RS-232 Terminator Byte
User’s Guide 5-87
The RS-232 Terminator Byte Programming mode
contains 2 shortcuts: A and B. After entering this
programming mode you can go directly to a specific
parameter by scanning the appropriate shortcut Hex tag
(Hex A or Hex B). This eliminates the need to enter all
parameters when only one needs changing.
Figure 5-14 shows an example of a completed RS-232
Terminator Byte programming worksheet. This example
shows the Terminator Byte enabled and ASCII code
EOT (0D Hex) transmitted as the Terminator Byte.

You can enter the RS-232 Terminator Byte parameters in
one of two ways. One is to enter all the parameters in
the RS-232 Terminator Byte Programming mode, the
other is to enter only specific parameters by using
parameter shortcuts.
