Use the following menus to select a module by
name or function:
Chameleon Ordering Guide
Step 1: Choose Base Modules in the Node Select the networking, I/O,
operator interface, etc. module(s) that you require for your node. Keep in mind
that most modules contain a microprocessor and are programmable -- think
about how you would like to distribute your field connections and algorithms
throughout the node.
Step 2: Select Power Supply Modules
Based on the required power draw from
the modules in step 1 and available power source, select one or more power
supplies for your node. The ACP-1 and
DCP-1 can each
provide up to 25W of power. Multiple power modules (up to three) can
be combined to increase the available power. As a rule of thumb, if
you have four or less modules in your node you can safely assume that you
only need one power supply. If you are using more than four modules,
use the Power Draw Calculator to determine the number of power supply
modules required. Add additional power supply modules if you need
redundancy.
Step 3: Pick Mounting Method
The Chameleon enclosure supports three
different types of mounting methods: Din Rail, Wall/Panel Mount, and Shock
and Vibration Mount. Note that you will require (n+1) x 2 number of
feet (where n is the number of modules) for your node.
Step 4: Put it all Together
Backplane Cables: Each junction between
adjacent modules requires a backplane ribbon cable. The node will
require n-1 backplane cables (where n is the number of modules in your
node.)
End Caps: Each node must contain two end caps to environmentally seal the
ends of the enclosure. End caps are reversible so one part can be used
on either side.
Chassis Ground Straps: Each power supply will require a chassis ground
connection. If you are mounting to a grounded surface then it is
recommended that you connect a braid/strap from the external ground stud directly
to the surface. There are also chassis ground wire terminals located
on the power supply's wiring hub. If your system is to be MIL-STD 461E
qualified then you must add a chassis ground strap on every module in
the node.
IrDA Wireless Interface: A link from a PC or laptop to Chameleon is required
to (initially) program and interface with the device. In most cases, this
link is in the form of wireless IrDA using an adaptor. The IrDA
adaptor plugs into your computers RS-232 serial port. You may use a
USB to RS-232 converter (and connect the RS-232 IrDA adaptor) if a USB
connection is desired. Note: Do not use a native USB based IrDA
adaptor -- the adaptor must be RS-232.
Wiring Accessories: It is recommended that all field wire connections be
terminated with a ferrule or blade lug before insertion into the terminal block.
