Introduction The Sealevel COMM+2.LPCIe (Item# 7205e) provides a PCI Express 1.0a compliant interface adapter with two asynchronous serial ports for industrial automation and control applications. The serial ports are field selectable for RS-232, RS-422, or RS-485 and support data rates to 921.6K bps. Configure both ports as RS232 for standard serial COM: port requirements. Choose the RS-422 mode for long distance device connections up to 4000ft. where noise immunity and high data integrity are essential.
Before You Get Started What’s Included Depending on the PC bracket ordered, the 7205e is shipped with the following items. If any of these items are missing or damaged, please contact Sealevel for replacement. COMM+2.
Hardware Configuration There are two sets of 7-position dipswitches on the board that are used to set the electrical interface, termination and biasing. The dipswitch located at ‘SW1’ is labeled ‘PORT 1’ and configures the first serial port. The dipswitch located at ‘SW2’ is labeled ‘PORT 2’ and configures the second serial port. The labels and description of the function for each switch are detailed in the following table.
Electrical Interface Modes Each port on the 7205e can be individually configured for RS-232, RS-422, or RS485 mode. The first two switches labeled ‘M1’ and ‘M0’ are used to select the electrical interface. To simplify installation and testing the board is shipped in RS422 mode. Use the settings in the table below to assist you in configuring the electrical interface.

Hardware Description PCI Express Board The 7205e is a low profile PCI Express 1.0a compliant board via single-lane x1 slot. It can be used in any single- or multi-lane PCI Express slot. It is available in standard height PCI Express as item# 7205eS. DB25M Board Connector The board integrates a DB25 male connector for interfacing the two serial ports via the included cable. DB9M Serial Connectors The 7205e ships with a two-port cable (Item# CA203) that includes a pair of DB9 male serial connectors.
Electrical Specifications Each serial port utilizes a 16C950 UART featuring programmable baud rates, data format, interrupt control and industry-leading 128-byte transmit and receive FIFOs. This high-performance UART includes 9-bit framing support and is fully software compatible with legacy 16550 applications. In addition, the 14.7456 oscillator and UART’s flexible clock prescaler supports the widest range of standard and nonstandard baud rates to 921.6K bps.
Cable Pin Assignments The 7205e includes a cable (Item# CA203) with a DB25 female connector terminating to a pair of DB9 male connectors. The DB25F connector on the cable plugs into the DB25M connector on interface board. The DB9M connectors are compatible with a variety of serial peripherals. The pin assignments for the supported electrical interfaces are shown in the tables below. RS-232 (DB9 Male) These RS-232 pin assignments meet EIA/TIA/ANSI-574 DTE specifications for DB9 type connectors.
Baud Rates and Oscillator Value The 7205e utilizes a 14.7456MHz oscillator, which is automatically entered by the SeaCOM driver under Windows 2000/XP/Vista operating systems. The oscillator value can be found in the COM port properties of Device Manager under the ‘Advanced Tab’. The high-speed oscillator and the UART’s flexible clock prescaler support a wide range of standard and non-standard baud rates.

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. - 24 - COMM+2.
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 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 are the standard means of serial data communication for PC compatible and PS/2 computers.
