4 And 8-Port PCIe/104 Serial Port Modules Offer Opto-Isolation

Diamond Systems’ Emerald-MM-8EL-XT family of high performance PCIe/104 OneBank serial I/O modules offer 4 or 8 serial ports with software-controlled configuration and optional opto-isolation. The serial ports are based on a high speed PCIe octal UART with 256-byte TX/RX FIFOs and auto RS-485 transmit control. Each serial port can be independently configured for RS-232, RS-422 or RS-485 protocols, along with programmable 120 Ω line termination. Each port features +/-15 KV ESD protection and is independently isolated with an isolated power + signal chip, plus additional isolators for control signals. The board features intelligent power management that limits inrush current on power-up and enables power-down of unused serial ports. With its full industrial temperature range of -40°C to +85°C and high resistance to shock and vibration, the modules fit a variety of rugged and on-vehicle embedded serial I/O application needs. The opto-isolated models feature independent 2500 V isolation circuits for enhanced reliability in vehicle or long cable applications. The PCIe/104 serial module family is available immediately with single unit pricing starting at $675 for the Emerald-MM-8EL-XT model.
