SANO
Audio Output for the Sub Band Audio
Sends the audio signal to external devices, such as TNC, MCP and PC.
• The audio output level cannot be changed with the
AF control on the front panel.
• Audio output level can be changed in Menu 7-11, "Sub Band Audio Output Level (ACC 2)".
0 Vp-p audio signal is transferred with “0” configured for the audio output level, 0.5 Vp-p audio signal
is transferred with “50” as the default, and 1 Vp-p audio signal is transferred with “100” configured.
(Output Impedance: 10kΩ)

RTTY (FSK keying terminal)
• The keying polarity can be changed in Menu 2-07, "FSK Keying Polarity".

MANO
Audio Output for the Man Band Audio
Sends the audio signal to external devices, such as TNC, MCP and PC.
• The audio output level cannot be changed with the
AF control on the front panel.
• Audio output level can be changed in Menu 7-10, "Main Band Audio Output Level (ACC 2)".
0 Vp-p audio signal is transferred with “0” configured for the audio output level, 0.5 Vp-p audio signal
is transferred with “50” as the default, and 1 Vp-p audio signal is transferred with “100” configured.

MSQ
Sends the main band squelch control signal.
• Connects to the squelch input terminal of the TNC or MCP, or the interface terminal for connection to
a PC.
• Open Squelch: Low impedance
• Tight Squelch: High impedance

PKS
PTT Input for data communication (DATA SEND)
• Connecting to the PTT output interface for the TNC, MCP and PC connection
• Shorting the PKS pin to Ground starts the transmission.
• During transmission using the PKS pin, mutes the unnecessary modulation input signal. INPUT

SMET
Sends the sub band meter levels.
Type of output signal and its output level can be selected from Advanced Menus 1, "Indication Signal
Type (Main Band)", and 3, "Output Level (Sub Band)".

ANI
Audio input for data communication
• Connects to the audio output of the TNC, MCP, PC (or the interface for connection to a PC).
• The audio input level cannot be changed with the
MIC control on the front panel.
• Audio input level can be changed in Menu 7-06, "ACC2: Audio input Level".
If “0” is configured, the transceiver transmits nearly without modulation. With the default of “50”,
the transceiver transmits with standard modulation by 10 mVrms input. If “100” is configured, the
transceiver transmits with standard modulation by 1 mVrms input. (Input Impedance: 10kΩ)

SS
PTT Input
• Has the same function the SS terminal assigned to 2nd pin of
MIC connector on a front panel and
3rd pin of REMOTE connector on a rear panel.
• The same behavior as when
[SEND] on the front panel is pressed
• Shorting the SS terminal to Ground starts the transmission.
• During transmission using the SS pin, mutes the unnecessary modulation input signal. INPUT LINES
