Front UART Control

The MVME2500 utilizes one of the two UART functions provided in the male micro-mini
DB-9 front panel. A male-to-male micro-mini DB-9 to DB9 adapter cable is available under
SMART EC Part Number SERIAL-MINI-D2 and is approximately 12 inches in length.
Only 115200 bps and 9600 bps are supported. The default baud rate on the front panel
serial is 9600 kbps.
4.8

Rear UART Control

The MVME2500 utilizes the Exar ST16C554 quad UART (QUART) to provide four
additional ports to the RTM. These devices feature 16 bytes of transmit and receive first-in
first-out (FIFO) with selectable receive FIFO trigger levels and data rates of up to 1.5 Mbps.
Each UART has a set of registers that provide the user with operating status and control.
The QUART are 8-bit devices connected to the processor through the local bus controller
using LBC chipset CS1, CS2, CS3 and CS4.
These four serial interfaces are routed to P2 I/O for RTM accessibility. There are a total of
five serial ports available on the MVME2500.
4.9

PMC/XMC Sites

The MVME2500 hosts only one PMC/XMC site and accepts either a PMC or an XMC add-
on card. Only an XMC or a PMC may be populated at any given time as both occupy the
same physical space on the PCB. Combination PMC/XM cards are not supported by the
MVME2500. The site provides a rear PMC I/O.
The PMC site is fully compliant with the following:
1. VITA 39 –PCI-X for PMC
2. VITA 35-2000 for PMC P4 to VME P2 Connection
3. PCI Rev 2.2 for PCI Local Bus Specification.
4. PCI-X PT 2.0 for PCI-X Protocol Addendum to the PCI Local Bus Specs.
5. IEEE Standard P1386-2001 for Standard for Common Mezzanine Card Family
6. IEEE Standard P1386.1-2001 for Standard Physical and Environmental Layer for PCI
Mezzanine Card.
7. VITA 42 for XMC
8. VITA 42.3, PCIe for XMC
