You can type in any PL tone to the tenth of a cycle or use weird tones. Or strange DPL codes, even inverted. There are probably others.
I suggest that if you use DPL that you stick with the "standard" list of codes. Using strange codes generates an offset on the transmitter, and that can make the transmiter to apper to be off frequency, which can cause the receiving radio to distort the audio whaich can not open the squelch.
A list of the legitimate DPL codes is here. A few notes about the M mobile radio: Despite the model number the M and the full duplex R module are totally different animals. The M is a low duty cycle mobile. It is The M can be programmed using the same RSS all the way down to Note that the 4-channel M cannot do channel steering, the higher channel count models can. The R module has a internal controller that supports a number of programmable features.
Here is a short-form description of each accessory connector pin. A number of the pins can be programmed for various functions. Several pins are electrically bidirectional but are programmed as either in or out. Neither pin 1 nor 16 is ground or can be grounded. Connect an external 8-ohm speaker to pins 1 and Operation of the speaker is dependent on the presence of a volume control, which is part of the optional external control panel.
This path is enabled when the external microphone PTT is active grounded. This pin is pulled low via a diode when the front panel mic PTT is pulled low to allow sensing of mic PTT by an accessory. Maximum current is 0. Refer to the "Programmable Pins" section below. May be programmed using RSS to bypass the limiter. Refer to Refer to the "Programmable Pins" section below.
In Repeater Mode of operation, activating this pin knocks down disables the repeat function and places the unit in Base Station Mode. Minimum load resistance: 5k ohms.
Default is de-emphasized and squelch muted. May be programmed for flat and unmuted using RSS. Note that the maximum current available is 0. Expanded Accessory Connector Programmable Pins: Pins 4, 6, 8, 9, 10, 12, and 14 on the accessory connector are programmable. The function of each pin can be assigned using the RSS.
Information on the available functions and how to program them is contained in the RSS help screens and in the files in the Appendices section of the manual. The programming of these pins is very similar to the GM Pin 4 is an output only. It provides an active high to the Pins 6, 10, and 9 are inputs only. They are normally pulled high inside the radio to 5 V dc via 4. To activate any of these input pins, it should be pulled low to within 0.
Pins 8, 12, and 14 may each be programmed as either an input or output. If programmed as an input, the pin is pulled high to 5 vDC via 4. To activate the input, it should be pulled low to within 0. If programmed as an output, the pin is normally pulled high to 5 V dc via 4. When enabled, the output goes active low. Maximum sinking current is 50 mA. The R radio module, like the GM, supports "channel steering" through the accessory connector.
The number of pins you program for channel select determines how many remotely selectable channels you can access with a binary select mechanism. Basically two pins gives you 4 selectable channels, three pins gives you 7, four gives you Each channel select pin turns into a binary coded input that allows you to select any of the possible 16 channels by grounding the appropriate input lines assuming you've programmed the pins for active-low inputs.
Channels 1, 2, 4, 8, or 16 may be selected by grounding Channel Select line 1, 2, 3, 4, or 5 respectively. All other channels are selected by grounding multiple select lines. If you release all of these lines, the pins float high and the radio reverts to the channel selected by the front panel if present. If you select a channel that does not exist i.
First of all, the unit has an internal controller and that needs to be disabled in the programming software if you are going to use an external controller.
The actual interfacing is done through the 16 pin accessory connector. The programmable pins are very similar to the GM and program similarly. Pin Description 2 Repeat audio from controller to the R transmitter.
This pin can be programmed to bypass the limiter. Learn More — opens in a new window or tab Any international shipping and import charges are paid in part to Pitney Bowes Inc.

To see which pin functions the accessory connector of the R should be programmed for, for all the available controllers, click here. Basic repeater interfacing circuitry and control are features of the R transceiver.
For advanced features, external controllers may be added inside the repeater housing. This can be important in systems using the X-Pand feature.
