PCIe MiniCard provides 4 opto-isolated serial ports.
September 9, 2013 -
Measuring 30 x 51 mm, Model DS-MPE-SER4OPT is available preconfigured for 4 RS-232 ports, 4 RS-485 ports, or combination of 2 RS-232 and 2 RS-485 ports. Each port offers 16C550 compatibility and ultra-deep 256 byte TX/RX FIFOs. Maximum data rates are 1 Mbps in RS-232 mode and 10 Mbps in RS-485 mode. Operating from -40 to +85°C, board features ±500 V ESD protection on all ports. Programmable slew rate minimizes ringing on long or un-terminated cables.

Low Cost, Rugged 4-Port Opto-Isolated Serial PCIe MiniCard
Ideal for add-on Serial Ports in Embedded Applications in Harsh Environments
Mountain View, California — Diamond Systems, a leading global supplier of compact, rugged, embedded computing solutions for real-world applications in a broad range of markets, today introduced a rugged, low cost 4-port multiprotocol opto-isolated serial port module in the popular PCIe MiniCard form factor measuring 30 x 51mm.
The DS-MPE-SER4OPT offers 4 RS-232/RS-485 opto-isolated serial ports in a PCIe MiniCard form factor. Each port offers 16C550 compatibility and ultra-deep 256-byte TX/RX FIFOs. Maximum data rates are 1Mbps in RS-232 mode and 10Mbps in RS-485 mode. The board is available preconfigured for 4 RS-232 ports, 4 RS-485 ports, or a combination of 2 RS-232 and 2 RS-485 ports. I/O signals are provided on two miniature latching connectors, with 2 ports per connector.
Each pair of serial ports on the DS-MPE-SER4OPT offers up to 500V isolation from the system ground. Optoisolation increases reliability in applications with long cable runs, where a difference in ground potential can cause significant ground loop currents, damaging non-isolated boards and equipment. Isolation on this miniature board is achieved through a combination of highly integrated isolated power + data components, careful component placement and layout, and a safety-enhancing insulation film on the bottom side, which prevents accidental contact with components on the carrier board.
Extended temperature capability of -40°C to +85°C enables the board to operate in environments with extreme temperature swings, such as vehicles or outdoor installations. In addition, the board may be custom-configured with 0-ohm resistors in place of jumper blocks for increased ruggedness in high-vibration environments.
The DS-MPE-SER4OPT’s key features and functions are tabulated below.
