7.2.2.1. Serial Port 1 - Serial communication signals (RxA_1 and TxA_1)
The FOX3-2G/3G/4G devices incorporate a full duplex serial channel in the accessory port which allows two devices to
communicate directly via RS232 serial ports. All supported baud rate are controlled by PFAL commands. In order to
communicate with the FOX3-2G/3G/4G devices, it is recommended to use the FOX3-2G/3G/4G PromotionKit since
you will find there all what you need for your evaluation. The signals on these pins are obtained to RS232 compatible
signal levels.
RxA_1 Receive channel and can be used for executing commands and firmware update.
TxA_1 Output channel for responses and system data to any software (e.g.
HyperTerminal, Workbench).
7.3. Inserting a SIM card into the SIM holder
FOX3-2G/3G/4G devices have a GSM modem that requires a SIM card to access to the mobile network services. The
SIM card is obtained from your mobile provider and must be activated for GSM data services before using it. Together
with the SIM card, you receive a 4-digit PIN number. Entering of the PIN allows your device to access the mobile
network.
To insert the SIM card into the FOX3-2G/3G/4G' SIM holder, follow the steps below:
1) Remove the power supply and any other connections from the device. Turn the FOX3-2G/3G/4G devices on
their back side as shown in the figure 14 below.
2) Indicate the SIM card holder on the left of the battery try (1). To open it, push the metal slider in direction
marked “OPEN ”.
3) Flip the card holder up (2).
4) Insert the SIM card (3) into the card holder in direction as shown in the figure below.
5) Flip the card-holder back (without force) (4), then hold it pressed and move the metal slider in direction
marked "LOCK" until it stops.
6) Insert the SIM card cover in the direction as shown in picture below (5) and slide it until it stops.
7) If you have already ordered a backup battery to connect it to the FOX3-2G/3G/4G (e.g. B1 - 1000 mAh battery,
see figure 14.1 below), just plug in the 3pin connector of the battery cable to the battery connector on the left
side in the battery tray (FOX3-2G/3G/4G PCB).
8) Finally, place the battery cover and then screw it with both screws and a T6-TORX screwdriver (6). When
tightening the screws, apply a tightening torque equal or less to these values: TORX 6 screwdriver with a fixed
torque of 0.3 - 0.4 Nm
