RV-M7 Data Radio Modem Technical Manual

Installation

1. Secure the M7 modem using the four mounting holes on the side flanges of the unit. 
2. Connect a DC power source to the DC IN connection on the front of the modem.  Use the supplied cable, and connect the RED wire to +, and the black wire to – (ground).   The black wire and the case of the M7 should be connected to earth ground.
3. Connect a good quality antenna, tuned to the operating frequency, to the RF connector on the front of the modem.  Use a good antenna, and place is at as high-above obstructions as possible. 
4. A separation distance of at least 20 centimeters must be maintained between the transmitter's radiating structures and the body of the user or nearby persons.
5. Connect the computer, terminal, controller, or other hardware device that will be using the M7 modem to its DB-9 serial I/O connector using a shielded cable. Secure it to the M7 with the two mounting screws on the sides of the DB-9 connector.
6. If the antenna is mounted out doors, us a lighting arrestor in-line with the antenna, and properly ground the antenna and the M7 chassis to an earth ground.
