For example:
Q: How do you add IP addresses for devices?
A: You don't. However you do assign IP addresses to your
communication devices. Because viewLinc communicates
using COM ports, attaching devices to the network using
Ethernet/IP addresses requires the use of a networking
device. vNet or Digi devices create virtual COM ports that
allow devices to communicate with viewLinc using Ethernet.
We recommend that you do not use dynamic IP address for
your device; instead, use a reserved or static IP address
(obtained from your IT department). IP addresses are
assigned to vNet or Digi devices during driver configuration.
Refer to the Vaisala Veriteq Quick Start Guide for vNet or Digi
devices for installation instructions. For more about vNet, see
www.vaisala.com/lifescience-hitech. For more about Digis,
see www.digi.com.
Q: How does viewLinc know which devices (with attached devices)
are assigned to it?
A: It doesn't. Your network devices aren't 'assigned' to
viewLinc; rather, viewLinc monitors the network for devices
attached to COM ports. As mentioned, viewLinc software
communicates via COM ports. Installing a network device
creates virtual COM ports which are monitored by viewLinc.
To see which COM ports (virtual or other) are assigned to a
vNet or Digi device, use Device Manager:
1
Open Device Manager (From Start, choose Control
Panel | Administrative Tools | Computer Management.
Device Manager is on the left hand side).
2
Once Device Manager is open, expand Ports (COM &
LPT) to see which COM ports are connected to which
devices. By default, vNet devices are named CDL-VNET-
P - model name; Digi devices are named Digi xxxxx
(where x is the serial number of the device).
