IOtech 488/80A Digital I/O Converter
The Digital 488/80A is a digital input and output interface to the IEEE 488 bus that enables an IEEE 488 controller to program 80 bits of TTL level signals as either inputs or outputs. It includes 6 handshake/control lines for each 40-bit channel and two addressing modes. The unit is fully programmable including the power-up configuration, which is stored in non-volatile RAM. The internal data buffer in the Digital488/80A can store up to 2,000 40-byte words.
This unit has 80 TTL level digital I/O lines that are divided into two 40-bit channels. Each channel is divided into five 8-bit ports. Six high level ASCII commands configure the ports to be all inputs, all outputs or combinations in between. Thus, a configuration can range from 80 input lines to 80- output lines or combinations in between in multiples of 8 bits.
