10–9 Terminal and Communication Setup
Publication 2706-817
A MessageView terminal’s RS-232 port may be used as:
•
A MessageBuilder communications link port (all terminals)
•
an ASCII Trigger controlling port (Catalog Nos. 2706-M1D,
-M1N, -M1F)
•
a slave device port (Catalog No. 2706-M1D)
•
an Auxiliary Device port (Catalog Nos. 2706-M1D1, -M1N1,
-M1F1)
MessageBuilder communications link port
The RS-232 port on all MessageView 421 terminals is used in one of
its configurations as the link between the terminal and
MessageBuilder Configuration software. The RS-232 port
parameters for this link are fixed (not user configurable). See Page
5–2 for the DF1 parameters.
The section starting on Page 11–6 explains uploading to and
downloading from the MessageBuilder software. You can configure
the terminal to default to MessageBuilder configuration parameters
on power–up, see Page 10–16.
ASCII Trigger controlling port or Slave Device port
This section shows how to define runtime parameters for a terminal
controlled by an ASCII Triggering device and a terminal as a slave
device. Both devices communicate via an ASCII serial port, the main
RS-232 port.
To configure the RS-232 communications for ASCII Triggering
and Slave Device:
1. In the Terminal Setup dialog, verify the terminal type selected in
the Catalog and Version field.
