INSTALLATION GUIDE
STATUTORY REQUIRMENTS
FCC: This device complies with Part 15.247 of the FCC Rules.
Operation is subject to the following two conditions:
- This device may not cause harmful interference.
- This device must accept any interference received, including interference that may cause undesired operation.
FCC: Unlicensed operation limits the radio power. High gain aerials may only be used to compensate for cable losses.
WARNING – EXPLOSION HAZARD
Do not disconnect the device while the circuit is live unless the area is known to be non-hazardous.
NOTE
The 925U-2 module ships from the factory as a bridged meshing radio.
All connections must be SELV <50 Vac and <60Vdc
If communication with the older legacy 915U-2’s is required, radio operating mode can be changed with a firmware downgrade, which is available on the USB Stick in the box. Please follow the “Downgrade procedure” document which is also on the USB.
Models
9250-2-869-869.5 το 969.9MHz – 869 MHz ISM band (Europe)
925U-2-900-902 to 928MHz-900Mhz FHSS band
Antenna installation
When selecting an antenna, consider radio proximity.
Use Figure 1 as a guide for installing an antenna and attaching it to the 925U-2-XXX.

The following illistrations show the port connections on the 925U-2-XXX.
Power Supply Wiring
The ground (GND) and “SUP-terminals are connected internally to the ground (Earth) terminal.
Connect the screw terminal on the end plate to ground (Earth) for surge protection.
Expansion I/O Power and RS485 serial connection
An on-board RS-485 terminating resistor provides line termination for long runs.
Only enable terminating resistor on the last device connected on the RS-485 cable.
