Hardware Description Ruggedized Overmold Enclosure The 2105R is built for harsh conditions and features a military-grade, ruggedized, overmolded enclosure. This improves the reliability and durability in industrial and mobile applications. DB9M Serial Connector The 2105R includes a DB9 male serial connector on one end of the device. The pin assignments for this connector are detailed in the following Electrical Specifications section.
Electrical Specifications The SeaLINK+232-DB9 utilizes a USB UART. This chip features programmable baud rate, data format, 128-byte dual-port TX buffer, and 384-byte dual-port RX buffer. The RS-232 transceiver supports data rates up to 921.6K baud. Refer to Appendix C for cable length limitations.
Technical Specifications Dimensions Overall cable length, including connector, is 44” Length Width Height 2.14” 1.4” 0.63” 5.44 cm 3.55 cm 1.60 cm Environmental Specifications Specification Temperature Range Humidity Range Operating 0º to 70º C (32º to 158º F) 10 to 90% R.H. Non-Condensing Storage -50º to 105º C (-58º to 221º F) 10 to 90% R.H.
Appendix A – Troubleshooting The adapter should provide years of trouble-free service. However, in the event that it appears to be functioning incorrectly, the following tips can eliminate most common problems without the need to call Technical Support. 1. Ensure that the Sealevel Systems SeaCOM software has been installed on the machine, so that the necessary files are in place to complete the installation. To confirm installation, click on the Windows ‘Start’ button and then select ‘All Programs’.
On the ‘Port Information’ tab, select the COM port you want to test and click on the ‘Open’ button. (See image below) Click the ‘Settings’ button to open the COM Properties menu. Change your parameters to 9600 bits per second, 8 data bits, no parity, 1 stop bit, and no flow control, as pictured below. Click ‘Apply’ and ‘OK’. © Sealevel Systems, Inc.
Click on the ‘Start’ button. If testing RS-485, be sure that ECHO is enabled. (See image below) If the COM port is working properly, the green light will glow and the Transmit Frames and Receive Frames will increase. The Tx and Rx Data Rates will show the calculated data rate. (See image below) You can continue testing this port with different configurations or proceed with testing other ports, if necessary.
Appendix B – How To Get Assistance Begin by reading the Troubleshooting Guide (Appendix A). This will help solve most common problems. 1. When calling for technical assistance, please have the device installed and ready to run diagnostics. If possible, have your user manual and current adapter settings ready. 2. The Sealevel website is an excellent resource located at www.sealevel.com.
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 RS232 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/TIA574 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 are the standard means of serial data communication for PC compatible and PS/2 computers.
Appendix E – Compliance Notices Federal Communications Commission Statement This equipment has been tested and found to comply with the limits for Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
