FCC ID:IHDT56FV1 General This document content describes the operation of the G24 Evaluation board (EVB) P1. The G24 EVB supports two G24 versions: OEM, and fixed mobile. For the fixed mobile a secondary board is mounted on EVB (Piggy Board, using connector P50). The follow PDF file contains EVB schematic and layout (all References are searchable) 8899_schem_place_s earch.pdf Exhibit 8 Page 2 of 8 Applicant: Motorola Inc.

G24EVB main power is divided to 2 roots, 1st to EVB, and 2nd to G24 unit. Exhibit 8 Page 4 of 8 Applicant: Motorola Inc. FCC ID:IHDT56FV1 Getting Started
- Select power supply source (Wall Adapter, lab power supply, or battery), and connect it to suitable jack (either line 1, 2, or 3).
- Set P203 jumper (line 9) according to your main power source selection.
- Make sure that P201, P200 jumpers are connected (line 24).
- Mount G24 on G24EVB using P1 connector (line 23).
- Connect G24 Antenna to P2 (line 10) - Optional
- Turn On main power switch S200 (line 4), led indicator D200 is On.
- Press S110 On/Off switch (line 11) for turning On G24 unit. Exhibit 8 Page 5 of 8 Applicant: Motorola Inc. FCC ID:IHDT56FV1 General Purpose Switches The G24 contains General Purpose Switches for simulating testing states. For detail schematics see PDF file in General Section (at the beginning of this doc). Line 12 EMU Bus UID pin S170, S171 and S160 1st switch are used to simulate UID pin of the G24 EMU bus. The default position (as shown in figure) is that UID pin is not connected.
- Switching On (left) S160 UID position shall enable S170, S171.
- Select Only one position from S170, S171 according to EMU spec. A/D operation G24 has 3 General A/D. G24 can simulate analog voltages vary from 0.1V-1.7V.
- Set S161 switch position to desired voltage level.
- Enable desired ADC (S160). Exhibit 8 Page 6 of 8 Applicant: Motorola Inc. FCC ID:IHDT56FV1 Line 14 GPIO Audio G24 has 8 General Purpose I/O. S120, S121 along with GPIO led indicators simulate GPIO state. G24 has internal pull-ups.
- Switch left position GPIO line is disconnected.
- Switch right position GPIO line is shorted to ground. S140 Audio position selects the Audio path of G24.
- Switch left position Analog Audio path (Using G24 internal vocoder).
- Switch right position digital Audio path (Using G24EVB on board vocoder). SPI Enable SPI logger (line 8) Exhibit 8 Page 7 of 8 Applicant: Motorola Inc. FCC ID:IHDT56FV1 Option connects between WKUPO_N & WKUPI_N (Pins 16 & 26) in G24 70 pin. Line 20 General Positions
- *, # - Simulating *, and # phone keys.
- WAKEUP - connects WKUPI_N (pin 16) to ground
- ADPTR connects Wall Adapter voltage to USB VBUS.
- CHRG connects between USB VBUS to G24 Ignition.
- DP-DN connect between G24 USB DP & USB DN signals IGN connect G24 Ignition to G24EVB voltage. G24 EVB Top View (With Keypad board) Exhibit 8 Page 8 of 8
