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.

•DB25 Male to RJ45 Modular Adapter (Item# RJ25P-232)

Preconfigured for use with the SeaLINK+16.VC, this modular adapter converts the RJ45 RS-232

pinout from the SeaLINK+16.VC to a DB25 male RS-232 serial port. Standard CAT5 patch cables can

be used to extend the serial port up to 50 feet away from the SeaLINL+16.VC.

•DB9 Male to RJ45 Modular Adapter (Item# RJ9P8)

The RJ9P8 includes an RJ45 connector and converts it to a DB9 Male connector, which allows the

use of standard twisted pair cabling. The RJ9P8 ships unassembled and can be configured for

virtually any pin out.

•DB25 Male to RJ45 Modular Adapter (Item# RJ25P8)

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.

3rd Party Software

For the most up to date information on third party software support, please visit

https://www.sealevel.com/support/3rd-party-software-support/.

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.

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.

RS-485 Data -

DCD, DSR, and RI are inputs that are not brought out on the RJ45 connector. DSR and DCD are

biased active, and RI is biased inactive.

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.
