2.4 Interface Description
2.4.1 Overview
BG864-2.4 provides the following interface connectors:
•
RS232 serial interface
Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 9 of 75
•
Mini-USB interface
•
ON/OFF Switch Slide
Furthermore, there are four led indicators (ARM, Bluetooth, Battery Charger and SR status) and one
push button (RESET).
Figure 4 – Interface overview
2.4.2 Supply Voltage
The BG864-2.4 can be supplied by an internal rechargeable Li-Ion battery or directly by the MINI-USB
port.
Power supply input is described in the following subsection and must fulfil the following requirements:
Li-Ion Batt. Supply Voltage Range 3.4÷4.2V
Mini USB Supply Voltage Range 4.5÷5.5V
Table 1 – Supply Voltage
Danger – Operating voltage range must never be exceeded; care must be taken
in order to fulfill Min/Max voltage requirements.
2.4.3 Battery source
Power is supplied by an internal rechargeable Li-Ion battery.
Battery voltage range is 3.4 ÷ 4.2V.
If the Gateway is connected via the Mini-USB to an external PC (or power supply) then the battery will
be automatically recharged by means of integrated battery charger circuitry.
Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 10 of 75
The battery capacity should be sized on the customer’s application and battery life requirements.
Warning – Do not charge the Li-Ion battery out of temperature range of
0
÷45°C.
Battery connector must be Molex 87439-0200 or compatible.
2.4.4 Switching the BG864-2.4 ON and OFF
The switch on/off slide button is used to turn ON or OFF the gateway
2.4.4.1 Switching ON Procedure
The BG864-2.4 switches on when slide switch is moved on the left.
.
BG864-2.4 operating system is operational after about 20 seconds from the power-on.
2.4.4.2 Switching OFF
The BG864-2.4 switches off when slide switch is moved on the right.
The BG864-2.4 can be switched off either by disconnecting the power supply from the MINI-USB port
and the battery or by software command.
It is suitable a software switch-off command before disconnect the power supply.
Note- When the slide switch is in OFF position and the battery is
connected, battery charge continues to function if BG864-2.4 is connect to
an external supply from the MINI-USB port

2.4.6 Serial Port
The RS232 standard interface serves to connect a PC, Data Terminal Equipment (DTE) or an
application, wich acts as host controller for the BG864-2.4 with all its functions.
Serial port connects directly the host controller with the UART-Debug of the ARM chip inside BG864-
2.4.
RS232 level translator is present on board.

3.4 Interface Description
3.4.1 Power connector
The power connector on the left side of the terminal is a Molex 2-pins connector (part no.: 43045-
0210).
Pin description:
•
GND = Ground reference
•
Input Power = 5 - 15 VDC
3.4.2 Supply Voltage
The external power supply must be connected to power supply input as described in the following
subsection and must fulfil the following requirements:
12 volts
5 volts
15 volts
Table 5 – Supply Voltage
Danger – Operating voltage range must never be exceeded; care must be taken
in order to fulfill Min/Max voltage requirements.
3.4.3 Battery source
The external power supply could be sourced by an external no rechargeable battery.
Battery voltage range is 5 – 15V.
The battery capacity should be dimensioned on the customer’s application and battery life
requirements.
3.4.4 Switching the GG864-2.4 ON and OFF
3.4.4.1 Switching ON
The GG864-2.4 switches on automatically each time the power supply is connected the first time or reconnected.

GSM ANTENNA REQUIREMENTS
Gain
Note- When the power supply cable is disconnected, it is recommended to
wait approximately 5 seconds before applying the power again.
3.4.4.2 Switching OFF
The GG864-2.4 can be switched off either by disconnecting the power supply or by software
command.
It is suitable a software switch-off command before disconnect the power supply cable.
Warning – Please note that hardware power off should be done only after
a proper GSM logoff. Any GSM device is request to issue a “detach”
request at turning off.
3.4.5 Antenna
3.4.5.1 Antenna Output
Warning – BEFORE connecting the GG864-2.4 to a power supply source, suitable
antennas shall be connected and properly installed.
The antenna has to be installed with care to avoid any interference with other electronic devices
and has to guarantee a minimum distance from the body (20 cm). in case this requirement cannot
be satisfied, the system integrator has to assess the final product against the SAR regulation.
For a good efficiency of the antenna and a minimum interference with other electronic systems, a
space of min. 40 cm around the radiating part should be left free of electrically conducting materials.
The less distance and the fewer obstacles between the SWS-GW antenna and the antenna of the
GSM/GPRS network base station, the less power is radiated by the gateway and the better signal
quality is achieved.
3.4.5.2 Antenna Connectors
The GG864-2.4 includes two SMA bulkhead female, class 4 (2W) co-axial connectors for the two
external antennas.
3.4.5.3 GSM Antenna Requirements
The GSM antenna for GG864-2.4 device shall fulfill the following requirements

3.4.6 Serial Port
The RS232 standard interface serves to connect a PC, Data Terminal Equipment (DTE) or an
application, witch acts as host controller of the SWS-GW with all its functions.
Serial port connects directly the host controller with the UART-Debug of the ARM chip of SWS-GW.
RS232 level translator is present on board.
3.4.6.1 RS232 standard interface connector
The connector mounted in the SWS-GW is a standard RS232 Sub-D 9pin female with these
characteristics:
Baud rate from 300 to 115.200 bit/s
Autobauding (300 to 38.400 bit/s)

Table 8 – serial port pin-out
To connect to a host controller, a pin-to-pin 9pin cable with D9 type connectors on both sides is
needed (1 male & 1 female). Shielding of this cable is recommended and its length shall not exceed
3 m.
