ILX Lightwave LDC-3700 Series User Manual

3.2.5 <PROGRAM MESSAGE TERMINATOR>
When you send a command using the standard format, the host computer (or GPIB driver). usually puts a
<CR><NLxAEND> (carriage return-line feed-EOI) on the data bus following the command string. The IEEE-
488.2 standard requires either <NLxAEND>, <W, or <"END> as an acceptable <PROGRAM MESSAGE
TERMINATOR>,
while the <CR> is treated as <white space> (ignored). The LDC-3700 Series Controller will
accept any <PROGRAM MESSAGE TERMINATOR> shown in Figure 3.2. The LDC-3700 Series Laser Diode
Controller terminates
its responses with a <NLxAEND> (unless the user changes the terminator via the TERM
command).

If you encounter problems with GPIB communications with the LDC-3700 Series Laser Diode Controller, refer to
your GPlB dnver manual for the exact syntax of the output terminator. See also, Appendix G.
3.2.6 <PROGRAM MESSAGE UNIT SEPARATOR>
A <PROGRAM MESSAGE UNIT SEPARATOR> is used to separate sequential <PROGRAM MESSAGE UNIT>
elements (commands) from one another within a <PROGRAM MESSAGE>. The syntax for a <PROGRAM
MESSAGE
UNIT SEPARATOR> is shown in Figure 3.3.
