This gives the IP address of the Q330, the attached baler is this address plus one. So, for GVA04 the Q330 is at 192.168.2.108, its Baler is at 192.168.2.109) 192.168.2.200 to 192.168.2.219 will be for other special sensor related equipment (data converters etc.)

The HPWREN Radio Path The path from the HPWREN backbone involves a local repeater station to the west(ish) of the hut, the other side of the Hemet Store. This repeater is required to get line-of-site to the HPWREN station on Toro Peak. The HPWREN statically assigned addresses associated with this link are: Toro Peak WiLan Radio 172.16.235.2 Local-repeater-radio to Toro 172.16.235.20 Local-repeater-radio to Hut 172.16.235.21 GVDA Hut WiLan Radio 172.16.235.22 GVDA Bandwidth Usage Bandwidth usage is made up of three main components. 1. Continuous near-real-time data stream is expected to be approx. 350kbps when fully operational 2. Occasional streaming video up to 2Mbps 3. Occasional interactive log-in, administration etc. which should represent low average bandwidth Thus normal everyday average bandwidth is expected to be in the <400kbps range The Netgear FVS318 box currently in use seems to support a maximum h/w bandwidth (limited by the VPN overhead processing of the router) of approx. 1.4Mbps. In order to facilitate better video quality and lower latency of data when there is larger throughput requirement, upgrading to hardware that could support >5Mbps may be considered.

WLA Networking Overview Network to the Hut is HPWREN s private subnet 172.16.195.x o Address allocation managed by HPWRE/UCSD o Network supports DHCP o Default gateway at 172.16.195.1 In the HUT network is a VPN subnet 192.168.1.x o ICS/UCSB manages all aspects of this LAN subnet o Interface router is a Linksys VPN box o Network supports DHCP (served by the CerfCube) o Router local address (default gateway for local nodes) 192.168.1.1 o WAN port on HPWREN at 172.16.195.35 (which maps to public address 198.202.xxx.xxx) In-hut Equipment The networking gear is distributed vertically on the right-hand edges of the shelves in the hut. o VPN Firewall Router o One ADAM-6520 5-port 10/100 switch o One HP ProCurve 8-port 10Mbps hub o One Netgear FS116 16-port (commercial rated, normally off but can be remotely powered-on) The biggest issue facing equipment in the WLA site is the potential operating temperature. It is expected the cooling system will keep the hut at about 70F, but outside temperatures can run to 120F. Equipment Voltage Temp Remarks Rating Linksys BEFVP41 12Vdc 32F to 131F Should be OK, temp and voltage. ADAM-6520 10 to 30Vdc 14F to 158F No worries HP Procurve 10BaseT Hub 7Vac(modified 32F to 131F Should be OK w/temp. Modified for use with ext dc/dc to run on 5Vdc) Netgear FS116 12Vdc 32F to 105F Normally off, remote power-on only if temp OK The logical and physical hook-up in indicated in the diagram below.
