10. ROT (ROTATOR) Jack
You may control the antenna azimuth rotation (and rotation speed) using the Function
buttons on the front panel when the optional DMU-xxxx Data Management Unit is
connected.
11. BAND DATA Jack
This 8-pin output jack provides band selection data which may be used for control of
optional accessories such as the Linear Amplifier.
12. PACKET Jack
This 5-pin input/output jack provides receiver audio and squelch signals, and accepts
transmit (AFSK) audio and PTT control, from an external Packet TNC. Pinout is
shown on page xx. The receiver audio level at this jack is approximately 100 mV (@600
Ohms).
13. RTTY Jack
This 4-pin input/output jack provides connections for an RTTY terminal unit. Pinout is
shown on page xx. The receiver audio level at this jack is at a constant 100-mV (@600
Ohms) level. FSK keying at this jack is accomplished by a closure of the SHIFT line to
ground by the terminal unit.
14. PTT Jack
This RCA input jack may be used to provide manual transmitter activation using a
footswitch or other switching device. Its function is identical to the [MOX] button on
the front panel. The same line is available at the PACKET and RTTY jacks for TNC
control. Open-circuit voltage is +13.5 VDC, and closed-circuit current is 5 mA.
15. MIC (PATCH) Jack
This RCA input jack accepts transmitter audio - either AFSK or voice - for
transmission. This line is mixed with the microphone audio input line, so the
microphone should be disconnected if using this jack and mixing is not desired. The
optimum impedance is 500 ~ 600 Ohms, and the nominal input level should be 1 mV.
16. TRV Jack
This RCA jack provides a low level RF output for use with a transverter. Maximum
output is approximately –20 dBm (0.01 mW) at 50 Ohms.
