NAME
owmon - Monitor for owserver settings and statistics
SYNOPSIS
owmon -s owserver-tcp-port
DESCRIPTION
1-Wire 1-wire is a wiring protocol and series of devices designed and manufactured by Dallas Semiconductor, Inc. The bus is a low-power low-speed low-connector scheme where the data line can also provide power. Each device is uniquely and unalterably numbered during manufacture. There are a wide variety of devices, including memory, sensors (humidity, temperature, voltage, contact, current), switches, timers and data loggers. More complex devices (like thermocouple sensors) can be built with these basic devices. There are also 1-wire devices that have encryption included. The 1-wire scheme uses a single bus master and multiple slaves on the same wire. The bus master initiates all communication. The slaves can be individually discovered and addressed using their unique ID. Bus masters come in a variety of configurations including serial, parallel, i2c, network or USB adapters. OWFS design OWFS is a suite of programs that designed to make the 1-wire bus and its devices easily accessible. The underlying priciple is to create a virtual filesystem, with the unique ID being the directory, and the individual properties of the device are represented as simple files that can be read and written. Details of the individual slave or master design are hidden behind a consistent interface. The goal is to provide an easy set of tools for a software designer to create monitoring or control applications. There are some performance enhancements in the implementation, including data caching, parallel access to bus masters, and aggregation of device communication. Still the fundemental goal has been ease of use, flexibility and correctness rather than speed. owserver owserver (1) is the backend component of the OWFS 1-wire bus control system. owserver (1) arbitrates access to the bus from multiple client processes. The physical bus is usually connected to a serial or USB port, and other processes connect to owserver (1) over network sockets (tcp port). Frontend clients include a filesystem representation: owfs (1) , and a webserver: owhttpd (1). Direct language bindings are also available, e.g: owperl (3). There are also many light-weight clients that can only talk to owserver (1) and not to the 1-Wire bus directly. They include shell and multiple language modules (perl, Visual Basic, python,...) owserver protocol All the owserver (1) clients use the owserver protocol for communication. The owserver protocol is a well documented tcp/ip client/server protocol. Assigned the "well known port" default of 4304. owmon owmon (1) is connects to owserver (1) and displays the bus structure and contents of the interface, statistics and settings directories.
SPECIFIC OPTIONS
-s TCP port or IPaddress:port for owserver The tcp port (IP:port) for the "upstream" owserver.
EXAMPLE
If owserver (1) is started: owserver -p 4304 -d /dev/ttyS0 owserver on tcp port 4304 and connects to a physical 1-wire bus on a serial port. You can monitor owserver (1) with owmon -s 4304 /
PLATFOMS
owmon (1) is a pure Tcl/TK program and will run whereever Tcl/TK is available (Windows, Macintosh, Linux, Unix)
