HAL SYSTEM INSTALL GUIDE Administrative Rights Requirements The following table outlines which Halogen tasks require administrative rights and which do not: Requires administrative rights l Installing Halogen l Installing software updates to Halogen l Manually starting or stopping the RaneLink II service Does not require administrative rights l Running and using Halogen l Updating the HAL firmware Required Ports Communications between the PC (Halogen/RaneLink) and HAL The PC and HAL exchange information using the following ports and protocols: Local Port (PC) Any 4992 4993 4994 4994 4995 Remote Port (HAL) 22 Any Any Any Any Any Protocol TCP TCP TCP UDP TCP TCP Purpose Secure file transfer Meter control Configuration Discovery broadcast RaneLink II1 Meter data These ports are listed from the PC's perspective to aid in configuring the PC's firewall so that RaneLink and Halogen can communicate with HAL hosts on your network. HAL devices send occasional UDP broadcast messages. The RaneLink II service on the PC listens constantly for these messages and when it receives one, it does three things, if necessary: l Sets up a temporary link-local IP address (in other words, the address is cleared when the computer reboots) on the appropriate network interface card (NIC). l Adds an entry to the computer's network route table. RaneLink II maintains the list of HAL devices and it must be running for Halogen to communicate with a HAL, even if the HAL has been located by a manual search. l Opens and maintains a TCP connection with HAL so that it can receive status updates. 1A service needed by Halogen to establish a connection with HAL. 8
