Page 10: Handling And Installation
1 • Handling and Installation 1.1 Handling Precautions CAUTION Handle the board by the edges or front panel only. Electronic assemblies use devices that are sensitive to static discharge. Some of the components assembled on GE products may be sensitive to electrostatic discharge and damage may occur on boards that are subjected to a high energy electrostatic field. Observe anti‐static procedures when handling these boards. All products should be in an anti‐static plastic bag or conductive foam for storage or shipment. Work at an approved anti‐static workstation when unpacking boards. When the board is placed on a bench for configuring, etc., it is suggested that conductive material be inserted under the board to provide a conductive shunt.Unused boards should be stored in the same protective boxes in which they were shipped. 1.2 Unpacking Procedures Any precautions found in the shipping container should be observed. All items should be carefully unpacked and thoroughly inspected for damage that might have occurred during shipment. The board(s) should be checked for broken components, damaged printed circuit board(s), heat damage and other visible contamination. All claims arising from shipping damage should be filed with the carrier and a complete report sent to GE Technical Support. Remove the PMC423 from the shipping box and anti‐static packaging. Verify that it is not damaged and that all items are present by referring to the packing list. 10 PMC423 Port Serial, Front/Rear I/O Hardware Reference Manual... -
Page 11: Installation
1.3 Installation The PMC module is now ready for installation. Installation is done generically as with the commercial versions of the card. Follow any specific procedures recommended by the manufacturer of the chassis used. Perform the following steps: 1. Turn all system power OFF. 2. Remove the host board from the chassis (if currently installed). 3. Locate the PMC connectors on the host board. 4. Carefully plug the PMC module into the mating connectors on the host’s printed circuit board. 5. Make sure the PMC module is seated properly into the common mezzanine card (CMC) connectors on the host. 6. Use screws to fasten PMC to the host CMC. 7. Remove the four screws from the bottom of the stand‐offs of the PMC. 8. Line‐up the J1 and J2 connectors on the host CMC to the J1 and J2 connectors on the PMC. 9. Ensure all connectors are properly aligned before pushing the connectors together. 10. Use the four screws to connect the PMC stand‐offs to the host CMC. 11. The chassis may now be powered up.

Page 14: I/O Signal Pinouts
1.5 I/O Signal Pinouts Each serial port has two control signals: • TX ‐ Transmitted Data • RX ‐ Received Data To support differential signaling standards (e.g., RS422), each signal has a positive and negative line. When using a single ended standard (e.g., RS232), use the negative version. All I/O signals are available both at the front panel connector and on the J4 “backplane” connector. The following table details all connections. Table 1-1 I/O Signal Pinouts PMC423 Port Signal Front Panel Pin J4 Pin Port Signal Positive Negative Positive Negative NOTE Ground is available on the front panel connector on pins 9, 27, 43 and 61. 14 PMC423 Port Serial, Front/Rear I/O Hardware Reference Manual... -

Page 17: Theory Of Operation
2 • Theory of Operation This chapter provides information for local device connections, the bridge to the host PCI, and the general systemʹs function. The design of the PMC423 is illustrated in the block diagram that follows. 2.1 PMC423 Block Diagram Figure 2-1 PMC423 Block Diagram Host PCI PCI/PCI Bridge 8 Port Serial 8 Port Serial Signal Signal Signal Signal Conditioning Conditioning Conditioning Conditioning Port Port The PMC423 can operate with the 32‐bit 33/66MHz PCI bus, +3.3V or +5V PCI signaling. This allows for the maximum flexibility for the different PCI bus speeds, and signaling. The signaling level for the serial communication (RS232, RS422, etc.) are configured via the software. The card generates the necessary ... - Page 18 The PMC423 is a flexible solution for integrating multiple serial I/O channels onto a Single Board Computer (SBC). Efficiently packaging sixteen channels onto a single PMC makes effective use of the few PMC locations available. Routing I/O to the rear (via the ‘J4’ connector to the host card) enhances flexibility in developing economical, and non‐intrusive cabling solutions. Each serial port is implemented with an independent UART (Asynchronous Receiver and Transmitter) with a separate programmable baud rate. Accessing the UART controllers via PCI, integrates more effectively to modern SBC implementations than proprietary or legacy devices. Traditional UART controllers are limited to 8‐bit access, incurring all bus protocol overhead for every character transferred (and control operations). The Octal UART utilized on the PMC423 supports 32‐bit transfers, allowing four characters to be transferred in a single bus operation. Reducing programmed I/O operations is critical to achieving good performance in PCI systems. While the extended transfer options offer an opportunity to maximize performance, in many cases, the first (and sometimes only) criteria are software development and integration. The 16C550 register set definition is in common usage for serial I/O devices in all environments. Maintaining compatibility with this de facto standard can markedly reduce the time required to integrate the PMC423 into existing software environments. Having the software integration based upon earlier drives reduces the risk of unexpected (and undesirable) changes in application interfaces, which can be critical when creating an evolutionary improvement of existing systems. 18 PMC423 Port Serial, Front/Rear I/O Hardware Reference Manual...
