Setup Information

On With PTT Radio Button
The On With PTT radio button indicates whether or not CTCSS is generated only when PTT is activated.
Tape Output Radio Button
The Tape Output radio button indicates whether or not CTCSS is generated. If selected, no CTCSS is generated. This audio
output is used as an analog sum of RX and TX audio for the line. The output port is a single ended capacitor coupled.
TX Delay Field
The TX Delay field identifies the delay, in ms, of TX audio. When TX Ethernet packets arrive, the PTT relay is closed and TX
audio is delayed for the specified time. This provides the ability to overcome timing issues involving repeater attack time or
trunking (clear to talk) delays.
The range for this field is 0 to 2000ms.
RX Delay Field
The RX Delay field identifies the amount of time, in ms, RX audio is recorded and stored. RX audio is constantly recorded by
the IP-223 and when a COR or LAM triggered detect occurs, the IP-223 goes back the specified time of delay to start
generating Ethernet packets. This provides the ability to prevent lost first syllables using COR or LAM.
The range for this field is 0 to 1000ms.
Squelch Tail Delay Field
The Squelch Tail Delay field identifies the amount of time, in ms, the RX audio is muted after PTT occurs. This provides the
ability to overcome squelch tail ping-pong in crosspatch modes by muting the radio RX input after PTT occurs.
The range for this field is 0 to 5000ms.
