3. More Space or Tab Characters
In the command descriptions, parameters are shown isolated by spaces. One space
after a command is necessary (unless no parameters are necessary). All other spaces
are optional. Spaces are put in for clarity in the manual and can be left in or left out
as necessary. You can put more spaces or tabs between parameters as necessary.
More spaces in a parameter are typically not permitted. You can have more spaces
between a number and its related multiplier or unit.
4. Terminators
Table 5-5 summarizes the terminator characters for both the IEEE-488 and the RS-
232 remote interfaces.

IEEE-488 interface:
The Product sends the ASCII character Carriage Return with the EOI
control line held high as the terminator for response messages. The
Product recognizes the subsequent as terminators when found in
incoming data:
• ASCII CR character
• All ASCII character sent with the EOI control line asserted
RS-232 interface:
The Product sends a Carriage Return (CR) character as the terminator for
response messages. The Product recognizes the subsequent as
terminators when found in incoming data:
• ASCII CR character
• ASCII LF character
5. Incoming Character Processing
The Product processes all incoming data as follows:
• The most significant data bit (DIO8) is ignored
• All data is read as 7-bit ASCII
• Lower case or upper case characters are accepted, with lower case changed to upper
case before they are used.
