Connectors Used in Terminal Rec
1–8: Phrases are specified in binary format using
combinations of 0 (Off) and 1 (On).
9, 10: Combinations of 0 (Off) and 1 (On) are used to specify
record, erase, and playback.
15–18 (CONT OUT): Outputs signals for confirming the
presence or absence of phrases.
In addition to the connectors just described, shorting Ports 11
and 12 (Ground) enables “On.”

Operational Specifications for
Terminal Rec
Phrases are specified by combinations of signals of 0 (Off)
and 1 (On) to the Port Nos. 1 through 8 as well as Port Nos.
11 and 12, and record, playback, and erase functions are
specified with combinations of control signals of 0 (Off) and
1 (On) to Port Nos. 9 and 10.
Presence or Absence of Phrases
If there is a binary-specified phrase that has already been
recorded, a signal is output from the CONT OUT connector
(Port No. 15). If there is an empty phrase, no signal is output.
* During Terminal Rec, the CONT OUT connector functions as
a connector for signals confirming the presence or absence of
phrases. Note that this differs from the normal function of
CONT OUT.

9: 0 (Off)
10: 1 (On)
→ While control signals are being input, the specified phrase
is recorded. When input of the control signal stops,
recording then ends.

* Recording does not start if there is a binary-specified phrase
that has already been recorded (the recording instruction is
disabled). When recording, either specify an empty phrase or
delete the existing phrase before recording the new one.
Additionally, in Terminal Rec, since a make signal is output
from the CONT OUT connector when a specified phrase has
already been recorded, this allows confirmation using a
connected external control device.
* When headphones are being used, no Busy Out signal is
output.
* When you're using the Terminal Recording Mode, recording
takes place immediately, without entering trigger recording
standby.
