serialportlist

The serialportlist object exposes the available serial ports on a BrightSign player.

serialportlist IDL

interface SerialPortList {
    Promise<array> getList();
};

Object Creation

To create a serialportlist object, first load the brightsign/serialportlist module using the Require() method. Then create an instance of the serialportlist class.

var SerialPortListClass = require("@brightsign/serialportlist");
var serialPortList = new SerialPortListClass();

serialPortList

Use this interface to get a list of the available serial ports (an array of serial port objects).

getlist()

Promise<array> getList()

The following table is an example of what getList() might return:

[{"fid":"UART:0","path":"/dev/ttyS0"},
{"fid":"UART:1","path":"/dev/ttyS1"},
{"fid":"USB:B/2.0","path":"/dev/ttyUSB0","pid":24577,"vid":1027},
{"fid":"USB:B/4.0","path":"/dev/ttyUSB1","pid":24577,"vid":1027}]

fid: The friendly ID that indicates the physical location on the player of a port
vid, pid: The vendor and product ID (for USB devices only)
path: The native path suitable for passing to the SerialPort constructor

The roDeviceInfo GetUSBTopology() method contains information about USB devices (though fids used in that method don't contain USB: prefix), and details about the interpretation of the fid field.

This is the standard port enumeration of serial devices:

Most standard serial devices (including the USB-serial port on the LS424) enumerate on port 0.
To communicate with the serial port of an OPS display (for example, with the HO523), use port 1.
