Require/Not Require CTCSS for DTMF
Each port may be configured to either require a user's signal to contain CTCSS or not require it, in order to enter DTMF commands.
This selection controls DTMF access regardless of the state of the access required for repeater access on that port. In other words, it is
possible to have a port configured for carrier squelch access, yet require CTCSS for DTMF commands to work.
1170 Port 1 no CTCSS for DTMF* 2170 Port 2 no CTCSS for DTMF* 3170 Port 3 no CTCSS for DTMF*
1171 Port 1 CTCSS for DTMF 2171 Port 2 CTCSS for DTMF 3171 Port 3 CTCSS for DTMF
Auxiliary Audio Inputs
These inputs can be used for connecting external audio devices, such as a weather receiver. When turned on, the selected transmitter
is locked on for a period selected by a programmable timer. After this timer times out, the audio is disconnected and the transmitter is
unkeyed. Which port a particular input is routed to is determined by programming commands.
1961 Turn Auxiliary Audio Input 1 ON 1981 Turn Auxiliary Audio Input 3 ON
1960 Turn Auxiliary Audio Input 1 OFF 1980 Turn Auxiliary Audio Input 3 OFF
1971 Turn Auxiliary Audio Input 2 ON
1970 Turn Auxiliary Audio Input 2 OFF
General Logic Outputs
There are 7 switched outputs that can be commanded on or off. They can also be pulsed ( 0.1 ms low, 0.1 ms open, 0.1 ms low). When
an output is high, it is actually an open collector. If you need a logic high present, you can provide a pull up resistor (up to 100 vdc).
1810 Logic Output 1 Open Collector 1850 Logic Output 5 Open Collector
1811 Logic Output 1 Low 1851 Logic Output 5 Low
1812 Logic Output 1 Pulsed (low, open, low) 1852 Logic Output 5 Pulsed (low, open, low)
1820 Logic Output 2 Open Collector 1860 Logic Output 6 Open Collector
1821 Logic Output 2 Low 1861 Logic Output 6 Low
1822 Logic Output 2 Pulsed (low, open, low) 1862 Logic Output 6 Pulsed (low, open, low)
1830 Logic Output 3 Open Collector 1870 Logic Output 7 Open Collector
1831 Logic Output 3 Low 1871 Logic Output 7 Low
1832 Logic Output 3 Pulsed (low, open, low) 1872 Logic Output 7 Pulsed (low, open, low)
1840 Logic Output 4 Open Collector
1841 Logic Output 4 Low
1842 Logic Output 4 Pulsed (low, open, low)
Note: These outputs are independent of the "Output Sinker" functions provided by the Doug Hall RBI-1 Remote Base Interface, which work in
addition to the Logic Outputs above. See the Remote Base section of this manual for details.
Extended Logic Outputs
If you have connected external shift registers as explained in the Hardware Reference section of this manual, you have a total of 64
logic outputs available to you.

y = 0 Logic low
y = 1 Logic High
y = 2 Pulsed output (low, open, low)
