The Moxa POS-104UL-T is a 4-port RS-232 universal PCI interface card, specifically developed for use in POS systems, cash dispensers, and industrial automation applications. The card features a serial power supply, enabling it to power external devices through the serial ports in addition to data transmission. It is designed for use in compact industrial PCs and features a low-profile form factor, which is advantageous in systems with limited space. The T-model variant is designed for demanding industrial environments and supports an extended operating temperature range.

Applications

The POS-104UL-T is primarily intended for applications in the point-of-sale sector, cash dispensers, and industrial automation. It is suitable for connecting serial peripheral devices such as cash registers, printers, scanners, barcode scanners, terminals, and other devices communicating via RS-232 interfaces. The integrated power supply allows external devices to be powered through the serial ports, reducing the need for additional power supplies.

Functions and Features in Detail

The card provides four independent RS-232 interfaces, connected via a DB44 socket. An included adapter cable enables conversion to four separate DB9 connectors, simplifying connection to standard peripheral devices. Each port can be powered with either 5 V or 12 V at a current of 1 A. Data transfer rates can be set up to 921.6 kbps, sufficient for many industrial applications. The card supports various data formats, including 5, 6, 7, or 8 data bits, stop bits of 1, 1.5, or 2, and parity types such as None, Even, Odd, Space, and Mark. Flow control methods such as RTS/CTS and XON/XOFF are also available. The integrated communication controller is 16C550C-compatible and features a 128-byte FIFO buffer, enhancing data transmission efficiency.

Technology Explained Simply

The POS-104UL-T operates as a universal PCI card, compatible with both 3.3 V and 5 V PCI and PCI-X buses. This ensures broad usability in various industrial PCs. The serial power supply allows external devices to be powered directly through the RS-232 ports, reducing the number of required power supplies. The card is designed for operation in environments with enhanced electromagnetic compatibility (EMC) and complies with standards EN 61000-6-2/-6-4 and FCC Part 15B Class B. Additionally, it is protected against electrostatic discharge (ESD) up to 4 kV (contact) and 8 kV (air), as well as electrical disturbances such as EFT (2 kV power, 1 kV signal) and Surge (2 kV power). Environmental certifications RoHS, CRoHS, and WEEE ensure environmentally compatible manufacturing and disposal.

Compatibility and Accessories

The card is compatible with a wide range of operating systems, including Windows (from DOS to Windows 10, including Embedded CE/XP), Linux (kernel 2.4.x to 5.x), and UNIX (Solaris 10, UnixWare 7, SCO OpenServer 5/6). Driver support is comprehensive, enabling easy integration into existing systems. The maximum number of installable cards per PC is eight, allowing for high scalability. The included adapter cable (M44 to 4x DB9-M, 50 cm) simplifies connection to standard peripheral devices.

Installation and Mounting

Installation is performed via the PCI bus of an industrial PC. The low-profile form factor requires no additional mounting adapters and fits into standard PC enclosures with limited space. The included quick installation guide supports installation and configuration. The card is delivered with an adapter cable, a quick installation guide, a substance declaration, and a warranty card.

Operational Advantages

The POS-104UL-T offers high reliability with an MTBF of 2,124,022 hours (according to Telcordia TR/SR) and is designed for use in demanding environments. The T-model variant allows operation at temperatures from -40 to 85 °C, making it suitable for industrial applications in extreme environments. The integrated power supply reduces the number of external power supplies and simplifies system architecture. Universal compatibility with various operating systems and comprehensive driver support facilitate integration into existing systems.

Scope of Delivery

The scope of delivery includes the POS-104UL-T card, an M44-to-4x-DB9-M adapter cable (50 cm), a quick installation guide, a substance declaration, and a warranty card. The card is designed for use in compact industrial PCs and provides a robust, reliable, and flexible solution for serial communication in industrial applications.

Certifications and Environmental Standards

The card complies with EMC standards EN 61000-6-2/-6-4 and FCC Part 15B Class B. It is protected against ESD (4 kV contact, 8 kV air), RS (10 V/m), EFT (2 kV power, 1 kV signal), and Surge (2 kV power). Environmental certifications RoHS, CRoHS, and WEEE ensure environmentally compatible manufacturing and disposal.
