Section 1. Setting Up the Network and Communicating with the Datalogger
1-4 PC208W, Version 3.3, Instruction Manual
Review the example below:
The first item shown on the Device Map above is COM1

it is considered a
parent component. The CR500 under it is a child. This communications link
could be for direct connection from a desktop PC's COM1 port to the CR500.
The Modem1 connection is a link from the PC's COM1 port that has a phone
modem connected to it, an RF modem connected to the phone modem, and a
CR10X at the other end (remote RF modem is assumed) and a storage module
connected to the CR10X. COM2 is a similar example, with a CR10X
connected to COM2 through a phone modem (remote phone modem is
assumed).
Following are some hints which may help when setting up your Device Map.
•
When you choose Add Device, a two column popup screen appears. The
device which you want to add should be chosen from the left-hand
column; the component which you want for the parent device should be
chosen from the right hand column. PC208W will only allow you to
choose valid parent components for each device; other devices are grayed
out.
•
Add your COM port first, and then attach each component in the order that
it physically appears in your communications link.
•
PC208W recognizes that modems are used in pairs

one at the computer
and one at the datalogger. Therefore, once you attach a modem to the
COM port, you do not have to add another modem for the datalogger site.
•
Each device can be given a unique name. This can be helpful if you have a
large network of datalogger sites and you want to remember which
connections are for which sites. Device names can be edited by typing in a
new entry directly in the device’s Name field on the Hardware, Data
Collection, or Schedule tab.
•
If you need to change the logical order of a site's communication link, you
can select a component with the mouse pointer and drag it to a new
location. If PC208W is unclear of the connection to be made it will ask
you to select whether the device should be connected as a child component
or on the same level. If the device you are moving has child components,
these will be moved along with their parent device.
