IP-488 is part of the Industry Pack™ family of modular I/O components. It provides talker, listener and controller access to the IEEE-488 instrumentation bus (GPIB). IP-488 is compatible with IEEE-488.1 and IEE-488.2.
IP-488 is a straight forward implementation of National Instruments' NAT9914A. The NAT9914A is pin for pin compatible with Texas Instruments' TMS9914A with enhanced capabilities (i.e IEEE488.2).
