What’s the Difference Between PCIe/104 and COM Express?
At Sealevel, we love designing with both PCIe/104 and COM Express for embedded systems. Both options have great benefits. They: When deciding which design path…
Is the 7203e PCIe serial interface dip switch or software configurable to change the RS-485 termination from a 120 Ohm resistor to an AC termination?
Sealevel’s 7203e does have onboard dip switches that would allow you to turn off the 102 Ohm resistor; the 120 Ohm resistor can be changed through dip…
COM Module Technology: PCIe/104 & COM Express
In embedded computer systems, COM technology enables the use of an off-the-shelf computer module with a custom, application-specific carrier board, or boards, to fulfill the…
PCIe Mini Card Synchronous Serial Interface
Connecting modern computer equipment to proprietary, often old, infrastructure is a common requirement in military applications. For example, Sealevel was contacted by the manufacturer of a rugged, military computer server to design an interface to radio modems installed in aircraft.
Serial I/O – Just as Useful Today
With many things, newer doesn’t necessarily mean better. Automobiles are a good example. Porsche remains the measuring stick in sports cars, yet the design of…
New PCI Express with Two Optically Isolated Serial Ports
Sealevel’s 7203e PCI Express serial interface provides two optically isolated serial ports, each individually configurable for RS-232, RS-422, or RS-485. Each serial port utilizes a…
