MACRO-CPU Hardware Reference

3U MACRO-CPU Board (3A0-602804-10x):

•80MHz DSP56303 CPU

•512k x 8 flash memory for user backup & firmware

•Latest released firmware version

•RS-232 serial interface for setup and debugging

•Stack connectors for servo and I/O accessory boards

•UBUS connector for backplane connection to servo and I/O accessory boards

•JTHW multiplexed I/O port with 26-pin IDC header

The 3U MACRO Station can be configured in either of two fundamental assemblies – “UMAC MACRO” and “MACRO Stack”:

•UMAC MACRO – In this configuration (once called "Pack") the 3U-format boards are put together to communicate through a backplane bus called the UBUS. All boards are installed in a Euro-card rack. In this configuration, all 3U-format boards or modules can be installed or withdrawn from the pack individually, providing ease of installation, debugging, and repair.

The photo at the upper right shows a UMAC rack with power supply and I/O boards that are connected through a backplane. This system allows for an easier integration of the 3U MACRO-CPU for larger (up to 8 axes) applications.

•MACRO Stack – In the Stack configuration the 3U-format boards are put together as a stack of piggyback boards, (right, below). This configuration is ideal for compact, cost-sensitive embedded applications.

4 Axis Stack Configuration

Note:

The Stack boards and related breakout boards can be installed in a Euro-card rack, creating a hybrid “stack/pack” configuration. This requires a special backplane configuration that makes removing stack boards difficult.

This hybrid configuration is now recommended for existing “legacy” systems only.
