Introduction
The Sealevel Systems SeaLINK+16.VC (Item# 2167) is a USB device that equips the PC with 16 RS-232 or
RS-485 Asynchronous serial ports. The SeaLINK+16.VC supports RS-232 data rates up to 115.2K bps and
RS-485 data rates up to 921.6K bps. The box does not need to be opened nor are there any dipswitches to
set.
With the unique VersaCom multi-interface connector design included on the SeaLINK+16.VC, 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 a port-by-port basis. The SeaLINK+16.VC also
provides two USB 1.1 downstream ports (fully rated at 500 mA per port) for conveniently connecting
additional SeaLINK+16.VC devices or other USB peripherals.
The SeaLINK+16.VC is designed to be used with a variety of Operating Systems including Windows
98/ME/2000/XP. The SeaCOM API (Application Programmer Interface) included on CD with the
SeaLINK+16.VC provides a variety of useful high-level function calls implemented as a Windows dynamic
link library (DLL). In addition to the API, SeaCOM includes sample code and utilities to simplify software
development.

Software Installation Instructions
Windows 98/ME/2000/XP/Vista™ Operating Systems
Do not connect the device to a USB port until the software is installed.
1. Begin by locating, selecting, and installing the correct software from the Sealevel software driver
database.
2. Select the Part Number (2167) for your device from the listing.
3. The setup file will automatically detect the operating environment and install the proper
components. Follow the information presented on the installation screens that follow.
4. A screen may appear with the declaration: “The publisher cannot be determined due to the
problems below: Authenticode signature not found.” Please select the ‘Yes’ button and proceed
with the installation. This declaration simply means that the Operating System is not aware of the
driver being loaded. It will not cause any harm to your system.
5. During setup, you may specify installation directories and other preferred configurations. This
program also adds entries to the system registry that are necessary for specifying the operating
parameters for each driver. An uninstall option is included to remove the driver and all registry/INI
file entries from your system.
6. Proceed with the physical installation of your SeaLINK USB serial adapter.
Windows NT is not USB aware and thus cannot support this device.

Physical Installation
The SeaLINK+16.VC can be connected to any spare USB port.
Do not connect the device to a USB port until the software is installed.
1. Connect the SeaLINK+16.VC to external power using the included TR101 power supply.
2. Connect the SeaLINK+16.VC to a USB port with the supplied CA179 USB device cable.
3. The software drivers installed during setup will automatically recognize and configure the device.
4. You should see one or more “New Hardware Found” windows, indicating the actual device being
created.
The installation will repeat twice for each COM port (a total of 32 times on the SeaLINK+16.VC).
This is a limitation in the way Windows installs external serial devices.
5. Next, view your system’s Device Manager.
6. You should have new COM: ports in the Ports (COM & LPT) Device Class indicating the installation
was successful.
7. You can access your new COM: port by using the assigned COM: identifier. This assignment will
vary from system to system.
8. To verify operation use Sealevel Systems supplied WinSSD diagnostic utility. WinSSD can be found
in the Start, Programs group.
The SeaLINK+16.VC is now ready for use.

Interface Selection
With the unique VersaCom multi-interface connector design, both RS-232 and two-wire RS-485 signals are
always present and active on the RJ45 connectors. Simply select the appropriate pin out for RS-232 or two-
wire RS-485 on each individual port. The unused interface on each connector should be left unconnected.
All inputs have appropriate biasing to keep them in an inactive state. If the unused interface pins are
connected to a cable, the outputs will attempt to drive the lines while the inputs will attempt to interpret any
voltage on the line as data, which can limit cable length and may result in communication failures.
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.
