Driver Name: Kernel GPIO Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] This driver can be used to control kernel-based GPIO interfaces, such as the GPIO pins on a Raspberry Pi. Pins are allocated such that inputs come first, followed by outputs. Further information on kernel GPIO devices can be found at https://www.kernel.org/doc/Documentation/gpio/sysfs.txt Driver Name: Livewire LWRP Audio Supported RML Commands: Switch Take ['ST'] Livewire is a distributed audio router and control system, with the components (called 'nodes') configured and controled via TCP/IP. More information can be found at http://www.axiaaudio.com/. This driver can be used to create and remove connections between audio sources and destinations via Livewire Routing Protocol (LWRP). Configuration is a matter of entering the IP address, password and base output number for each node in RDAdmin->ManageHosts->Switcher/GPIO->LivewireNodes. The driver will autodetect all other parameters from the nodes themselves. The resulting constellation of nodes can be controled with the 'Switch Take' ['ST'] RML by specifying the Livewire source stream number as the input parameter and the base output number+the slot number-1 for the output parameter. Driver Name: Livewire LWRP GPIO Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] Livewire is a distributed audio router and control system, with the components (called 'nodes') configured and controled via TCP/IP. More information can be found at http://www.axiaaudio.com/. This driver can be used to control Livewire's GPIO subsystem by means of the Livewire Routing Protocol (LWRP) with both physical as well as 'virtual' GPIO devices. Only two items need to be specified in the configuration: the IP address of the device to control and the 'Layer, with V specifying a virtual GPIO device and D specifying an actual physical one. The driver will autodetect all other parameters (e.g. the number of input and output lines) from the device itself. Driver Name: Livewire Multicast GPIO Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] Livewire is a distributed audio router and control system, with the components (called 'nodes') configured and controled via TCP/IP. More information can be found at http://www.axiaaudio.com/. This driver provides the ability to access GPIO functions from Livewire- enabled control surfaces for setups that lack a virtual GPIO device --e.g. when interfacing audio directly to a Livewire node without using a native Livewire software audio driver or audio adapter. When configuring it, the IP Address field should contain the address of the local interface to which the Livewire network is attached, while the Livewire GPIOs list should be populated with the stream number - GPIO line associations to be used. Driver Name: Local Audio Adapter Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] Switch Add ['SA'] Switch Add With Gain ['SX'] Switch Remove ['SR'] Switch Take ['ST'] It's possible to use one or more of the actual audio adapters as a switcher device using this driver. Doing so makes it possible to route audio directly from the adapter inputs to outputs, while at the same time using it for audio capture/playout in the usual manner. To configure it, set Card: to the number of the audio adapter to use and the Inputs: and Outputs: fields to the number of inputs and outputs on the card (as found in RDADmin->ManageHosts->AudioResources. Driver Name: Local GPIO Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] This driver supports a variety of GPIO devices, including: 15 Pin Joystick Port USB HID Devices MeasurementComputing GPIO Cards Joystick support utilizes the Linux Input Device subsystem. Inputs are active-low, and should be wired as follows: PinSignal2Input 14Ground7Input 25Ground10Input 312Ground14Input 412Ground In addition, you will need to connect 47 kohm resistors between the following pins: 1-3, 6-8, 9-11 and 13-15. While not strictly needed for the GPI portion of the interface to work, the kernel's analog joystick driver will refuse to initialize the port if these resistors (or a real joystick) are not present. The device name of the joystick will be one of the /dev/input/eventn devices. NOTE: There have been reports that some port models do not internally connect pin 12 to ground. The symptom of this situation will be that Inputs 1 and 2 work, but not Inputs 3 and 4. If this is the case, connecting the ground for Inputs 3 and 4 to pins 04 or 05 should remedy the problem. The following MeasurementComputing cards are supported: PCI-PDIS08 PCI-PDIS16 PCI-DIO24 The device name for the card should be /dev/gpion. The Measurement Computing PCI-PDIS08 and PCI-PDIS16 boards feature floating, opto-isolated inputs. The inputs are not polarity sensitive and may be driven by either AC or DC. The outputs are electro-mechanical relays with dry contacts.

Then, those same resources must be mapped within the Rivendell driver. For the 'ST' RML, the Logitek Engine Numbers and Device Numbers are mapped to logical Rivendell Inputs and Outputs within the Configure Inputs and Configure Outputs dialogs. For the GPO RMLs, various Logitek 'switches' (by which we mean anything that can be turned on and off, such as faders feeds, not just GPIO) are mapped to logical Rivendell GPIO lines by means of their Logitek Engine, Device and Buss numbers. Driver Name: Modbus TCP Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] This driver supports GPI devices that use the industry-standard Modbus TCP protocol at TCP port 502.

TCP connections are normally made to port 1350 on the Server Module system. Driver Name: Sine ACU-1 (Prophet) Supported RML Commands: Switch Add ['SA'] Switch Remove ['SR'] Switch Take ['ST'] Control is done by means of an RS-232C connection to the RS-232 port on the unit. Serial port parameters in RDAdmin should be set to 57600 baud rate, even parity, 8 data bits, 1 stop bit and no terminator. The ACU-1 should be set to use factory default settings. This can be done by simultaneously pressing buttons 1 and 8 on the front panel of the unit for at least one second. Driver Name: Software Authority Protocol Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] Switch Take ['ST'] Used to control devices (such as the Axia 'PathFinder' system) by means of the 'Software Authority' protocol. Control is by means of a TCP/IP connection (typically to port 9500) on the controled system. The Card parameter should be set to the 'Router Number' of the router to be controlled. Most parameters, including the number of inputs and outputs as well as the endpoint names, are autodetected by the driver. Driver Name: StarGuide III Supported RML Commands: Switch Take ['ST'] Control is done by means of an RS-232C connection to the RS-232 port on the unit. The port should be configured on the receiver to use a speed of 9600. Serial port parameters in RDAdmin should be set to 9600 baud rate, no parity, 8 data bits, 1 stop bit and no terminator. Once configured, use RDAdmin to create inputs that correspond to the StarGuide Provider and Source IDs available on the selected DVB carrier. Provider and Source ID data is available from the provider network. Driver Name: Wegener Unity 4000 Supported RML Commands: Switch Take ['ST'] Control is done by means of an RS-232C connection to one of the two RS-232 ports on the unit. If possible, use serial port number one, as the reciever uses a larger data buffer with that port. The selected port should be configured in the reciever to be of type "Terminal" with a speed of 19200. Serial port parameters should be set to 19200 baud rate, no parity, 8 data bits, 1 stop bit and no terminator. Once configured, use RDAdmin to create inputs that correspond to the DVB stream names available on the selected DVB carrier. Caution is needed when scheduling record events from the Unity4000, as the unit is capable of outputting a given DVB stream to only a single output at a time. Commanding a stream to an output will cause that stream to be silently deselected from a previously selected output. Driver Name: WheatNet LIO Supported RML Commands: GPI Enable ['GE'] GPI Set ['GI'] GPO Set ['GO'] Control is done by means of a TCP/IP connection to port 55776 on a blade.
