• 32-bit parallel I/O RS422 up to 10 MHz
Packing Options
The DPIO can be set up to use different packing options. This is done by reloading a
“Packing PLD” on the DPIO. VMETRO provides a PLD Reprogramming Kit (part no.
PLD-KIT-DPIO) for this purpose. The kit contains everything that is needed: a PC
parallel port cable, JEDEC files for all packing options, and software.
