Note The GP-IB Interface Unit will complete reception when any of the following
Specifies the delimiter that indicates the end of the data string when the Unit
is receiving data. Bits 08 to 11 specify whether or not the EOI signal is being
used to complete reception.
Sets the number of bytes in a complete reception. The setting range is 0001
to 0200 Hex (1 to 512 bytes.) The “number of bytes to receive” setting is effec-
tive regardless of the reception delimiter specification set in m+4.
conditions has been met.
These conditions are processed in the order listed above. For example, recep-
tion will be completed immediately if the specified number of bytes is received
before the EOI signal is detected.
These settings determine which external interrupt task (if any) is started in the
CS-series CPU Unit when the GP-IB Interface Unit is operating in Master
mode and an SRQ message is received. These settings are effective in Mas-
ter mode only.

The GP-IB Interface Unit is allocated 10 words within the Special I/O Unit area
(CIO 2000 to CIO 2959) of the CPU Unit’s CIO Area. The following table
shows the actual word addresses allocated to each Unit based on the unit
number (0 to 95) set on the front of the Unit.

Attach the user-set code (03 Hex) and output EOI.
Reception is completed when CR + LF is received and the EOI
