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installed or withdrawn from the pack individually,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.

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.
