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installed or withdrawn from the pack individually,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.
