Introduction SeaLINK DIN Rail USB serial interface adapters are the perfect way to add RS-232, RS-422, or RS-485 serial peripherals such as barcode scanners, serial displays, and data acquisition modules to any USB port. Offering one or two DB9M serial ports, models are available for RS-232, RS422/485, and RS-232/422/485 interfaces. Serial ports are configurable via dip switches accessible through the case. There is never a need to open the enclosure, which simplifies field installation and service.
Before You Get Started What’s Included All SeaLINK DIN rail USB serial adapters ship with the following items. If any of these items is missing or damaged, please contact Sealevel for a replacement.

SeaLATCH™ USB SeaLINK USB serial adapters integrate the patent-pending SeaLATCH USB port, which is fully compatible with standard USB cables. When used with the included USB cable (Item# CA356) with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection. © Sealevel Systems, Inc.
SeaLATCH Locking USB Cables SeaLATCH USB Connectors SeaLATCH locking USB cables integrate a small thumbscrew into each USB connector. SeaLATCH USB cables are fully interchangeable with standard USB cables. The thumbscrew provides a secure metalto-metal connection preventing accidental disconnection. SeaLATCH USB cables are available in three configurations. Item# CA356 The CA356 is a 72” USB cable with a SeaLATCH type B connector and a standard USB type A connector.
Hardware Configuration RS-232/422/485 Multi-Interface Products Items# 2109, 2113, 2209, 2213 Dip switches on SeaLINK USB multi-interface serial adapters provide the ability to communicate with RS-232, RS-422 or RS-485 devices. These switches are also used to set RS-485 enable modes and termination options. Single port models have a single eight-position dip switch. Two port models have a pair of eight-position dip switches allowing each port to be individually configured.
Dip Switches (continued) RS-485 is ideal for multi-drop or network environments. RS-485 requires a tri-state driver that will allow the electrical presence of the driver to be removed from the line. The driver is in a tri-state or high impedance condition when this occurs. One of the unique features of SeaLINK USB serial devices is the ability to be RS-485 compatible without the need for special software or drivers (RS-485 auto-enable).
RS-422/485 Products Items# 2112, 2212 Dip switches on SeaLINK USB RS-422/485 serial adapters provide the ability to communicate with RS-422 or RS-485 devices. These switches are also used to set RS-485 enable modes and termination options. Single port models have a single eight-position dip switch. Two port models have a pair of eight-position dip switches allowing each port to be individually configured. All configuration changes can be made without opening the enclosure.

RS-232 Products Items# 2111, 2211 SeaLINK RS-232 only serial devices do not require any hardware settings and the enclosures should not be opened. All configuration (e.g., baud rate, parity, etc.) settings can be made through the SeaCOM software driver or application interface. Proceed with installing the SeaCOM software driver included on the software CD that shipped with the device. Be sure to install all software prior to plugging the SeaLINK USB device into a USB port. © Sealevel Systems, Inc.
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. Start Windows. 2. Insert the Sealevel Software CD in to your CD drive. 3. If ‘Auto-Start’ is enabled the installation window will automatically appear. Otherwise, navigate to the root directory of your CD drive and double-click the ‘autorun.exe’ application to launch the installation window. 4. Select ‘Install Software’. 5.
Physical Installation SeaLINK USB serial adapters can be connected to any spare USB port. Do not connect the device to a USB port until the software has been installed. 1. Connect the SeaLINK USB serial adapter to a USB port using the supplied USB device cable. 2. The software drivers installed during setup will automatically recognize and configure the device. 3. You should see one or more “New Hardware Found” windows, indicating the actual device being created. 4.

Appendix A - Troubleshooting Sealevel Software is supplied with the Sealevel Systems adapter and may be used in the troubleshooting procedures. Using this software and following these simple steps can eliminate most common problems without the need to call Technical Support. 1. If your adapter isn’t working, first check to make sure that USB support is enabled in the System BIOS and it is functioning properly in the operating system.
Appendix B - How To Get Assistance Begin by reading through the Trouble Shooting Guide in Appendix A. If assistance is still needed please see below. When calling for technical assistance, please have your user manual and current adapter settings. If possible, please have the adapter installed in a computer ready to run diagnostics. Sealevel Systems provides an FAQ section on its web site. Please refer to this to answer many common questions. This section can be found at http://www.sealevel.com/faq.
Appendix C – Electrical Interface RS-232 RS-422 RS-485 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.
