REELEX manufacturers many of their own boards, the “Counter Boards” can be found across almost all REELEX equipment. We have several different boards that perform similar functions.
W600: W-600 Counter Board
This board lives within the cardrack on “Generation One” equipment (z80 processor machines). The card can count up to 16 bits and has anti jitter capabilities. The board is responsible for converting the encoder quadrature pulses into binary for the machine’s software to use. The boards should increment and decrement between 0 - 719.The computer software will read this board at frequencies up to 1 khz,so it's imperative that every digit works properly.
All W600 boards can be easily converted into one of four different variations. Depending on your encoders pulse per revolution scaler you’ll need to modify the board to match your resolution.
W600 A: Remove J1 and remove IC 2, This will allow the board to work properly with 2400PPR encoder
W600 B: Install J1 and install IC 2, This will allow the board to work properly with 2400PPR encoder
W600 C: Remove J1 and remove IC 3, This will allow the board to work properly with 240PPR encoder
W600 D: Install J1 and install IC 3, This will allow the board to work properly with 240PPR encoder
This board lives inside the industrial PC chassis: It’s exclusive to the “Generation Two” platform. The board shares the same purpose of the W600 found on earlier Generation 1 equipment. It is responsible for converting the quadrature encoder pulses into a usable binary count from the software. The W602 also contains circuitry for handling a length counter for our software to read.
This board is almost identical to the W602. The only difference is the numbering format that's presented to the machine's software. This board lives exclusively inside the REELEX “Generation Two” D-1500. It’s responsible for reading the right side “spindle”(spindle 2) encoder. The length counter circuit is not used in this rendition.
The W603 is exclusive to all Generation 2 PC based machines. This machine's board is dual purpose, as it serves two rolls providing the software with time based interrupts and converting encoder pulses into a usable number for the computer (D-20XX boxing table).
