UNIVERGE SV8100/SV8300
Terminal
Number
T1 When warning tone is not being sent from the
recorder, connect wire pair input from tone
generator to T1:T2. The warning tones from
the generator are sent to T1:T2 on a dedicated
wire pair while the speech path is sent from
T2
the AD(A)-R( ) on T3:T4 over a separate wire
pair to the recorder.
T3:T4 Connect recorder device wire pair speech
input to T3:T4.
When the recorder used supplies a warning
tone, this tone may also be sent over the
T3:T4 wire pair back to the terminal.
T5 Connect the bare end of the control cable.
T6 Connect the shielded end of the control cable. Provides common connection for control cable.
T7 Connect the bare end of the control cable.
T8
Unused
T9
Notes:
When recording in handsfree (half-duplex) mode using the built-in speakerphone, the record warning tone may not be
audible to the far-end party.
The transmit recording level is lower than the receiving voice level for intercom calls; the transmit recording level for
CO calls is normal.
Depending on the recording device(s), separate cables may be required for the warning tone and speech path. Then
connect the warning tone cables to input terminals T1 and T2 on the AD(A)-R( ) Unit (T3 and T4 are used as the
recording device input).
When remote control of the recorder is necessary, the record start/stop control is provided by connecting to T5 (or T7)
and T6 on the AD(A)-R( ) Unit. (Connecting to T5 or T7 is determined by the specifications of the recording device.)
When a warning tone is provided from the recording equipment, it should be input via T3 and T4 on AD(A)-R( ) Unit.
Do not use T1 and T2 to input beep tone.
Conversations cannot be recorded from terminals connected to an AP(R)/AP(A)-R( ) Unit.
Speakerphone calls through the HF-R( ) Unit cannot be recorded.

5. Insulate the end of the cable that needs to be shielded with
insulating tape.
Terminal Specifications
Input Terminal: T1 and T2 are enabled for tone
generating device when switches SW1-3 and
SW1-4 are OFF. When switches SW1- 3 and SW1-
4 are ON, a humming sound may be recorded due
to impedance mismatch.
Input Impedance on T1 and T2: 100K
Input Level on T1 and T2: –15 dB ~ 40 dB
Input/Output Terminal:
Refer to dip switch settings in
AD(A)-R( ) Unit Switch Settings.
When a Multiline Terminal is idle, this contact is
closed. When the Multiline Terminal goes off-hook
(using the handset, headset, or speakerphone),
this contact is open.
When recording device owner's manual specifies
start on open circuit, connect T5 and T6.
When the Multiline Terminal is idle, this contact is
open. When the Multiline Terminal is busy (using
the handset, headset, or speakerphone), this
contact is closed.
When recording device owner's manual specifies
start on closed circuit, connect T6 and T7.
