What Is Binary Playback?/Use
and Applications
and Applications
By inputting binary (Base 2) signals to Port Nos. 1 through 8
to select a phrase and inputting a start message to the START
terminal, you can then play back the selected phrase. A
maximum of 250 phrases can be selected and played back
with this method.

This allows you to specify 250 phrases with control signals
(from a switch or other ON/OFF signal device), without
having to use computers or other complicated equipment.

* To conduct Binary Playback, you will need to obtain a control
device capable of generating binary signals.
* Input of binary specifications should be completed in no more
than 50 milliseconds.

Connectors Used in Binary Playback
“1–8”: Phrases are specified in binary format using
combinations of 0 (Off) and 1 (On).
combinations of 0 (Off) and 1 (On).
“9 (START) “: Start phrase playback.
“10 (STOP) “: Stop phrase playback.
In addition to the connectors just described, shorting the 11/
12 (GND) (Ground) connectors enables “On.”
12 (GND) (Ground) connectors enables “On.”

Even without connecting to all eight connectors used for
making the binary specifications, you can still conduct
Binary Playback. The number of phrases that can be specified
is determined by the formula “two to the nth power minus
one” (with “n” being the number of connectors used).

Binary Playback. The number of phrases that can be specified
is determined by the formula “two to the nth power minus
one” (with “n” being the number of connectors used).
Example:
Using three timers or other such devices capable of
outputting the necessary signals gives two to the third power
minus one (i.e., 8 - 1 = 7), meaning you can specify the seven
phrases 001 through 007.
