CHAPTER 1 OVERVIEW This section contains diagrams of the interrupt and memory decoding capabilities used in the Plug and Play setup of the ACR8020 motherboard. NOTE: It is important to read the README file located on the Acroloop CD before attempting any PC installation of the ACR8020 board.
ACR8020 MOTHERBOARD PLUG AND PLAY CAPABILITY Dual Port Memory Address Select The ACR8020 can receive and transmit data through it’s Dual Port Memory accessible on the PCI bus. The dual port memory address range is automatically configured in Windows via the ACR8020’s PCI Plug and Play interface.
CHAPTER 2 OVERVIEW This section contains diagrams of the jumpers and switches on the ACR8020 motherboard. Encoder pull-up jumpers must be set correctly based on the types of encoders being used. Failure to set these jumpers correctly may cause damage to the encoders or to the receivers on the controller card.
Serial Communication Card Selection / User Switch (SW1) Serial communications via the COM1 and COM2 communication ports on the optional ACRCOMM module are performed with multiple cards using different ACR8020 card numbers. The following table shows how the switch positions 1 through 4 relate to the ACR8020 card number.

ACR8020 MOTHERBOARD HARDWARE WIRING This section contains diagrams of the connectors on the ACR8020 motherboard. Before optically-isolated digital inputs and outputs can be used, the card must be connected to an external +24V DC power supply. This connection is made at the PWR1 connector and is fused on-board at 4 amps to protect the controller card.
ACR8020 MOTHERBOARD HARDWARE WIRING Encoder Inputs (P1A, P1B, P1C) There are two 34 pin headers and one 20 pin header provided on the ACR8020 for encoder feedback. The two 34 pin header provide up to eight (8) axes of encoder feedback (Encoders 0 thru 7).

ACR8020 MOTHERBOARD HARDWARE WIRING Encoder Inputs (P1A, P1B, P1C), cont’d. P1C is designed to work in conjunction with a 20 pin ribbon cable terminated to two (2) standard 9-pin female D-sub type connectors. This 12 inch cable, AMCS P/N PWH015, is supplied with the Encoder 8/9 Option.
Page 31
When using a single-ended encoder (an encoder without the A-, B-, or Z- outputs), additional pull-ups and pull-down resistors must be added externally to the ACR8020 board in order for the ACR8020 to read the encoder signals. Warning: This is not a recommended mode of operation. Noise immunity is significantly reduced.
Analog Input/Output (P2) The analog input/output connections are made through a 37-pin D-style connector on the side of the ACR8020 motion controller. Refer to Figure 1 for connector location. Note: P2 is a standard 37-pin female D-plug. Pin definitions in parentheses are for stepper modules.
Digital Inputs / Outputs (P3 and P4) There are two 34 pin headers provided on the ACR8020 for digital I/O interface. The 34 pin headers are used for the 32 Digital Inputs and 32 Digital Outputs. Refer to Figure 1 for connector location.
The ACRCOMM Plug-In Module provides serial communication ports (2 serial, 1 parallel) capability for the ACR8020 motherboard. ACRCOMM external power input and User-SRAM battery back-up functions are not used with the ACR8020 motherboard. These circuits are not populated on the ACR8020 COMM Board.
(or any time) via the PCI bus communications port. The following tables show the configuration schemes for the ACR8020 board with the serial communication ACRCOMM module option. Refer to the User’s Guide manual, COM1/COM2 Stream Flags, Appendix B, for bit flag details.
