Product Details

The Sealevel POS+4.PCI is a four channel PCI Bus serial I/O adapter supporting data rates up to 921.6K bps in the RS-485 mode and 460.8K in the RS-232 mode. This adapter is equipped with industry standard RJ-45 connectors to ease in cabling.

The RS-232 compatibility allows for connection to devices utilizing the RS-232 electrical interface, such as modems, data-entry terminals, and plotters.

RS-485 is optimized for ‘Multi-Drop’ or ‘Party-line’ operations selecting data from multiple peripherals (as many as 31 devices can be connected on an RS-485 bus).

In both RS-232 and RS-485 modes, the card works seamlessly with the standard operating system serial driver. In RS-485 mode, our special auto-enable feature allows the RS-485 ports to be viewed by the operating system as a COM: port. This allows the standard COM: driver to be utilized for RS-485 communications. Our on-board hardware automatically handles the RS-485 driver enable.

The POS+4.PCI provides the integrator with either fused +5 or +12 power for use in Point of Sale applications such as cash drawers and attention lamps. This power is selectable on a port by port basis allowing for fully customizable integrations.
