I'm not sure what level you mean. The board uses IEEE-1284 protocol
to handshake bytes across the parallel port. The devices have a bunch
of registers that can be read or written. The encoder counters report
position as 24-bit signed numbers to the CPU. The PPMC servo card
set had a 16-bit DAC that receives signed 16-bit numbers that are
translated into +/- 10 V signals to the servo amps. The DIO card has
registers to sense the linit, etc. switches, and a register to control
the solid state relays. There is no 'language', so to speak. And, there's
no processor in these boards. That makes them quite fast.

The pages describing these products all have links to the Pico Systems
price list.

Replaces what? The PPMC is for use in servo systems, and is extendable
in increments, as the encoder counter, DAC and DIO are separate cards
that plug into a motherboard.

The Universal Stepper Controller is for stepper systems, and supports 4
axes per board. There is a provision for daisy-chaining more than one
unit on the same parallel port.
