S-Cmd 24 SET CTCSS/DCS ENCODE LEVEL
This command allows you to select the CTCSS and DCS encode modulation level to the repeater transmitter. A digital pot with
64 positions (0 to 63) controls this level. This command will also accept “*” (up) and “#” (down) commands for adjusting the
digital pot one step at a time.
The DCS encoder audio can be mixed with the voice audio or routed directly to the transmitter modulator via J1 pin 11. Some
modulators require a separate input for DCS audio. Jump JP4 pin 1-2 to select J1 pin 11 output, or jump JP4 pin 2-3 for mixing
DCS with the voice audio. See the assembly drawing in section 17 for additional details and the location of this jumper.
SYNTAX: 24 [Encoder] [Level]
READ BACK: 24 [Encoder]
STORAGE: RAM/EEPROM
PARAMETERS: Encoder 0 = CTCSS: This is the CTCSS encoder, used to encode CTCSS tone to the transmitter.
Encoder 1 = DCS: This is the DCS encoder, used to encode DCS codes to the transmitter.
Level 0-63 = Numeric pot positions (0 = Minimum value and 63 = Maximum value)
Level * = Raise pot by one step only
Level # = Lower pot by one step only
DEFAULT: CTCSS = 15
DCS = 10
EXAMPLE: 24 0 * Raises CTCSS pot setting by one step
24 1 # Lowers DCS pot setting by one step
24 1 15 Moves DCS pot to position 15
S-Cmd 25 DCS TX/RX DATA POLARITY CONTROL
Depending on your repeater’s receiver and transmitter, you may have to change the polarity of the DCS TX/RX data. If the
controller will not decode DCS data, change the RX polarity. If your radio will not decode DCS data from the repeater, change
the TX polarity.
SYNTAX: 25 [TX/RX] [Pol]
READ BACK: 25 [TX/RX]
STORAGE: RAM/EEPROM
PARAMETERS: TX/RX 0 = TX (Encode): This is used to adjust the DCS encoder data polarity
TX/RX 1 =
RX (Decode): This is used to adjust the DCS decode data polarity.
Pol 0 =
Positive: The data polarity is NOT inverted
Pol 1 =
Negative: The data polarity is inverted.
DEFAULT: TX = 0 (Positive)
RX = 0 (Negative)
EXAMPLE: 25 1 0 Set RX polarity to Non-inverted
S-Cmd 26 CTCSS and DCS AIR TIME
This command is used to set up and read back the total user airtime for each CTCSS/DCS tone/code. You can reset one or all
timers to zero, preset a timer to a pre-selected time or read back the current total time. Each CTCSS/DCS tone and code airtime
is tracked even when that tone or code is not enabled. You will be able to monitor activity for tones that you are not currently
using. Each airtime counter will roll over to zero after 1000 hours of airtime.
SYNTAX: 26 [Tone] [Time]
READ BACK: 26 [Tone]
STORAGE: EEPROM
PARAMETERS: Tone 0 = All tones, Tone 1 though 155 (See table in S-Command 20)
Time 0 = Reset timer, Time 1 through 59,999 (Minutes) = Preset timer
DEFAULT: All tones = 0 (Reset)
EXAMPLE: 26 000 0 Reset all tones and codes
26 020 0 Reset 127.3 Hz tone
26 013 Read back 100.0 Hz airtime
26 055 100 Preset DCS 032 code to 100 minutes.
