| Pin | Name | Description | - | 1 | Ear (-) | Ear Phone - Note: This is an output only that is connected directly to the modem. Input voltages should not be applied. | 2 | Ear(+) | Ear Phone + Note: This is an output only that is connected directly to the modem. Input voltages should not be applied. | 3 1-Wire 1-Wire® Interface
Note: Maximum voltage on this pin is 3.3 VDC 4 ADC In #2 Analog-to-Digital Input, 0 – 32 VDC 5 ADC In #1 Analog-to-Digital Input, 0 – 16 VDC 6 Ground System Ground 7 Ground System Ground; Connector has longer pin for MFBL. 8 Digital Digital Input #2 (GPI9) Input #2 9 Digital Digital Input #1 (GPI1) Input #1 10 RS-232 CTS RS-232 CTS Out Note: This is an output only. Input voltages should not be applied. 11 Ignition Vehicle Ignition Sense Sense 12 MIC (-) Microphone - Note: Although this signal is AC (capacitively) coupled to the modem, there is
a 1K Ohm resistor to ground with a power rating of 0.0625 W. This limits max-
imum input voltage to <7.9VDC. Designed for audio only, any other signals or
voltages may damage the device.
13 MIC (+) Microphone + Note: Although this signal is AC (capacitively) coupled to the modem, the MIC-
BIAS output from the modem has a 330 Ohm to 1K Ohm voltage divider with
a 10 uF, 6.3 V capacitor connected between the two resistors and to ground.
Assuming a 2.6 V MICBIAS output, this limits the maximum voltage that may
be applied to the MIC+ input to approximately <15 VDC so that the voltage rat-
ing of the capacitor is not exceeded.
