Per Line Setup Window—Local, Tone, and Console Mode
LAM Level Field - Local, Tone, and Console Modes
The LAM Level field identifies the threshold, in dB, at which the radio/line unmutes and sends RX packets to the Ethernet.
The range for this field is -50 to +10dB.
LAM Time Field - Local, Tone, and Console Modes
The LAM Time field identifies the amount of time, in seconds, the LAM level can drop below the threshold without action
from the IP-223. It allows small gaps in the audio sequence.
The range for this field is 0 to 60 sec.
The Monitor Relay field provides the IP-223 the ability to decode a valid Ethernet packet and provide a relay-contact output
to turn off the sub-audible-tone-decoder circuit in the radio receiver. This allows the console operator to monitor the line for
other users before transmission (required by FCC regulations on stations equipped with CTCSS).
Available selections for this field are:
Reset with PTT - The monitor relay is activated from the time the monitor tone sequence is received until the next PTT
operation.
On except PTT - The monitor relay is activated at all times except when PTT is active, whether the monitor function
tone is received or not.
Timed - The monitor relay is activated for the amount of time, in ms, entered.
If an Options field cannot be selected, the particular option is not available for the line being configured.
Supervisor Check Box - Tone and Console Modes
The Supervisor check box indicates the Supervisory I/O pin (DIG1, pin 21 of the DB25 connector) is enabled. If selected,
parallel console supervisory control is enabled and control of the radio can be seized from other consoles.
Cross Mute Check Box - Tone and Console Modes
The Cross Mute check box indicates the crossmute I/O pin (DIG0, pin 8 of the DB25 connector) is enabled. If selected,
parallel console crossmute control is enabled. Crossmute is used to mute the parallel consoles during a parallel transmission.
Full Duplex Check Box - Local, Tone, and Console Modes
The Full Duplex check box indicates full-duplex audio is supported. If selected, full-duplex (TX and RX transmission) audio
is allowed.
RxAGC Check Box - Local, Tone, and Console Modes
The RxAGC (Receive Automatic Gain Control) check box indicates radio RX audio includes an AGC. If selected, an AGC
step is added to the radio RX audio. This results in a more consistent radio RX audio transmission by increasing the level of
low audio and decreasing the level of loud audio.
