8010G – RoHS compliant, 8 Port RS232 Asynchronous Communication PMC Adapter The 8-Port Asynchronous Communication PMC adapter provides eight industry standard 16550-based UARTs using RS232 signaling levels. • • • • •
•
True 16550 UARTs operate at up to 115K baud Front and rear access to I/O 32-bits / 33 MHz PCI bus (PLX 9030) 3.3V or 5V PCI Signaling Drop-in replacement for ACT P/N 8010 (vendor and device IDs preserved, register compatible) RoHS-compliant, lead free
Each port provides the full set of data and modem control lines configured for DTE (i.e., computer side) operation: • • • •
RTS (Request to Send) CTS (Clear to Send) TXD (Transmit Data) RXD (Receive Data)
• • • •
DCD (Data Carrier Detect) DTR (Data Terminal Ready) DSR (Data Set Ready) RI (Ring Indicator)
The UARTs operate at standard baud rates from 300 baud to 115K-baud. Other odd-baud rates are possible and are available on special order. The bridge between the 16550 register set and the PCI bus is a PLX 9030 chip this is a slave only device so all access from the host processor is done through programmed I/O to the PCI bus I/O space, as is customarily done for Async communication software. Once the registers are mapped into host I/O space, standard Async communication drivers may be used to access the ports. The eight interrupt requests from each UART are routed to one of the four INTx lines on the PCI bus. This design avoids interrupt routing switches by incorporating a programmable element which can be set up from the host processor, allowing any UART to be routed to any INTx request line. The default after reset is all UART interrupt requests are routed to the INTA line. The 16550 register set is accessed from the host processor using Programmed-I/O. “C” source code is provided with the board to illustrate how to set up the PCI bus bridge in order to access the UART registers. Once the registers are mapped into host I/O space, standard async communication drivers may be used to access the ports. For rear I/O, a paddle card available from ACT converts the P2 ‘a’ and ‘c’ rows back into the 68-pinSCSI style connector. This permits use of the eight 9- pin D-Sub transition panel for rear-exit from the card cage. A transition panel available from ACT converts the 68-pin SCSI style connector into eight 9-pin male DSubminiature connectors, which are pinned-out according to the Personal Computer standard. The transition panel may also be mounted at any convenient point in a user’s system. Since the PN4 signals and J1 signals are in parallel and are not buffered, it is not possible to use both connections simultaneously.
The ACT 8010G PMC is a ROHS and Industrial temperature upgrade for the ACT P/N 8010 and is a drop-in replacement. While the 8010 used a PLX 9052 bridge chip and is useable on 5V PCI signaling carrier cards only, the 8010G PMC uses a PLX 9030 bridge chip allowing use with 3V or 5V PCI signaling carrier cards.
