Description

Data Output

Data output of 3-wire bus.

A 100 kΩ resistor connected from this pin to VSS enables key locking.

If signal is not activated, a pull down resistor (100 kΩ) is inserted.

CS1

Chip Select 1

Chip select signal for external EEPROM.

If signal is not activated, a pull down resistor (100 kΩ) is inserted.

Basic Definitions

Keyboard Layout

Password is set to 0123 and is used to access basic

parameter settings (see Table 3: Parameter settings). The

set-up programming is normally done in the factory during

manufacturing of the telephone sets. The factory settings

can be loaded into the EEPROM (see Figure 3: Memory

allocation for external EEPROM).

V+

V-

R/P

PIN code is default set to 1111 and is used by the user to

protect certain user settings (see Table 5: User

programming with PIN code). The PIN code can be

changed by the user.

Default settings are shown in bold.

Figure 1: Keyboard Layout

Program procedures are entered with the [PG] key.

Pressing any invalid key or going on-hook during

Maximum R_ONfor key closure: 1 kΩ

programming will abort the program mode and no changes

will be stored. Ending a program procedure by pressing the

[PG] key will store the changes and exit the program mode.

Minimum R_OFFfor open key: 1 MΩ

See “Table 1: Key definitions” for description of key

functions
