The Exsys EX-41016-2 is a PCI serial card with 16 RS-232 ports, designed for use in industrial and server-based systems where a high number of serial device connections are required. The card supports both the PCI and PCI-X bus standards, making it compatible with a wide range of computer systems. It is based on the SystemBase chipset 16C1054PCI and features an integrated 16C1050 FIFO buffer with 256 bytes, enabling efficient and reliable data transfer. The maximum baud rate is 921.6 kBaud/s, which is sufficient for many industrial applications. The card is Plug-and-Play capable and supports Low-Profile enclosures, allowing it to be used in compact or rack-mounted systems with a maximum height of 8 cm. An integrated ESD protection (±15 kV according to IEC1000-4-2) protects sensitive components from static discharges. The operating temperature ranges from 0 to 55 °C, suitable for use in controlled indoor environments. The storage temperature is -20 to 85 °C. Power consumption is 3.3 V / 900 mA. The card is designed for operating systems such as Windows NT 4.0 to 10, Server 20xx, Linux, and SCO-Unix. It is certified according to CE, FCC, RoHS, and WEEE (DE97424562). Included accessories consist of 2 Octopus cables, 32 nuts, a Low-Profile bracket, a driver CD, and a manual, simplifying installation and configuration.

Applications
The Exsys EX-41016-2 is suitable for applications requiring multiple serial devices such as industrial sensors, printers, modems, POS terminals, or other legacy devices to be connected to a computer. It is commonly used in server environments, industrial controls, data acquisition systems, and automation technology, where stable and reliable serial communication is required. The support for Low-Profile enclosures makes it particularly suitable for rack systems and compact servers.

Features and Specifications in Detail
The card features 16 independent RS-232 interfaces, each implemented via a 9-pin DB9 connector. Each port supports data bits from 5 to 8, stop bits of 1, 1.5, or 2, and parity types including none, even, odd, space, and mark. Flow control options include RTS/CTS and XON/XOFF, enabling controlled data transfer. Signals TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND are available on each port. Power supply on the bus is provided at 5 V and 3.3 V, with power supply at pin 9 configurable via jumper. The card is designed for operation in a temperature range of 0 to 55 °C, making it suitable for use in controlled indoor environments.

Technology Explained Simply
The SystemBase 16C1054PCI chipset controls the serial ports and enables high data transfer rates. The integrated FIFO buffer with 256 bytes per port acts as a buffer for transmitted data, reducing CPU load and making data transfer more efficient. The maximum baud rate of 921.6 kBaud/s is sufficient for many industrial applications, as this speed is typically adequate for transferring data from sensors, terminals, or other serial devices. The ESD protection safeguards the card against static discharges that may occur during installation or when connecting devices. Plug-and-Play capability simplifies installation, as the card is automatically detected and configured by most operating systems.

Compatibility and Accessories
The card is compatible with Windows NT 4.0, 9x, 2000, XP, Vista, 7, 8.x, 10, Server 20xx, Linux, and SCO-Unix. The included Octopus cables simplify connecting multiple devices, while the 32 nuts and Low-Profile bracket support installation in various enclosures. The driver CD and manual assist with installation and configuration. The card is designed for PCI and PCI-X bus standards and supports both 5 V and 3.3 V operating voltages on the bus.

Installation and Mounting
Installation involves inserting the card into a free PCI or PCI-X slot on the computer. The card is Plug-and-Play capable, so it is automatically recognized by most operating systems. The included Octopus cables and nuts simplify wiring and mounting. The Low-Profile bracket allows use in enclosures with a maximum height of 8 cm. The power supply at pin 9 can be configured via a jumper to ensure compatibility with various systems. The driver CD and manual support card configuration.

Operational Advantages
The Exsys EX-41016-2 provides a high number of serial ports in a single module, reducing the number of required expansion cards and lowering system complexity. Support for Low-Profile enclosures and Plug-and-Play capability simplifies installation in rack systems. The integrated ESD protection increases the card’s reliability, especially in environments with high electrostatic loads. The high baud rate and FIFO buffer ensure efficient data transfer, reducing CPU load. Compatibility with various operating systems makes the card flexible for use in different environments.
