NoWire CellConnect™ GSM Modem Installation Notes
These instructions show you how to connect up the CellConnect GSM Modem to the NoWire equipment as well
as configure it for use in your system.
Note: NoWire COM2 can only have the GSM Modem mode operating or Modbus Slave RTU mode operating,
Not both at the same time.
Safety and Static Protection:
During this procedure remove power from NoWire and the GSM modem. The NoWire circuit board has
statically sensitive components. Though the circuitry is robust avoid static electrical charges whenever possible.
When handling NoWire, whenever possible, hold the circuit board by the edges to avoid touching the
components. Perform this procedure in a low static environment…not on carpet, not wearing nylon clothing, etc.
Discharge any static charges on your body by touching the grounded center screw on a standard electrical
outlet. If possible wear an anti-static wrist strap.
Installation Instructions:
1. Remove the blue cover then remove the 4 mounting screws on the corners of the NoWire circuit board.
Remove the NoWire circuit board from the case.
2. Remove the access plug from the bottom of the NoWire case. Locate the NoWire-GSM serial cable and
carefully push the connector through the plug being careful not pulling out the wires from the connector. Go
slowly and wiggle it attempting to minimize stress on the wires.
