Front Panel - Kenwood TS-890S Instruction Manual

1 INSTALLATION AND CONNECTION
ACC 2 Connector
Pin No. Pin Name
— NC No connection
2 RTTY RTTY control terminal (FSK key input)
Audio output
• Connect to the audio input of the TNC, MCP or PC (or PC connection interface).
• The audio output level is independent of the AF volume control knob on the front panel.
• The audio output level can be adjusted in Menu [7-09]. Adjust it to an appropriate level.
3 ANO
• When the audio output level is configured to the default value of "50" in Menu [7-09], the peak-to-
4 GND Signal ground
Squelch control output
• Connect to the squelch input of the TNC, MCP or PC connection interface.
5 PSQ
• When squelch is open: Low impedance
• When squelch is closed: High impedance
6 MET 1 Meter level output 1
7 NC No connection
8 GND Signal ground
PTT input for data communication (DATA SEND)
• Connect to the PTT output of the TNC, MCP or PC connection interface.
9 PKS • Signal can be transmitted by connecting the PKS terminal to GND.
• The PKS terminal mutes unnecessary modulation input signals during transmission.
10 MET2 Meter level output 2
Audio input for data communication
• Connect to the audio output of the TNC, MCP or PC (or PC connection interface).
• The audio input level is independent of MIC GAIN on the front panel.
• The audio input level can be adjusted in Menu [7-07].
11 ANI
• Standard modulation can be obtained with an input of approximately 10 mVrms in the default
12 GND Signal ground
PTT input
• This is the same terminal as pin 2 (SS terminal) of the MIC connector on the front panel and pin 3
13 SS • It has the same behavior as pressing [SEND] on the front panel.
• Signal can be transmitted by connecting the SS terminal to GND.
• The SS terminal mutes unnecessary modulation input signals during transmission. "Configuration
1-6
peak voltage is approximately 0.5 V p-p in the case of standard modulation signals. Altering the
audio output level between "0" and "100" changes the peak-to-peak voltage level between
approximately 0 Vp-p and 1.2 Vp-p. (Impedance 10 kΩ)
"Configuration of the Input Path of TX Audio"
setting of "50" in Menu [7-09]. Altering the audio input level between "0" and "100" changes the
standard modulation input level between approximately "almost no modulation" and approx. 1
mVrms. (Impedance 10 kΩ)
