How to install the modem
8.4.1
Power supply
Use a high-quality power supply cable with low resistance. This en-
sures that the voltages at the connector pins are within the allowed
range, even during the maximum peak current.
When the unit is powered from a battery or a high current supply,
connect a fast 1.25A fuse in line with the positive supply. This protects
the power cabling and modem.
8.5
Securing the modem
Before securing the modem take into account the amount of additional
space required for the mating connectors and cables that will be used in the
application.
Where access is restricted, it may be easier to connect all the cables
to the modem prior to securing it in the application.
Securely attach the INSYS GPRS mini modem to the host application
using two 3mm diameter pan-head screws
