Introduction

Overview

The COMM+16.PCIe provides sixteen RS-232 asynchronous serial ports capable of data rates to 460.8K

bps. Each RS-232 port implements all modem control signals for maximum compatibility with a wide range

of peripherals. The board is PCI Express X1 compliant and can be used in any x1, x2, x4, x8, or x16 PCI

Express slot. The board utilizes 16C854 UARTs to provide 128-byte Tx/Rx FIFOs for maximum reliability in

data intensive applications. Standard operating temperature range is 0°C to 70°C and extended

temperature range (-40°C to +85°C) versions are available.

The board ships with two 36" ‘spider’ cables that terminate to a total of sixteen DB-25M connectors (Item#

7161e) or sixteen DB-9M connectors (Item# 7161e-DB9). Additional ordering options allow the choice of

UARTs for custom baud rates and 9-bit protocols.

The COMM+16.PCIe is designed to be used with a variety of operating systems including Microsoft

Windows and Linux. Sealevel’s SeaCOM software uses the standard Windows WIN32 API and eliminates

proprietary DLL files. This allows Sealevel SeaCOM software to maintain 100% compatibility with Microsoft

Windows applications. SeaCOM software also includes sample code and utilities to simplify application

development.

SeaCOM Software Installation

Do not install the board until the software has been fully installed.

Operating System Installation

For Windows Users (Windows 98/ME/NT/2000/XP Operating Systems)

Begin by locating, selecting, and installing the SeaCOM software from the Sealevel software driver database.

The SeaCOM software can also be downloaded from the 7161e - product webpage.

Other Operating Systems

Refer to the appropriate section of the Serial Utilities Software.

Linux Installation

Refer to Linux Archives - Sealevel. This link contains valuable information on installing your serial

adapter in the various Linux releases. Also included is a series of files explaining proper Linux syntax and

typical Linux serial implementations. The SeaCOM for Linux v7.3.2 can be downloaded from Sealevel’s

website (Software: SeaCOM - Linux - Sealevel).

For additional software support, please call Sealevel Systems’ Technical Support, (864) 843-4343. Our

technical support is free and available from 8:00AM-5PM Eastern Time, Monday through Friday. For

email support contact: mailto:support@sealevel.com.

Third Party Software Support

Third party software support for many HMI/MMI and other process control software is also available from

the Sealevel software database. For the most up to date information on third party software support,

please visit the 3rd-Party Software Archives - Sealevel.

To install Sealevel Systems software, you must log in as an administrator or have administrator

privileges in Windows.

Hardware Installation

The COMM+16.PCIe can be installed in any available x1, x2, x4, x8, or x16 PCI Express slot.

Do not install the board until the software has been fully installed.

1. To avoid accidental damage, be sure to follow proper ESD procedures by grounding yourself

and the serial adapter.

2. Turn off PC power and disconnect the power cord.

3. Remove the PC case cover.

4. Locate an available PCI Express slot and remove the blank metal slot cover.

5. Gently insert the PCI Express serial adapter into the slot making sure the adapter is seated

properly.

6. Replace the screw (or spring clip) to secure the card in the PC case. This step is required to

ensure FCC Part 15 compliance.

7. Replace the PC cover and connect the power cord.

8. Turn on the PC and login as a user with Administrator privileges, if applicable.

9. The software drivers installed during setup will automatically recognize and configure the

serial adapter.

10. You should see two or more “Found New Hardware Wizard” dialog boxes, indicating the actual

COM ports are being created.

11. Next, view your system’s Device Manager.

The installation will repeat once for each COM port created (a total of 17 times on the

COMM+16.PCIe). This is a limitation in the way Windows installs serial devices.

12. You should have new COM: ports in the Ports (COM & LPT) Device Class indicating the

installation was successful.

13. You can access your new COM: port by using the assigned COM: identifier. This assignment will

vary from system to system.

14. To verify operation, use Sealevel Systems supplied WinSSD diagnostic utility. WinSSD can be

found in the Start menu, under All Programs, and then under the Sealevel SeaCOM programs

group.

The COMM+16.PCIe is now ready for use.
