The Abaco Systems IP-Altera / IP-Altera-RO is a single-wide IndustryPack module that delivers 28 programmable digital I/O lines for custom protocol implementation and non-standard signal interfacing. Built around an Altera 10K40-3 FPGA, this module combines 20 differential I/O lines with 8 TTL I/O lines, each with independently programmable direction. The design integrates LineSafe ESD protection on TTL channels and socketed termination resistors on differential lines, making it ideal for aerospace and satellite test applications requiring flexible digital I/O control.
