3. Hardware Guide continued

The XF Evaluation Board has an on-board regulator which can accept 5VDC to power the on-board circuitry and

the XF modem. This product has two main power supply connection options and an optional direct modem power

supply:

• Main supply -- center positive barrel connector (J2)

• Main supply – terminal posts (TP1, TP2)

• Direct modem power supply – terminal posts (TP3, TP4)

Figure 2: Power Supply Details

The two main power supply options are internally connected and simply offer alternative connection methods. The

evaluation board is equipped with protection circuit to prevent reverse voltage as well as help with protection from

transients.

The Voltage input range is 4.75V - 5.25V.

Direct modem Power Supply allows to powering the XF modem directly without any onboard voltage regulation.

Remove the SB1 solder bridge to use this feature.

Don’t Hot Plug Vin.

UART Level Translation Interface

XF products require a reference voltage for interfacing the UART I/O lines. A reference voltage applied to pin 14

VCCIO SELECT (VREF) will set the interface voltage level for these signals. This allows for connecting these signals

directly to a user’s host system at its I/O voltage operating level. See the product User Guide for information on

which pins are translated.

The user can choose the translation level between 1.8V – 5.5V by connecting a voltage to selecting P14 VCCIO

SELECT. The VCCIO translation voltage is also applied to the RS232 translators.

Note: User must supply a VCCIO voltage to allow the interface circuit to work for Telit based modems. This interface must be supported even if the

UART port is not used as an AT command port. The handshaking lines (CTS, DTR) are used to provide operational signaling and functional control

such as low power modes.

UART Port

The XF Evaluation Board exposes the XF modem UART signals as thru-hole pads. The XF modems typically

support input signals TXD, RTS and DTR, and output signals RXD and CTS. These signals are translated to

operate at the level set by the VCCIO voltage applied to TP5-TP6 terminals. See the UART Level Translation

Interface section.

While the UART port can be directly connected to a host system, an alternative method would be to use a USB

to TTL serial cable such as the an FTDI TTL-232R-5V-WE or TTL-232R-3V3-WE. These cables can be directly

soldered to the XF Evaluation Board and can supply the VCCIO voltage to the VL pin as well.

USB Ports

The XF Evaluation Board allows access to virtual COM ports and modem ports via the USB on those products

that support it. A Type B USB cable must be connected between the XF Evaluation Board and a PC USB host. To

use this interface during the development you may need USB drivers. You can obtain USB driver information on

our website (www.janus-rc.com)

A XF Plug-in Modems may instantiate up to 6 COM ports when connected to a host. These ports serve various

functions depending on the product, and some products allow re-conﬁguring of the USB port functions. See the

applicable XF product User Guide for more information.

For proper power sequencing, the XF Plug-in Modem must be turned on before connecting the USB cable.

Voltage applied to the USB_VBUS pin before the unit is on may keep the it from turning on correctly.

Jumper Connector

The J1 jumper on the XF Evaluation Board can be used to ground the ON_OFF pin of Telit based cellular modems.

This will cause the unit to power on automatically when power is applied.

Using the J1 jumper precludes the ability to shut down the modem using the ON_OFF pushbutton, requiring

that the modem be shut down using a software command. Turning off a cellular modem without ﬁrst

unregistering from the network is not a recommended operating procedure.

RESET Button

The XF Evaluation Board has one RESET switch.

SW2 RESET is used to recover the operation of the XF Plug-In Modem’s terminal in case of unexpected error

resulting from the inability of the application to communicate with the terminal.

4. Getting Started

This will take you through the initial steps required that will allow AT commands to be sent to a Telit based cellular XF

Plug-In Modem. Some of the following components typically provided with XF Evaluation Kits will be required:

XF Evaluation Board 1

XF Plug-In Modem 1

Wall transformer, 5V 1

Type-B USB cable 1

Cellular Antenna(s) 1 or 2

GPS Antenna Optional

U.FL to SMA Cable 1 to 3

• Insert the SIM card if the XF Plug-in Modem has a SIM holder.

Turning ON the XF Evaluation Board

• Insert the SIM card if the XF Plug-in Modem has a SIM holder.

• A SIM card will be required for connecting to a cellular network with most cellular modems. Even without a SIM card,

any operational features of the cellular modem will still be available.

• Before connecting power to the XF Evaluation Board, plug a XF Plug-in modem into the sockets on the board. Connect

the XF Plug-in Modem into the Evaluation Kit Sockets.

• Make sure the alignment of the XF modem is correct, before placing it into the sockets.

• Connect a cellular antenna cable to the XF Plug-in Modem (label CELL) and connect a cellular antenna to the other end

of the antenna cable (SMA Connector).

• Connect power to the evaluation board. To use barrel connection, connect the 5V wall transformer power plug to the

power jack (J2) on the XF Evaluation Board. Otherwise use an external supply to connect the 5V to TP1 and GND to TP2

on the XF Evaluation Board.

• Connect power to the VCCIO terminal TP5 (1.8 to 5.5V).

• Press and Hold the ON/OFF Switch (SW1) push-button for 5 seconds to enable the XF Plug-in Modem1.

• After releasing the SW1, the XF Plug-in modem may take several seconds to initialize before it is able to accept AT

commands. Yellow LED will be turned on during this stage if the default #GPIO settings are in effect.

NOTES:

1. The ON/OFF Switch is used for Telit based modems; for other products (e.g. WiFi) refer to the speciﬁc XF product User Guide.

2. On Telit based cellular modems you can have the XF Plug-in Modem turn-on automatically when power is applied by shorting the AUTO ON jumper

J1. With this method, the modem can’t be turned off using ON/OFF switch. Refer to the AT command guide for how to turn off modem using the

#SHDN command.

USB Communications

• Follow the steps mention in the Turning On the XF Evaluation Board section to turn on the board.

• Connect the USB cable to the evaluation Kit and to you PC.

• If you are using Windows Operating System, you can go to Device Manger and check the MODEM and COM ports that

are instantiated. Depending on the speciﬁc modem, at least one COM port will support AT commands. MODEM ports

also support AT commands; look at the port properties to determine the proper /COM port number to use.

• You should now be able to send ‘AT’ commands to the modem. To conﬁrm a proper connection, send the command

“AT” followed by a line terminator (Enter key) on the terminal and you should see “OK” as the response.
