Issue

The SendPro device is unable to communicate when connected to a SendPro Cellular CDSP.

Cause

  • The SendPro Cellular CDSP is not receiving a cellular signal.
  • The SendPro Cellular CDSP is not communicating with the SendPro device.

Resolution

Check the LED lights on the SendPro Cellular CDSP.

  • If there are no LEDs lit, see Solution 1.
  • If the green and orange LEDs at the end of the device are on but the one by the network cable is not, see Solution 2.
  • If the orange LED is not on or is flashing, see Solution 3.

Solution 1: Check power

  1. Plug the power adapter into a functioning wall outlet and the SendPro Cellular CDSP.
  2. Try a different outlet.
  3. Contact Pitney Bowes if the wall outlet is functioning and the device LED will not light up.

Solution 2: Re-establish connection between the SendPro device and SendPro Cellular CDSP

  1. Turn off the SendPro device.
  2. Unplug power from the SendPro Cellular CDSP.
  3. Turn on the SendPro device and wait for it to fully start up.
  4. Check the SendPro Cellular CDSP and the SendPro device has a network cable fitted.
  5. Plug in the SendPro Cellular CDSP. The green LED should light up right away.
  6. Wait for the orange light to turn solid. This could take 3 - 5 minutes. Communication should restore once the orange light turns solid.

Solution 3: Improve reception by moving the SendPro Cellular CDSP

  1. Ensure the SendPro Cellular CDSP is at least 3 feet away from any electric appliance that could cause interference. Microwaves, digital copiers, and Wi-Fi routers are all examples of such appliances.
  2. Move the SendPro Cellular CDSP closer to a window or outside wall. Use a longer network cable. It should meet CAT5 or higher standards. Such standards are not provided by Pitney Bowes.
