HelvarNet Overview

HelvarNet is an Ethernet I/O protocol that allows third-party devices (e.g. AV equipment) to query and control a 905/910/920 router system, as well as perform some basic system configuration, over an Ethernet ( TCP Stands for Transmission Data Protocol. TCP is one of the core protocols of the Internet Protocol Suite. It was one of the two original components, with Internet Protocol (IP), of the suite, so that the entire suite is commonly referred to as TCP/IP. Whereas IP handles lower-level transmissions from computer to computer as a message makes its way across the Internet, TCP operates at a higher level, concerned only with the two end systems, for example, a Web browser and a Web server. In particular, TCP provides reliable, ordered delivery of a stream of bytes from a program on one computer to another program on another computer. (See also TCP/IP)./IP) connection. It is a published standard that provides a set of rules for communicating with a Helvar lighting system A network of client PCs, routers, control devices, control gear, and lamps.

The third-party device A physical item with which you can interact, either directly or via Designer. may communicate with one or more routers in the system, provided it knows the IP address Internet Protocol (IP) is a four-byte address that uniquely identifies the device to which it is assigned on the network. This address conforms to IPv4 standard. Each router broadcasts packets of information via IP. A router acts only upon instructions sent to its unique IP address. of each router, in order to communicate with the lighting system.   

Protocols

The following TCP/IP protocols are supported by HelvarNet:

TCP  connection created and accepted by router.

UDP User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite, the set of network protocols used for the Internet. With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths.  incoming and outgoing.

What are the requirements?

• The interface provides you with a means of interacting with the lighting system. It is up to you to develop and program your third-party device in order to achieve this communication.

• If you want to send commands to the router system from the third-party device, then the third-party device must be able to instigate a TCP connection with a Helvar router or send UDP messages to a Helvar router (this is not required for the router system to control the third-party device).

• To establish a TCP connection and therefore communicate with the router, the third-party device is required to connect to listener port number 50000.

• To send TCP messages from the router to the third-party device, the router connects to a listener port provided in the third-party device. It is recommended that this listener port is in the range from 49152 to 65535. For more information, see Routing Entries and Schedules. For information about how to send UDP messages, see Scene Triggered Ethernet I/O.

• When using the UDP protocol, the third-party device is required to send a message to destination port number 50001 in the router.

• To send UDP messages from the router to the third-party device, it is recommended that the destination port in the third-party device is in the range from 49152 to 65535. For more information, see Routing Entries and Schedules . For information about how to send UDP messages, see Scene Triggered Ethernet I/O.
