Revision 0 – 4 – Technical Guide

2.1.2 External Interface

The GD30 and GD50 telephones have two external connectors:

1. a multi-way connector for use with external accessories such as hands free kits and PC data card.

2. additional contacts for charging the battery pack while inserted in the desktop charger.

Main Unit <==> External I/O

No. Name H/H <=> EXT Total Function H/H Circuit

1 GND ==> 6 Ground

2 PA_ON ==> 1 Gating of spectrum analyser for Transmitter

performance testing

L: Off, Hi - Z: On)

3 nLOGIC_PWR ==> 1 Accessory Power Control signal.

In the handsfree this is logical OR’ed with

IGNITION in order that the software can

maintain the Handsfree power-on state if the

user is in a call and that the IGNITION is

switched off. L: Power-on, Hi-Z: Power-off

4 IGNITION <== 1 IGNITION is used in two cases.

1) Determine the mode of operation of the H/H

when the Handsfree accessory is attached.

L: At a suitable time enter dummy sleep mode

and therefore minimise the drain on the car

battery (nLOGIC_POWER = Hi - Z)

H: Normal mode

2) Satisfy 2nd of 2 conditions for sending

initialise Testset command and entering Testset

mode. (see nADP_SENSE for 1st condition)

L: Condition 2 satisfied

H: Enter Testset mode not satisfied

5 VBAT <=> 1 The pin is either an input or an output

depending upon the battery connection.

1) Battery/Dummy battery connected: Output

supply terminal for attached accessories.

2) No connection: Low current input supply

terminal for non-RF performance checking in

Testset Mode or Flash programming.

6 nH/F_SENSE <== 1 Handsfree sense line

L: connected

H (internal pull-up): disconnected

7 nRADIO_MUTE ==> 1 Radio Mute

L: mute, Hi-Z: unmute)

8 RX_AUDIO ==> 1 Accessory Receiving Audio

-16 dBm0 = 76.7m Vrms

9 GND ==> Ground Refer to pin 1

10 EXT-PWR <== 2 Power supply for battery charging, Power ON/

Off control and accessory control circuits.

11 NON_HOOK <== 1 Indicates if the optional second handset is on or

off hook. In handsfree operation, if the optional

handset is not fitted this signal defaults to on

hook. (Low.)

12 SERIAL_OUT ==> 1 Downlink Serial Data

(Baud rate is same as SERIAL_IN)

13 SERIAL_IN <== 1 Uplink Serial Data

The baud rate is dependant upon the attached

accessory, whether operating in Testset Mode

or Flash Downloading.

SMS cable: 9600 bps

RS232 Direct cable: 38.4 kbps

Data adapter: 33.8 kbps

Testset: 9600 bps

Flash Download: 56 kbps

14 nADP_SENSE <== 1 NADP_SENSE has 5 possible states. The state

is determined by the value of the pull-down

resistor in the attached accessory / test set.

NADP_SENSE has 2 purposes as follows:

1) To identify an attached accessory.

Open (H): No attached accessory

82 kΩ=± 1% (MH): Headset Adapter

56 kΩ=± 1% (M): SMS Cable

33 kΩ=± 1% (ML): RS232C Direct Cable

GND (L): Data Adapter

2) Determine whether the 1st of 2 conditions

are satisfied for sending the initialise Testset

command on SERIAL_OUT, and entering

Testset mode (see IGNITION for 2nd condition).

H/MH: Condition 1 satisfied

M/ML/L: Enter Testset Mode not satisfied

15 NH/F_ON ==> 1 Accessory Sending & Receiving Audio paths

L: unmute, Hi-Z: mute

16 GND ==> 6 Refer to pin 1 Refer to pin 1

17 TX_AUDIO <== 1 Accessory Sending Audio

-16 dBm0 = 40.4 m Vrms

18 GND ==> 6 Ground connection of Dual Charger Refer to pin 1

19 GND ==> 6 Ground connection of Dual Charger Refer to pin 1

20 GND ==> 6 Ground connection of Dual Charger Refer to pin 1

21 GND ==> 6 Ground connection of Dual Charger Refer to pin 1

22 CHARGE_ON <=> 1 The Dual Charger shall hold CHARGE_ON to

the middle level until a H/H is inserted into the

front slot.

H: 2.0<=V<=3.0 volts; Dual Charger detects

connection of H/H

M: 1.0<=V<2.0 volts; Unconnected

L: 0.0<=V<1.0 volts; Dual Charger detects

connection of H/H

23 EXT_PWR <== 2 The Dual Charger shall control switching of the

power supply to the front slot (corresponds to

EXT_PWR) based on the state of the

CHARGE_ON signal.

H: EXT_PWR supplied

L: When the H/H can determine whether or not

to set CHARGE_ON. After the insertion of the

H/H, EXT_PWR shall be subsequently supplied

withinTBA hours
