Specifies the order in which bytes are transferred in the GP-IB system.
The byte order can be set to either leftmost byte first (leftmost
rightmost byte first (rightmost
The following tables show the order in which data stored in the buffer mem-
ory’s transmission data area is sent to the GP-IB bus.
The following tables show the order in which received data is stored in the
buffer memory’s reception data area. If an odd number of bytes is received,
the last byte will be set to 00 Hex automatically.
Set this byte to 01 Hex when enhanced BASIC commands are being used in
GP-IB communications. This setting is valid in Slave mode only.
Sets the monitoring time for timeout errors during data transmission and data
reception. Set the monitor time (seconds) in hexadecimal.
The default setting of 0000 Hex specifies a timeout monitor time of 10 s.
Specifies the delimiter that will be attached to the end of the data string when
the Unit is transmitting data. Bits 08 to 11 set the EOI signal output.
