No more opening up the enclosure while digging through manuals and toolboxes. The serial ports on the new SeaLink USB serial adapters are software configurable for RS-232, RS-422, and RS-485 (two-wire and four-wire modes supported). There are no jumpers or dipswitches to set, eliminating the need to open the enclosure. Simply install the SeaCOM driver and connect the SeaLink adapter to a USB port on the computer. All configuration settings are intuitively handled via the driver interface, saving considerable field setup time. Additionally, the configuration settings are maintained locally in the SeaLink adapter enabling the host computer to be repaired or upgraded without having to reconfigure the serial ports.
This also allows the SeaLink adapters to be configured at one computer and deployed to other computers. Install the driver and plug the SeaLink adapter in and the electrical interface settings are maintained. In addition to Sealevel, two other vendors offer software configurable USB serial adapters. One vendor’s model maintains the settings on the computer, which requires the serial ports to be reconfigured if the host computer changes or if the device is moved to another computer. The other vendor’s model maintains the settings locally, but the device must be manually polled to retrieve the electrical interface settings. Sealevel’s software configurable USB serial adapters are easier to configure and use– the settings are stored locally in the device and the SeaCOM driver automatically retrieves the settings each time a port is opened. The new SeaLink software configurable USB serial adapters are a significant industry improvement, the company says.
