External Foot Pedal:
When using an external foot pedal PTT accessory you will need to connect the pedal to this
connector. Polarity is not an issue, simply attach a contact closure when pushed pedal to this
input. Contact Link Communications for availability.
Audio input is routed from the PJ7 when using the external foot pedal, custom routing can be
changed based on need, contact Link Communications for details.
External 10W power speaker:
The PJ7 provides a powered speaker output that can be either Left or Right channels. When
operating the speaker you will need to attach an ex12V power supply with a 2.5mm
center pin positive supply with a current rating of 3A minimum
It is a mono output and can be configured as either Per-volume or post-volume. If pre-volume
then adjustments from the front volume control will not affect the speakers level. If post-volume
then it follows the front volume adjustment. The configuration is covered in the next section.
