2.3 RESET

2.3.1 General presentation

This signal is used to force a reset procedure by providing low level during at

least 500 µs.

This signal has to be considered as an emergency reset only. A reset procedure

is automatically driven by an internal hardware during the power-up sequence.

This signal can also be used to provide a reset to an external device. It then

behaves as an output. If no external reset is necessary this input can be left

open, if used (emergency reset), it has to be driven by an open collector or an

open drain output:

•

RESET pin 14 = 0, for Modem Reset,

•

RESET pin 14 = 1, for normal mode.

3.4 Environmental characteristics

To ensure the proper operation of the Fastrack Modem, the operating

environment must be within a specific temperature as described in the table

below.

Table 9:

Ranges of temperature

Operating temperature range -20 °C to +55 °C

Storage temperature range -25 °C to +70°C

3.5 Protections

The modem is protected by a fuse directly bonded on the power supply cable.

The model of fuse used is: F 2.5 A L 250 V.

The modem is also protected against voltage over +32 V.

When input voltages exceed +32 V, the supply voltage is disconnected in order

to protect the internal electronic components from an overvoltage.

Filtering guarantees:



EMI/RFI protection in input and output,



Signal smoothing.
