PRI offers Automatic Meter Reading (AMR) via Ethernet Local Area Networks The Delta Plus LAN modem allows the use of onsite Ethernet Local Area Networks (TCIP) for Automatic Meter Reading (AMR) of utility meters, as well as for data collection and remote logging applications. The new AMR solution is suitable for use with a wide range of PRI OFGEM approved meters or panel mounted sub metering products and can be interfaced to PRI PACTLAN meter networks. For the first time it is now economically and technically viable to use LANs as a transport media for large scale telemetry traffic. In many cases, with a single LAN connection to a customers designated network access router, it will be possible to recover data from hundreds of remote meters. The benefits of this method of data collection could be considerable both in terms of cost and speed. Costs of Automatic Meter reading will be reduced since the LAN collection will usually incur virtually no variable costs, reduce the number of central dial-out modems will be and associated telephone lines will be reduced, whilst also removing the need for dedicated telephone lines at remotely monitored sites. To ensure maximum compatibility with host equipment, the Delta Plus LAN modem uses the same industry standard AT command interface as telephone modems. This makes it appear to the host as a modem. Outgoing calls are routed to an IP address instead of a telephone number. Incoming calls are handled in the normal way. The Data Plus LAN modem emulates standard telephone modem, communicates at data rates up to 115.2k bps, uses standard RJ45 & Industry standard Cat 5 Ethernet cable plus a 25 way D-type socket interface. The unit has flexible power supply via the D socket or an external PSU and offers a standby mode with low current drain. Installation is easy plug an play and is compatible with most modem style interfaces. The compact and cost effective solution offers remote configuration and diagnostics to minimise site visits. The Delta Plus LAN modem reduces data recovery costs, speeds collection times, is easy to interface to existing equipment and is an ideal replacement for fixed line modems. |
