Power Supply

The Evaluation Board requires 5VDC to power the evaluation PCB and module. The evaluation board has two power supply connection options: center positive barrel connector or terminal block direct wire connection.

The Evaluation Board is equipped with protection circuitry to prevent reverse voltage, as well as help with protection from transients. The board can withstand a reverse voltage of -40V and a peak voltage of 60V. The circuitry is set to clip any input greater than 5.6V to a safe level.

Any input above 5.6V will read for a set period, and if before 2.0 uS has not returned to safe level, the over-voltage protection will activate and turn off the output.

To re-enable the output, power must be cycled or the SWITCHER_EN pin (DIP pos. 7) must be pulled low at least 3.0 μS and then released. Alternatively, if the power returns to a safe level for 36.0 mS the output will re-enable.

Power supply requirement:

Voltage: 5Vdc ± 5% Power: 10W peak

Serial Interfaces

RS-232 Serial Ports

The Evaluation board for the Plug-In terminals has two RS-232 serial ports.

AT COMMAND PORT:

This port is available to send AT commands to the terminal. Please refer to the CF Plug-In User Guide for serial port details for the speciﬁc terminal you are evaluating.

Typical Port Settings:

Baud: 115200 Data bits: 8 Parity: None Stop Bits: 1 Hardware Handshaking: CTS/RTS

Trace Port:

This port is used by the HSPA910CF terminal as a secondary serial AT interface. This port is not used for Python script upload. However, during development of Python scripts this port can be used to receive debug ‘print’ statements. In order to do this, AT#PORTCFG=3 should be used. Hardware handshaking is not available on this port.

Port Settings:

Baud: 115200

Data bits: 8

Parity: None

Stop Bits: 1

Hardware Handshaking: N/A

Serial Interfaces continued…

UART Translator Interface:

If the user wants to communicate with the modem’s serial interface via the on board UART translation, you can attach to the SIP header interface, P18. The full UART is broken out, along with TRACE TX and TRACE RX.

The translator’s modem side level is referenced to VAUX, meaning it is OFF when the modem is off. This function will tri-state the signals as recommended in the Plug in Modem User Manual.

The user can select between their own input voltage level and 3.3VDC by adjusting the J8 jumper setting.

1-2: 3.3V

2-3: User VCC In

If User VCC In is used, the header position #1, labeled UART VCC IN, should be connected to the desired power supply.

Interfaces continued

Serial Interfaces continued…

USB Serial Ports:

The development board allows access to virtual COM ports and modem ports via the USB. To use this interface during development you will need to download the USB drivers from the Janus website (www. janus-rc.com).

The HSPA910CF will show several virtual COM ports after the drivers are installed. These are USB0 through USB6, along with a modem for applications like Dial Up with Windows. This allows for applications like simultaneous AT commands, voice calls, and Python tracing.

These ports can be conﬁgured in various ways depending on the user’s application, but by default USB0 and USB3 are AT command ready after enumeration.

Typical Port Settings:

Baud: 115200 Data bits: 8 Parity: None Stop Bits: 1 Hardware Handshaking: N/A

You will want to reference the HSPA910CF Ports Arrangements application note for full details on using the AT#PORTCFG command.

Please note that in order for proper power on sequencing, the modem must be turned on ﬁrst. The USB VCC line must be disconnected until the device is on otherwise it may not power up correctly, or properly install the USB drivers. The development board already handles this power sequencing for you in both automatic turn on and manual turn on modes, but it is good to note for your implementation outside of the development kit.

Audio

The development board is equipped to take advantage of the DVI signals present on the HSPA910CF and EVDO910CF. The connection available to the user is in separate 3.5mm EAR and MIC ports. The audio uses the MAX9867 IC and is set for capacitorless differential mode. Control of the MAX IC is done via the I2C available on the modems (using GPIO 9 and GPIO 10) with the AT#I2CWR command.

Terminus 910CF Modules Evaluation Kit User Guide Page 5 Rev: A00 Date: 07/31/13

Push Button Switches

The development board has 2 push buttons to control the state of the Plug in Modem.

Cell ON/OFF

This switch is used to toggle the modem ON or OFF. When the board is set to manual control, this signal must be used to turn the modem ON by holding the switch for 5 seconds and then releasing.

Cell RESET

This switch is used to recover operation of the Plug in Terminal in case of unexpected error resulting from the inability of the application to communicate with the terminal.

LED Indicators

The board is equipped with an LED stack with Red, Yellow, and Green LEDs.

Green – Connected to the modem’s GPIO #2, adjusted with the AT#GPIO command

Green LED Status Device Status

Permanently Off GPIO is LOW Permanently On GPIO is HIGH

Yellow – Connected to the modem’s GPIO #1, which doubles as the cell status indication.

Yellow LED Status Device Status

Permanently Off Cellular radio is off Permanently On On/Searching Slow Blinking (0.3 sec on / 2.7 sec off) Registered Fast Blinking (0.5 sec on / 0.5 sec off) Shutting down

Red – This LED is an indicator to show the status of VBUS, which indicates if the USB connection is active.

Red LED Status Device Status

Permanently Off VBUS is LOW Permanently On VBUS is HIGH

RF Interfaces

There are two brackets for the RF connections to the antenna. The board itself does not have an RF interface; instead it allows the user to run mini coax cables to hard points for antenna access.

CELLULAR –

This bracket is for an SMA ended cable, in our evaluation kit we include a Murata GSC to SMA connector for this purpose.

GPS –

This bracket is for an MCX ended cable, in our evaluation kit we include a Murata GSC to MCX connector for this purpose.

Development Board Jumpers and Headers

There are several jumpers available on the board to allow maximum ﬂexibility.

J1 Power Selection:

1-2: Power Jack/Terminals

2-3: USB VCC

This jumper controls what the board itself will be powered from, allowing the user to do power analysis of the Plug in Modem by itself in regard to the main power input.

If the USB conﬁguration is used, please note that only the evaluation board and a majority of its components will be powered by the USB. The attached CF module and evaluation board protection circuitry will not be and will still need to draw its power from the main “Power In” screw terminals or barrel jack. The protection circuitry will add a draw of roughly 1.0mA.

J2 Modem VBUS Enable

1-2: Enabled

Open: Disabled

This jumper controls if the VBUS signal can be attached to the Plug in Modem. This ONLY controls the VBUS signal to the Plug in Modem; this jumper has no effect on powering the development board from the USB connection.

J8 UART Voltage Level

1-2: 3.3V

2-3: User VCC In

This jumper controls what voltage reference is used for the on board UART translation. The user can select between a speciﬁc desired input voltage level and 3.3VDC.

If User VCC In is used, the header position #1, labeled UART VCC IN, should be connected to the desired power supply.

J3 ON/OFF CONTROL

1-2: Automatic

Open: Manual

This jumper controls if the board will automatically turn on the Plug in Modem. The on board microcontroller will handle the power sequencing regardless of the selection; this simply allows the user to utilize the CELL ON/OFF switch to turn the unit on or off.

P15, P16, P17 COMS Header Rows

1-2: Translator

2-3: RS232

This header section is for choosing which section of the board to communicate to the modem through.

Audio

The audio connection can be utilized by any of the Plug in Modules that have a DVI interface. This section assumes that AT communication to the modem has been achieved.

HSPA910CF

• Enable the DVI interface and set it to master mode AT#DVI=1,2,1

• Set the interface type, and sample information. AT#DVIEXT=1,0,0,1,0

• Set the handset microphone gain. AT#HSMICG=2

• Disable the handset sidetone. AT#SHSSD=0

• Write the MAX9867 register information. AT#I2CWR=9,10,30,4,19 Wait for response ”>” then enter the register information >00109000100A330000330C0C09092424400060 Press CTRL+z to send the information Wait for response “OK” AT#I2CWR=9,10,30,17,1 Wait for response ”>” then enter the register information >8A Press CTRL+z to send the information Wait for response “OK”

• Test the audio output by using a test tone generation. AT#TONE=5,10 This will send out the DTMF tone for the #5 key press, for 1 second.

If the tone can be heard, the audio path has been set up and can now be utilized for voice calls or other purposes.

If the audio cannot be heard or is very quiet, the TSVOL command can be utilized to bring up the volume.

Example AT#TSVOL=255,1,10

This adjusts all audio types, and a max value of 14 can be used. Please see the AT Command Reference for full command details.
