interfaces themselves are supplied with power via the Ex-HMI or other Ex-device.
