S-Cmd 00 SIGNAL POLARITY
This command controls the polarity of the NSQ, TSQ and PTT signals. It is also used to set the type of RX audio that is
connected to the controller (Emphasized and Non-emphasized audio).
As for signal polarity, setting the data value to 0 indicates an active low signal. Setting the data value to 1 indicates an active
high signal. The factory default is active low on all signals, which is most common in many applications.
As for RX audio type, this controller will support both flat (discriminator) audio and emphasized audio. When connecting the
controller to a audio source like EchoLink or IRLP, you will want to use emphasized audio.
SYNTAX: 00 [Item] [Mode]
STORAGE:
RAM/EEPROM
PARAMETERS: Item 0 = NSQ (Noise Squelch), Mode 0 = Active Low, Mode 1 = Active High
Item 1 = TSQ (Tone Squelch) , Mode 0 = Active Low, Mode 1 = Active High
Item 2 = PTT (Push To Talk) , Mode 0 = Active Low, Mode 1 = Active High
Item 3 = RX Audio Type (Tone Squelch) , Mode 0 = Flat (Discriminator), Mode 1 = Emphasized
DEFAULT: Item 0 through 3 = Mode 0
EXAMPLE: 0001 Change NSQ input to active High
0031 Change RX Mode to Emphasized audio
S-Cmd 01 PORT RX REPEAT MODE
This command controls the conditions that are required to key the repeater and pass audio from the receiver to transmitter. This
command does not affect the conditions when audio is sent or received from the auxiliary port. When the port repeat is in mode
0 (Off), audio is not routed from the receiver to the transmitter. When the controller port repeat is in mode 1, NSQ controls
when audio is pass from the receiver to transmitter.
Modes 1 and 3 are used in normal repeater operation. Modes 2 and 4 are for special use operations. When using this controller
as a remote base or non repeating link, this command should be set to mode 0.
SYNTAX:
01
[Mode]
STORAGE:
RAM/EEPROM
PARAMETERS: Mode 0 = Repeat Off.
Mode 1 = NSQ, Noise Squelch will switch audio. TSQ is ignored.
Mode 2 = TSQ, Tone Squelch will switch audio. NSQ is ignored.
Mode 3 = NSQ and TSQ, both Noise and Tone Squelch are required to switch audio from the receiver to
the transmitter.
Mode 4 = Open squelch. The receiver audio is routed to the transmitter at all times. Both NSQ and TSQ
are ignored.
DEFAULT: Mode 0 (Repeat audio is Off)
EXAMPLE: 01 0 Turns off (disables) the repeat function of the controller
01 3 NSQ and TSQ are required to repeat audio from the receiver to the transmitter
S-Cmd 02 RX GAIN ADJUST
This command is used to adjust or fine tune the receiver audio level. Coarse level adjustments are made with the manual
potentiometer on the circuit board. After that, fine or remote adjustments of the receiver audio level can be made with this
command.
SYNTAX:
02
[Level]
STORAGE:
RAM/EEPROM
PARAMETERS: Level 0 to 24 = +/- 12db.
Level 12 = 0db.
DEFAULT: Level 12 (0db)
EXAMPLE: 02 11 Reduce the receiver gain
