16-Axis MACRO CPU Hardware Reference Manual
Introduction 3
Configuration
The purchase of the 3U 16-Axis MACRO CPU board provides a 3U-format (100mm x 160mm) board
with a DSP processor, MACRO ring circuitry, and a backplane connector through which other 3U-format
boards can be connected by means of a UBUS passive-backplane board.
The 3U 16-Axis MACRO CPU can be purchased in two physical configurations, distinguished by part
number prefix:
• 300
-603719-10x provides the 16-Axis MACRO CPU board without a front plate. This configuration
is recommended for stack assemblies.
• 3A0
-603719-10x provides the 16-Axis MACRO CPU board with a front plate. This configuration is
recommended for UMAC rack assemblies. The top and bottom plates are provided with the Acc-Px
rack.
There are a few options available for the 16-Axis MACRO CPU board.
One of the Options A or C must be present on a 16-Axis MACRO CPU board to provide the actual
MACRO ring interface circuitry; both may be present:
Option A provides an SC-style fiber-optic transceiver to connect into the MACRO ring. Its main
component is the U73 transceiver.
Option C provides RJ-45 electrical input and output connectors for the MACRO ring. Its main
components are J14 and J17.
Option 10 permits a specified revision of the MACRO Station firmware to be installed in the flash
memory in the card. Without this option, the latest released revision is installed. A label on the flash
memory IC indicates the firmware revision installed at the factory (but not necessarily which revision is
presently installed in the IC). The presently installed revision can be ascertained by using the
MSVER{node #} command.
