U511 User’s Manual Parameters
Version 1.1 Aerotech, Inc. 4-15
4.4. Page 4: GPIB/IEEE-488 Setup
Parameters in this section address the setup of the GPIB/IEEE-488 port.
4.4.1. “GPIB address” (0-30)
U511 controllers can be linked through the GPIB bus. Each controller would then be
given an address of its own. Parameter 626 is the communications address of the U511
GPIB port. The value may range from 0 to 30. The default value is 2.
4.4.2. “EOS character”
The character represented by parameter 627 should terminate all strings received by the
U511. All strings returned by the U511 are terminated by this character and EOI. The
default has a decimal value of 10 and a hexadecimal value of 0x0A (line feed [LF]
character).
4.4.3. “Parallel Pol Response bit” (0-NONE or 1-8)
Parameter 628 determines how the U511 responds to a parallel poll. If a service request is
pending, the specified bit, either 1 through 8 will be read as logic 1. If this parameter is
set to 0, the U511 does not respond to the parallel poll. The default value is 0.
4.4.4. “Time out” (seconds)
Parameter 629 is the time out setting for the bus. The default setting is 0.
4.4.5. “Default configuration”
The number of parameter 630 specifies the operation of the remote interface after a power
up condition. See Chapter 6: Remote Mode Operations for more information. This
parameter can range from 0 to 8,388,607 and the default value is 0.
Any communication parameter can be entered in hexadecimal format as in 0x123 or
in decimal format as in 163.
