MessageView terminals without daughterboards (Catalog Numbers
2706-M1D, -M1N, or -M1F) are controlled by ASCII Triggering
devices.
ASCII Triggering devices include the following Allen-Bradley
products:
•
SLC 5/03

, 5/04

Port 0
•
SLC BASIC Module
•
PLC-5 Port 0
•
other logic controllers with serial ports
•
Allen-Bradley Industrial Computers
•
any ASCII Transmitting device, including a VT100 Dumb
Terminal.
Follow this procedure to set up the MessageView terminal with an
ASCII Triggering device as the controller:
1. Download a MessageBuilder application to the MessageView
terminal.
2. Connect the terminal to the ASCII Triggering device via a 485
network. See the diagrams and pinouts in Chapter 6.
3. Access the Front Panel Editor by simultaneously pressing the up
and down arrow keys on the terminal keypad.
4. Verify that the terminal’s RS-232 port is set to ASCII Trigger. See
Page 3–3.
5. Check that the Serial Communication parameters match those of
the ASCII Triggering device. See Page 3–8.
6. Exit the Front Panel Editor. The terminal starts to run its
application.
