PTT In/Out
A 3.5mm jack with connections for PTT in(for example allowing an external
PTT switch) and PTT out (for example to key an attached linear amplifier).
PTT Input: short this signal to ground to initiate PTT PTT output: grounded
if TX active (eg to key external equipment)
L SPK, R SPK
Connection for left and right speakers
XLR
Input for a balanced microphone
CW Key
Duplicates the front panel CW key input
HP
Duplicates the front panel headphone input.
Mic
Duplicates the front panel microphone input
If you have a radio with front panel display, then the CW key, headphones and microphone
connections are duplicates of those on the front panel.
CW Key
3.5mm stereo jack socket. Wiring as described for the front panel connection.

speaker
connectors
External speakers should be wired
between Speaker + and Speaker -.
Use 4Ω or 8Ω, at least 2W speakers.
Open collector
pinouts:
1: GND
2: REF
3: OC7
4: OC6
5: OC5
6: OC4
7: OC3
8: OC2
9: OC1
GND = 0V
OC1-OC7 are separate open collector
outputs. Each connects to 0V when active.
REF should be connected to the highest
supply voltage used by OC1-OC7 (typically
5V or 12V)
PTT
In/Out
Connections for both PTT in and PTT out
are provided using a 3.5mm jack plug.
PTT in: connect to ground to enable PTT
PTT out: this signal is grounded when in
TX; use for keying linear amplifiers etc
