Option 1: Communications Interfaces
The Compact UMAC Turbo CPU board comes standard only with an RS-232/422 serial interface. The
Option 1 family provides faster interfaces for high-speed communications – Universal Serial Bus (USB),
Ethernet, or the link to the CPCI bus through a bridge daughter board.

Current Revision Communication Options (rev 103 and above)
Option 1: 100 Mbit/sec UDP/IP, TCP/IP Ethernet Communications Interface.

Option 1A: 480 Mbit/sec USB 2.0 Communications Interface (USB 1.1 compatible)
Option 1B: Solder-side stack connectors to CPCI-bridge daughter board. This option should be ordered
only when the bridge board is to be installed on the left side of the CPU board, so the CPU board is in the
leftmost slot of the Compact UBUS backplane, and the bridge board is in the rightmost slot of the
Compact PCI bus backplane.

Legacy Revision Communication Options (rev 102 and below)
Option 1: On-board 10-Base-T TCP/IP Ethernet interface. The key added components are U67 and U32.
Option 1A: On-board 12 Mbit/sec USB interface. The key added component is U67.
Option 1B: Solder-side stack connectors to CPCI-bridge daughter board. This option should be
ordered only when the bridge board is to be installed on the left side of the CPU board, so the CPU
board is in the leftmost slot of the Compact UBUS backplane, and the bridge board is in the rightmost

slot of the Compact PCI bus backplane.
Option 2: Dual-Ported RAM
With either the Option 1 Ethernet interface, or the Option 1A USB interface, communications throughput
can be increased through the use of dual-ported RAM, which provides a bank of memory that can be
directly accessed by both the Compact UMAC Turbo CPU and the communications microcontroller.
