9. Installation
1.
Secure the
M7
modem using the 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, or 18AWG wire, 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 a GPS antenna to the SMA connector of the
M7 GX
.
Although a passive antenna may work if the cable length is very
short, it is recommended that an amplified antenna be used,
rated for 3.3V operation.
6.
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.
7.
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.
8.
Connect Digital Inputs. The stock
M7 GX
has up to 3 digital
inputs, using the input pins of the RS-232 serial port. An open
circuit or ground is a 0, and if they are connected to a positive
voltage greater than 3V, they are a digital 1.
