KEY MATRIX

Key No.1~6

Continuous key output with it pressed, and multiple keying is possible.

Key No.7~18

These keys are the single-shot keys and when input is made, signal is output only one time.

3. TRANSMISSION COMMAND

Transmission command is in one word 12-bits configuration. C1~C3 are code bits adaptable to many models,

H,S1 and S2 continous signal and single-shot signal codes ,and D1~D6 are Key input data codes in 6-bits.

DATA

Single-shot

As the multiple keying is possible , key No .1~6 are capable of output 63 commands through a combination of

D1~D6data.

Key No . 7~18 are the single-shot keys for output 12 commands , and 75 commands can be output through a

combination of continuous key (multiple keying is possible ) and single-shot key .

5. CODE BITS(C1,C2,C3)

Code bit can be made at one terminal with diodes connected through T1 ~ T3 timing terminals .
