The SeaLINK® 2167 16-port USB to serial adapter offers an easy way to connect multiple RS-232 or RS-485 devices via a single USB port. With the unique VersaCom multi-interface connector design included on the 2167, both RS-232 and two-wire RS-485 signals are always present and active on the RJ45 serial connectors. Simply select the appropriate pin out for RS-232 or two-wire RS-485 on each individual port. There is never a need to open the enclosure to set internal jumpers, switches, or shunts, so field installation and service is easy. Tx and Rx activity LEDs are also included to display status and assist in troubleshooting.

Sealevel’s SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. After installing the software, each serial port appears as a standard COM port to the host system enabling compatibility with legacy software. The 1U rackmount-compatible system uses a state machine architecture that greatly reduces the host computer’s overhead when communicating over multiple ports simultaneously. Data rates up to 921.6K bps are supported. Two convenient USB 1.1 downstream connections are also provided to allow daisy-chaining SeaLINK devices or interfacing standard USB peripherals.

To further simplify connecting to VersaCom RJ45 connectors, Sealevel offers a number of accessories including RJ45 modular adapters. With these helpful adapters, you can easily connect to serial ports on virtually any computer, PLC, or peripheral regardless of the device’s serial connector type or gender.
