RF Keyboard Encoder

6 Function Description

6.1 Encoder Buffer

The eKK6511 will buffer 24 bytes first-in-first-out order when the system is able to

receive scan codes from the keyboard. The eKK6511 generate RF data frame

according to FIFO and keyboard status. Then, modulation the data frame into serial

signal to RF Tx module. When key pressed, the EKK6511 will generate a make code

into FIFO. If key not released, eKK6511 will generate a make code into FIFO every

200ms. When key released, the eKK6511 will generate a break code into FIFO.

6.2 Device ID

The eKK6511 has support two device ID mode:

Controllable ID mode: Using the 3 bits DIP switch to control the device ID.

Random generate ID mode: Using the push bottom to generates a random device ID

(255 sets) and restores in EEPROM (93LC46). The eKK6511 will broadcast 10

seconds the new device ID after push bottom released. When battery exchange or

reset, the device ID will recovery from EEPROM.
