CHAPTER 4: Controller Operation
4.2 Serial and IEEE Terminator Substitution
The interface converter can be configured to provide serial-to-IEEE-488 and
IEEE-488-to-serial terminator substitution. This is useful when interfacing a
serial host which only issues carriage return [CR] as an output terminator to
an IEEE peripheral which expects a carriage return followed by a line feed
[CR-LF].
In this case, the serial terminator should be selected for CR Only while the
IEEE terminator is set for CR-LF. When a serial CR character is received, it is
discarded and replaced with an IEEE CR followed by an IEEE LF. In the IEEE
to serial direction, the IEEE CR is unconditionally discarded. Upon receipt of
the IEEE LF a serial CR is substituted.
The interface converter can be made totally data-transparent by setting both
the serial and IEEE terminators to be CR Only or LF Only. Refer to Chapter 3
for the proper switch settings for both the IEEE and serial terminators.
