Detailed Pins Descriptions
RS232 Standard Interface 8-Wire Or 4-Wire (Pin 1 through Pin 9)
This is a 3V DCE RS-232 interface. For ±9V use, OPTION_3V (Pin16) can supply
power to an external level shifter IC like MAX3238E. The 9-volt external level shifter
output can be connected to a PC COM port.
Audio Interface (Pins 10, 11 and 12)
These are future options of the iO1500R to provide audio communication.
Opt_Select_1 and Opt_Select_2 (Pin 13, Pin 14)
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.
Diode – Anode to Pin 13 and cathode to Pin 14.
MUX_CNTL (Pin 15)
To use RS232, this pin must be held at logic low (facilitated by internal 69K pull
down resistor).
OPTION_3V (Pin 16)
A regulated 3V output from the iO1500R with a maximum drive of 30 mA. This can
be used to drive an external RS232 transceiver IC.
Voltage is active only
when the OEM is ON.
OEM On-Off (Pin 17)
Used to power up and power down the iO1500R OEM. This is the recommended
method for turning the iO1500R on and off and in vehicle applications it can be used
as an ignition sense to power up. 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.
MOD (Pin 18)
This pin is internally pulled down via 22K resistor. Motorola recommends routing the
MOD signal to an external connector. Should iO1500R software need to be updated,
this pin must be available externally, or the flash cannot be programmed, and the
iO1500R module will have to be removed from the product to reprogram it. Mod
pulled to 3V at power up sets programming mode.
BATT_VCC (Pins 19 through 23)
This is the 3.6 V iO1500R power supply. All should be driven by the same
source. Power: 3.6V ±5 % max., ripple 50mV. Input current: Avg. 1A, peak 2.5A.
Out-Of-Range indication, RED LED (Pin 24)
This OUTPUT is the Out Of Range Connection Status. It is a switched 3V output
voltage with a maximum drive of 10 mA.
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.
