Product Description
The Sealevel Systems SeaLINK+485-DB9 serial interface adapter provides the PC with a single USB to RS-485
asynchronous serial port providing a versatile interface for common RS-485 needs. The SeaLINK+485
connects to a PC’s external USB port, so it does not require opening the computer case. Resources such as
IRQs and I/O addresses are also not utilized.
The SeaLINK® USB to RS-485 serial adapter utilizes Sealevel’s expertise in military-grade designs by
incorporating a ruggedized, overmolded enclosure design. This improves the reliability and durability in
industrial and mobile applications such as GPS navigation systems, barcode readers, signature input
devices, serial printers, scales, and similar applications.
The 2107 features programmable baud rate and data formats with 128-byte transmit and 256-byte receive
buffers. The USB serial adapter is compatible with all standard PC baud rates and supports high-speed
communication to 921.6K bps. The 2107 is powered by the USB port and status LEDs molded into the
enclosure indicate serial data activity and connection to the host.
Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Windows and
Linux operating systems. After installing the software, simply plug the 2107 into an available USB port and
the serial port is recognized as a standard COM port by the host system enabling compatibility with legacy
software.
The attached cable is 44 inches long and fully shielded to protect the 2107 from RF and EMI interference
that is common in mobile and industrial environments. Standard operating temperature range is -40° -
+75°C.
Compliant with RoHS and WEEE directives
High-speed UART with 128-byte Tx FIFO and
384-byte Rx FIFO
Data rates to 921.6K bps
All modem control signals implemented
Powered by USB connection
DB9M connector

Depending upon your application, you are likely to find one or more of the following items useful with the
2107. All items can be purchased from our website (www.sealevel.com) by calling our sales team at (864)
843-4343.
Terminal Block - DB9 Female to 5 Screw Terminals (RS-422/485) (Part# TB34)
The TB34 terminal block adapter offers a simple solution
for connecting RS-422 and RS-485 field wiring to a serial
port. The terminal block is compatible with 2-wire and 4-
wire RS-485 networks and matches the RS-422/485 pin-
out on Sealevel serial devices with DB9 male connectors.
A pair of thumbscrews secures the adapter to the serial
port and prevents accidental disconnection. The TB34 is
compact and allows multiple adapters to be used on
multi-port serial devices, such as Sealevel USB serial
adapters, Ethernet serial servers and other Sealevel serial
devices with two or more ports.
DB9F to DB25M (RS-485) Extension Cable (Part# CA177)
The CA177 is a standard AT-style RS-485 modem cable
with a DB9F connector on one end and a DB25M
connector on the other. This cable is 72 inches in length.
DB9F to DB9M Extension Cable (Part# CA127)
The CA127 allows users to extend a DB9 cable up to six
feet. The connectors are pinned one-to-one so the cable
is compatible with any device or cable that has DB9
connectors.
DB9 Female to 9 Screw Terminal (Part# TB05)
The TB05 terminal block breaks out a DB9 connector to
9 screw terminals to simplify field wiring of serial
connections. It is ideal for RS-422 and RS-485 networks,
yet it will work with any DB9 serial connection, including
RS-232. The TB05 includes holes for board or panel
mounting. The TB05 is designed to connect directly to
Sealevel DB9 serial cards or any cable with a DB9M
connector.

High Speed 4-Port USB 2.0 Hub with SeaLATCH USB Ports (Part# HUB4P)
The hub is USB 2.0 compliant, providing a full 480M bps
data rate to the host, and is backwards compatible with
USB 1.1 and 1.0 devices. The HUB4P includes a wall-
mount AC adapter that supplies a full 500mA to each
attached USB peripheral. The power supply outputs
5VDC @ 2.4A and has a locking DC connector to prevent
accidental removal of the power cable.
High Speed 7-Port USB 2.0 Hub (Part# Hub 7P)
The HUB7P is USB 2.0 compliant, providing a full 480M
bps data rate to the host, and is backwards compatible
with USB 1.1 and 1.0 devices. The powered hub includes
a wall-mount AC adapter that supplies a full 500mA to
each attached USB peripheral. The power supply outputs
5VDC @ 4A and has a locking DC connector to prevent
accidental removal of the power cable. The hub is
housed in a rugged plastic enclosure and status LEDs
indicate external power, connection to the host, and
fault conditions.
DB9F to RJ45 Modular Adapter (Item# RJ9S8)
The RJ9S8 is a DB9 female to RJ45 adapter. It can be
configured without tools and is an excellent choice for
using available infrastructure wiring.
DB9 Female to DB9 Male - Serial Surge Suppressor (Part# SS-DB9)
User configurable for use with male or female DB9 ports,
the SS-DB9 protects all 9 lines, plus D shell chassis.
Convenient DB9 input and output connects directly to
the protected port, obtaining a ground outlet from the
computer chassis. Surge suppression is handled with
balanced arrays of high-speed avalanche diodes that
divert excess energies created by electrostatic
discharges, faulty wiring or lightning away from network
interface connections.
