Getting started / Installation

This chapter gives you advice and helpful hints on how to integrate the HT63-E Terminal into

your application from a hardware perspective. Please read the information given in "Safety and

Product Care", page 10 and then read the information in this section before starting your

integration work.

There are several conditions which need to be taken into consideration when designing your

application as they might affect the modem and its function. They are:

The modem must be installed so that the environmental conditions stated in the Technical Data

chapter, such as temperature, humidity and vibration are satisfied. Additionally, the electrical

specifications in the Technical Data section must not be exceeded.

The modem has to be placed in a way that ensures sufficient GSM signal strength. To improve

signal strength, the antenna can be moved to another position. Signal strength may depend on

how close the modem is to a radio base station. You must ensure that the location, at which

you intend to use the modem, is within the network coverage area. Degradation in signal

strength can be the result of a disturbance from another source, for example an electronic

device in the immediate vicinity. More information about possible communication disturbances

can be found in section 5.3.5.

When an application is completed, you can verify signal strength by issuing the AT command

AT+CSQ. See "AT + CSQ Signal Strength".

Tip! Before installing the modem, use an ordinary mobile telephone to check a possible

location for it. In determining the location for the modem and antenna, you should consider

signal strength as well as cable length

The integrator is responsible for the final integrated system. Incorrectly designed or installed,

external components may cause radiation limits to be exceeded. For instance, improperly made

connections or improperly installed antennas can disturb the network and lead to malfunctions

in the modem or equipment.
