4.2. SIM interface
4.2.1.
SIM IC
This optional chip located on the development kit can emulate a SIM card. It has the
following specification.
3GPP TS 51.011, 51.014, 43.019, 23.040, 23.140
3GPP TS 23.048
3GPP TS 22.048
ETSI TS 102 221, 102 222
ISO / IEC 7816
The SIM IC is compatible with the ISO 7816-3 IC standard required by the GSM 11.11
Phase 2+ standard.
The SIM IC interface insures the power on (SIMVCC) of the SIM Chip and the
communication with it through a data signal (SIMDAT), a clock signal (SIMCLK) and a reset
signal (SIMRST).
Switch S601 to position "2" to use this SIM.
4.2.2.
SIM CARD
The SIM Card interface is compatible with the ISO 7816-3 IC card standard required by the
GSM 11.11 Phase 2+ standard. The module also supports Release 99 of the SIM Toolkit
recommendation and supports a Fixed Dialling Number directory.
The SIM Card interface insures the detection (SIMCD), the power on (SIMVCC) of the SIM
Card and the communication with it through a data signal (SIMDAT), a clock signal (SIMCLK)
and a reset signal (SIMRST).
Switch S601 to position "1" to use this SIM card.
The jumper TB704 connects the SIM card presence detection to the GPIO2 (IO2)

UART 1
A V24 interface is provided on external pins of the module with the following signals:
RTS/CTS
RX/TX
DSR
DTR
DCD
RI
The signals levels are adapted and connected to the male Sub-D9 connector “UART 1” on
P202. It supports speeds up to 115.2 KBPS and may be used in auto bauding mode.
Eight LEDs are provided on Development Kit to show the status of the UART 1 signal. The

The signals levels are adapted and connected to the male Sub-D9 connector “UART 2”.
Four LEDs are provided on Development Kit to show the status of the UART 2 signal.
This UART is only available for the software debug, signals from SPI bus are converted into
RS232 signals and their voltage adapted.
The 2 jumpers TB404 and TB405 must be set. The UART 2 interface is therefore enabled on
the Sub-D 9 connector.
In case of malfunction, push S401 for around one second to reset the SPI/RS232 converter
chip.

4.4. GPIOs interface
GPIOs interface is provided on external pins of the module with the 8 signals.
S701 Is used to set up GPIOs as input or output. When the switch is closed, the GPIO is
configured as input. When the switch is opened, the GPIO is configured as output.
S702 allow to drive the input. When the switch is closed, the GPIO level is at low level. When
the switch is opened, the GPIO level is at high level.
5 GPIOs are available and named IO1 to IO5
3 other signals named IO6 to IO8 are reserved for SAGEM use.

4.5. Analog audio interface
The HILO can manage an external microphone (MIC) in single mode and external speaker
(32 ohms HSET_N/HSET_P) in differential mode.
Thus, one receiver and one microphone can be connected to the module with the following
characteristics (see SAGEM references in the document “URD1 5635.1 007 70230 - Hilo
application note”):
Receiver 32 ohms up to 120 ohms
The microphone can be supplied using the internal HILO bias supply (recommended but
not mandatory) or any other external bias system compliant with selected microphone
within the HILO inputs limits.

GSM Antenna
The two antennas connectors can be connected to the HILO module either via a mini coaxial
connector or via 2 spring contacts.
When the spring contact E101 and E102 are chosen, simply plug the Hilo module and
connect an antenna to P102.
When the mini coaxial cable is used : connect the cable to P104 on one side and to the
Hilo module coaxial antenna out on the other side. Then connect an antenna to P103.
In this configuration, if the Hilo development kit is used to make some accurate radio
performances measurements, please add a tape on the E101 and E102 to avoid to
create a "stub" effect resulting in radio performance losses.

Auto power-on
The HILO can power on automatically on the development board when a jumper is set on
TB301 between position 4 and 3, low level active PWON is therefore set to ground level.
4.9.6.
Hardware reset.
The Hilo module can control an external reset device via the GPIO3 (IO3).
Connect the jumper TB102 to enable the connection between the chip and the GPIO.
It can also be done manually by using S100 to provoke a hardware reset.
In both cases, a jumper must be set in TB301 between position 4 and 3. This pull-down
PWON signal and then enable an auto power-on whenever the power supply is available.
