Data Communication and Host Modes
Figure 6-4: AceManager : PPP/Ethernet
•*HOSTPRIVMODE ‐ Set to 1 to enable the explicit IP addresses.
•*HOSTPRIVIP ‐ Set to the IP address you want the Raven to give to your device.
•*HOSTPEERIP ‐ Set to the IP address you want for the Raven.
•*HOSTNETMASK ‐ Set to the subnetmask, generally 255.255.255.0.
Tip: If you are using Private Mode (*HOSTPRIVMODE=1), you will need to make sure that *HOSTPRIVIP and *HOSTPEERIP are on the same subnet. If the subnet mask is 255.255.255.0, it is safe to use 192.168.x.y for each as long as the x is the same number (0 in the example screen shot above) and the y is different (1 and 2 in the example) and between 0 and 254.
Internal DHCP Server
DHCP (Dynamic Host Configuration Protocol) has become a primary component of today’s network environments. DHCP allows one server to automatically and dynamically allocate network IP addresses and other network related settings (such as subnet masks, routers, etc.) to each computer or device without the need to set up each specifically or keep track of what addresses have already been used.
In a default configuration, the Raven acts as a DHCP host to any device connected to its ports, providing that device with an IP address which can be used to communicate on the Internet. In Public Mode, that will be the IP address assigned by the cellular network. In Private Mode, that will be the IP address defined in *HOSTPRIVIP.
