The cards offer serial compatibility with the PCI Express bus for use by system integrators and manufacturers in the design of industrial and commercial systems. Each COM port is capable of supporting data rates up to 3Mbps and implements full modem control signals in RS-232 mode to ensure compatibility with a broad variety of serial devices. The card features a x1 lane PCI Express connector which can be used in any available x1, x2, x4, x8, x12, or x16 PCI Express expansion slot. The card is 6.6 inches in length and 2.2 inches seated height and complies with the MD2 Low Profile Form Factor specification. Low profile PCI Express allows the design of small footprint, low profile systems while still offering expandability and upgradeability to the end user. A regular profile mounting bracket is installed for use in standard size computers, while an optional low profile bracket is available for smaller systems which require the use of low profile PCI Express cards. Typical serial peripherals can connect directly to the industry standard DB9M connectors on an optional breakout cable (see Ordering Guide). For DB9 pin-compatibility with legacy RS-485 systems that use our LPCI and PCI- COM485-8 cards and breakout cables, order the “NC” card model and breakout cable CAB-PCIe-485-8 (see DB9M RS-485 Pin Table). SPECIAL ORDER Please contact ACCES with your precise requirement. Other examples of special orders would be conformal coating, custom software, RJ45 connectivity, longer breakout cables, etc., we will work with you to provide exactly what is required. SOFTWARE A complete driver support package is provided including an easy-to-use Windows terminal program for testing your COM ports. This simplifies the verification of proper COM port operation. The card installs as standard COM ports in all operating systems including DOS, Linux (including Mac OS X) and 32- and 64-bit Windows. 10623 Roselle Street, San Diego, CA 92121 • (858) 550-9559 • Fax (858) 550-7322 • contactus@accesio.com • www.accesio.com th June 12 , 2010 BLOCK DIAGRAM ORDERING GUIDE SPECIFICATIONS PCIe-COM-8SM Eight-port RS-232/422/485 card w/cable PCIe-COM-4SM Four-port RS-232/422/485 card w/cable I/O connection: VHDCI 68 pin SCSI connector PCIe-COM485-8 Eight-port 2-wire RS-485 card w/cable Serial ports: 8 (or 4) RS-232/422/485 PCIe-COM485-4 Four-port 2-wire RS-485 card w/cable Serial data rates: RS-232 460.8k (921.6k avail) PCIe-COM422-8 Eight-port RS-422 (4-wire 485) card w/cbl RS-422/485 3Mbps PCIe-COM422-4 Four-port RS-422 (4-wire 485) card w/cbl UART: Octal type 16C950 with 128-byte transmit & receive FIFO, 16C550 To order a card without the cable, add “NC” (PCIe-COM422-4NC) compliant ESD Protection: ±15kV on all signal pins Character length: 5, 6, 7, or 8 bits Model Options Parity: Even, Odd, None, Space, Mark • -T Ext. temp. operation (-40° to +85°C) Stop interval: 1, 1.5, or 2 bits • -F Fast version (RS-232 up to 921.6kbps) Flow Control: RTS/CTS and/or DSR/DTR, Xon/Xoff • -RoHS RoHS compliant version Cable: 3’ shielded breakout cable terminated • -W Remote wake-up enable with 8 (or 4) male DB9-pin connectors • -L Low profile bracket installed Environmental Accessories BRKT-551-SCB Connector stabilizer bracket (for use with Operating temp. standard height PCIe bracket only) Commercial: 0°C to +70°C ADAP9 DB9F to 9 screw terminals adaptor Industrial: -40°C to +85°C ADAP9-2 Dual DB9F to 18 screw terminals adaptor CAB-PCIe-485-8 3’ DB9M breakout cable pin-compatible Storage temp.: -65°C to +150°C with legacy PCI- and LPCI-COM485-8 Humidity: 5% to 95%, non-condensing Power required: +3.3VDC @ 0.9W (typical) 2-Wire RS-485 2-Wire RS-485 DB9M PIN Size: 6.6 inches long x 2.20 inches high Standard Cable Legacy Cable (167.64 mm long x 55.8 mm high) 1 - TX/RX- 2 - - 3 TX/RX+ - 4 TX/RX- - 5 GND GND 6 - - 7 - - 8 - - 9 - TX/RX+ DB9M RS-485 PIN TABLE 10623 Roselle Street, San Diego, CA 92121 • (858) 550-9559 • Fax (858) 550-7322 • contactus@accesio.com • www.accesio.com th June 12 2010
