About iDEN Developer’s Kit
The iDEN Developer’s Kit for iO1500R OEM modem provides the capability of
transferring data and voice from an external equipment to the iDEN network using the
iO1500R (iO1000) module.
The kit includes an Evaluation Board that is designed to accommodate the OEM
module and other supporting components. A flex cable connected to the 30-pin ZIF
connector is used to connect the iO1500R module to the evaluation board. The OEM
modem RF connector provides the path to receive and transmit data from the iDEN
network.
The "iO1500R developers kit", FTN6363A includes the following accessories:
Evaluation board w/voice - FCN6412A
Data cable (RS-232) - FKN4369A
30 pin flat cable - 3086229J03
MMCX to Mini UHF jumper cable - 3002823C34
Antenna - RAF4136AMM
Mounting kit – FHN6525A
Board Set-Up
Unpack the mounting accessories.
Attach the 5 mounting rubber supports to the 4 corners and center points of the back
side of the board and put it on your desk (see board layout below).
Used the 4 screws and washers to screw an iO1500R (18) OEM modem to the board.
Verify that a SIM card (17) is inserted.
Connect the 30 pin flat cable (16) from the modem to the board.
Connect the RS-232 cable from the board (10) to your PC.
Connect the antenna jumper cable (19) from the modem to the external antenna.
Connect the audio accessories (if your application requires voice operation).
Set all switches to the proper position (see detail interface description below).
Connect DC power (3) and switch on the power to the board (1).

You can control and test the modem with the PC. Load the iX1500 applet to your PC
to get status and be able to analyze modem functionality. Download the developer
guide 9808901C42-A for instructions how to write an application for the iO1500R.

Detailed interfaces description
1. Main Power Switch – Switches the main power 3.8VDC to the board (S4 on
PCB).
2. Fuse 1A - protects external 12VDC power supply input (F1 on PCB).
3. External DC input connector – 12VDC or 3.6VDC can be connected (P1 on
PCB). Connect 12VDC to the right most pins (right pin 12VDC, central pin to
GND, as in the picture). Connect 3.6VDC to left most pins (3.6VDC to left pin
GND to central pin).

20. RS-232 status LED’s (D8-D11 on PCB)
21. Modem registration status LEDs (D2-D3 on PCB)
22. Audio volume for external speaker and headset DIP switch (S9 on PCB). For
maximum volume all switches have to be in the OFF position. Left most
switch (1) LSB. Right most switch (4) MSB.

Detailed Pin Descriptions of the evaluation board J1 ZIF connector
BAT_GND (Pins 1 through 5)
These pins are the ground return lines from the iO1500R and are connected together
with the same ground reference to the 3.6 V power supply for the iO1500R.
In-range indication-GREEN LED (Pin 6)
Blinking Green light - IN RANGE - the OEM is connected to the iDEN network.
Solid Green light – The iO1500R is in use.
Out-Of-Range indication, RED LED (Pin 7)
Solid Red light - OUT OF RANGE – iO1500R not connected to the iDEN network.
Blinking Red light – iO1500R is registering or connecting to the iDEN network.
BATT_VCC (Pins 8 through 12)
This is the 3.6 V iO1500R power supply.
MOD (Pin 13)
This pin is internally pulled down via 22K resistor. Mod pulled to 3V at power up sets
the modem to programming mode.
Ignition (OEM) On-Off (Pin 14)
Used to power up and power down the iO1500R OEM. This is the recommended
method for turning the iO1500R on and off. In an in vehicle applications it can be
controlled from the ignition line. When this pin is connected to ground, the OEM will
turn OFF. When this Pin is connected to BAT_VCC 3.6V, the OEM will turn ON.
OPTION_3V (Pin 15)
A regulated 3V output coming from the iO1500R with a maximum drive of 30 mA.
Voltage is available only when the OEM is ON.
MUX_CNTL (Pin 16)
This pin must be held at logic low (facilitated by internal 69K pull down resistor).
Opt_Select_1 and Opt_Select_2 (Pin 17, Pin 18)
The option select lines set the communication state of the module. To support RS232
communication, the option select lines must be connected at one of three modes:
“11” – Default mode via internal 22K pull up resistors.
“01” – Option select 1 is externally pulled to ground (only this option supports voice).
Audio Interface (Pins 19, 20 and 21)
These are input ground and output of the iO1500R audio communication.
RS232 Standard Interface 8-Wire Or 4-Wire (Pin 22 through Pin 30)
This is a 3V DCE RS-232 interface. For ±5V an external level shifter is used.
