RTTY RTTY key input
Audio output from the transceiver
• Connect to the audio input of the TNC, MCP, or PC (or PC
interface connection).
• Audio output level is independent from the AF control setting.
• Audio output level can be changed by adjusting the value
ANO
in Menu No. 67. Set the value to a moderate audio output
level. The default value of 4 is approximately 0.5 V
is a standard modulating signal. The settings of 0 ~ 9 vary
from approximately 0 V
• Impedance: Approx. 10 kΩ.
GND Ground
Transceiver squelch control
• Connect to the squelch input of the TNC, MCP, or PC
PSQ connection interface.
• Squelch open: Low impedance
• Squelch closed: High impedance
NC No connection
NC No connection
GND Ground
PTT input for data communication
• Connect to the PTT output of the TNC, MCP, or PC
PKS
connection interface.
• Microphone audio input mutes when transmitting.
NC No connection
Audio input for data communication
• Connect to the audio output of the TNC, MCP, or PC (or PC
interface connection).
• Audio input level is independent from the microphone gain
(set with the [MIC] key).
ANI
• Audio input level can be changed by adjusting the value in Menu
No. 66. The default value of 4 is approximately 10 mVrms, which
is a standard modulating signal. The settings of 0 ~ 9 vary from
approximately no modulation to approximately 1 mVrms.
• Impedance: Approx. 10 kΩ.
GND Ground
PTT input (same as the front panel MIC connector)
SS
• During transmission, the audio input of ACC2 connector
terminal 11 (ANI) and the USB terminal are muted.
