First start

After unpacking, the modem is ready to use. The modem can be connected to the target system using one of the following interfaces.

  • USB
  • RS485
  • RS232

Only one interface can be used at a time. The modem requires power supply, and even with a USB connection, a power supply is necessary. It is not powered from the USB port.

Power supply

The device can be powered by connecting a power source to the terminal block:  

  1. Loosen or remove the screws on the terminal block.
  2. Connect a 8–36 VDC power line to the terminal block.
  3. Tighten the connections, using the screws on the terminal block.
  4. Turn on the power source.

Note that the device does not have an on/off switch. It automatically turns on when it receives power. It takes a couple of seconds for the system to boot up. Once the system is ready, the RED LED will light up.
