Pin 7 = RTS Input
Pin 8 = CTS Output
Pin 9 = RI Output
To connect to a PC as DTE, a pin-to-pin, 9-wire 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 3m.
2.5.8 SIM Interface Characteristics
The
Telit wireless modems
EZ10-GPRS, /-PCS (with PYG option)
support plug-in type
Subscriber Identity Modules (SIM) according to GSM11.14 Phase 2 – with 3 Volts supply ONLY.
For the technical characteristics of the SIM, refer to the documentation supplied together with the
SIM by the Mobile Network Operator or Service Provider.
The
Telit EZ10-PCS wireless modems (with PYG option)
have an enhanced SIM card reader
with a sensor that allows to detect a “hot” removal of the SIM, therefore the SIM can be extracted
and re-inserted while the module is still on.
NOTE
: On the
Telit EZ10-PCS wireless modems (with PYG option)
the sensing of a hot
removal of the SIM is not supported during power saving mode (AT+CFUN: 5).
2.5.9 Insertion and Removal of the SIM
The terminal has a
built-in toggle spring (Push-Push) SIM holder
, accessible through a slot in
the panel at the antenna side of the housing.
Do not insert or remove the SIM when the product is in power saving mode.
To insert and remove the SIM, a plastic strip of the same width of the SIM and appropriate length
of ca. 50-100 mm shall be prepared as a tool. The figure printed on the panel shows the position of
the cut edge and the direction, how the SIM shall be inserted.
Insert the SIM and push it with the tool slightly inside until the spring snaps in. Removing the tool,
the SIM shall remain inside the EZ10 Terminal. For removing the SIM, push the tool slightly inside
until the spring is released so that it pushes the SIM outside when the tool is retracted.
2.5.10 Antenna
Output
NOTE: BEFORE connecting the EZ10 Terminal to a Power Supply source, a suitable
Antenna shall be connected and properly installed.
As accessory, a magnetic surface mount antenna with 2.5dBi gain, ca. 2,5 m of coaxial cable and
SMA connector is available.
The antenna has to be installed with care in order to avoid any interference with other electronic
devices and has to guarantee a minimum distance from persons (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 minimum interference with other electronic systems, a
space of min. 40 cm around the radiating part should be free, at least of electrically conducting
materials (except the ground plane on which it is attached).
