Technical Description The SeaLINK+16.VC utilizes sixteen USB UARTs. These chips feature programmable baud rate, data format, 128 byte Dual Port TX Buffer, and 384 byte Dual Port RX Buffer. The RS-232 transceivers support data rates up to 115.2K bps and the RS-485 transceivers support data rates up to 921.6K bps.
Optional RJ45 to DB9 RS-232 Adapter Preconfigured for use with Sealevel 2161 and 2167 serial devices, the RJ45 to DB9 modular adapter (item# RJ9P-232) converts the RJ45 RS-232 pin out to a DB9 male RS-232 serial port. Standard CAT5 patch cables can be used to extend the serial port up to 50 feet away from the RJ45 port. The pin out for the RJ9P-232 is shown below.
Electrical Characteristics Features Supports front or rear rack mounting or desktop use Provides 16 RJ45 serial ports with status LEDs Allows RS-232 or RS-485 pin out selection on port-by-port basis Includes two fully-rated (500mA) USB 1.

Appendix C – Electrical Interface RS-232 Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard.
Appendix D - Asynchronous Communications Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends. Asynchronous communications is the standard means of serial data communication for PC compatibles and PS/2 computers.
