OPTIONAL EQUIPMENT
1.0 Variable Attenuator (MVAT)
The Ultra Laser System may be equipped with an adjustable variable
attenuator. Both motorized and manual versions are available. The
assembly is contained within the Laser Head and is isolated from dust,
moisture and other external environmental factors. The motorized version
is controlled by one of the following options:
•
5 volt analog signal.
•
RS-232 serial cable.
Any communications program such as HyperTerminal is acceptable for the
RS-232 communications. A standard 9-pin RS-232 cable (not included with
system) is required.
Before using the MVAT:
1. Set up a computer or other terminal device to control the MVAT
remotely via RS-232 serial communication.
2. Set up your laser system following the steps in
.
MVAT SETUP AND CONNECTIONS
1. Turn off system power.
2. Disconnect the existing I/O cable from the back panel of the ICE450,
if one is present.
3. Connect the supplied MVAT I/O cable to the ICE450 I/O port.
4. Connect the two I/O connectors to the Laser Head I/O ports.
5. Connect the MVAT “pigtail” to the RS-232 COM port on your
computer/terminal device using a standard 9-pin RS-232 serial cable
(not included).
Note:
Do not plug the MVAT serial cable into the ICE450. The MVAT is
controlled by a user supplied computer, not through the ICE450.
Note:
The RS-232 protocol is used to communicate with the MVAT. The
MVAT utilizes a “minimum three wire” configuration. See the RS-232 wiring
diagram in Figure 28. Pins shown in red are required to be used.
