Card Setup
Clock Modes
The COMM+8.cPCI employs a unique clocking option that allows the end user
to select from divide by 4 and divide by 1 clocking modes. This mode is
selected at J1.
To select the Baud rates commonly associated with COM: ports (i.e. 2400,
4800, 9600, 19.2, … 115.2K Bps) place the jumper in the divide by 4 mode
(silk-screen D4).
Figure 1-Clocking Mode ‘Divide By 4’
To select the maximum data rate (460.8K bps) place the jumper in the divide by
1 (silk-screen D1) position.

Address and IRQ selection
The COMM+8.cPCI is automatically assigned I/O addresses and IRQs by your
motherboard BIOS. Only the I/O address may be modified by the user.
Adding or removing other hardware may change the assignment of I/O
addresses and IRQs.

Installation

Installation
Operating System Installation
For Windows Users
Start by choosing Install Software at the beginning of the CD. Choose
Asynchronous COM: Port Software, SeaCOM.
OtherOperating Systems
Refer to the appropriate section of the Serial Utilities Software.
System Installation
The COMM+8.cPCI can be installed in any of the cPCI expansion slots and
contains configuration options for each port that must be set for proper
operation.
1. Turn off PC power. Disconnect the power cord.
2. Locate an available cPCI slot and remove the blank metal slot cover.
3. Gently insert the COMM+8.cPCI into the slot. Make sure that the adapter
is seated properly.
4. Replace the cover.
5. Install the Cable (CA-191)
6. Connect the power cord.
Installation is complete.

Technical Description
Sealevel Systems COMM+8.cPCI Page 5
Technical Description
The Sealevel Systems COMM+8.cPCI provides a PCI interface adapter with
8RS-232 asynchronous serial ports for industrial automation and control
applications.
The COMM+8.cPCI utilizes the 16C864 UART. This chip features
programmable baud rates, data format, interrupt control and industry leading
128-byte transmit and receive FIFOs.
Connector Pin Assignments
DB-25 (RS-232 DTE) (DB25 MALE)
Signal Name Pin # Mode
GND Ground 7
TD Transmit Data 2Output
RTS Request To Send 4Output
DTR Data Terminal Ready 20 Output
RD Receive Data 3Input
CTS Clear To Send 5Input
DSR Data Set Ready 6Input
DCD Data Carrier Detect 8Input
RI Ring Indicator 22 Input
Technical Note: Please terminate any control signals that are not going to be
used. The most common way to do this is connect RTS to CTS and RI. Also,
connect DCD to DTR and DSR. Terminating these pins, if not used, will help
insure you get the best performance from your adapter.

Appendix A -Troubleshooting
Sealevel Software is supplied with the Sealevel Systems adapter and will be
used in the troubleshooting procedures. By using this software and following
these simple steps, most common problems can be eliminated without the need
to call Technical Support.
1. Identify all I/O adapters currently installed in your system. This includes
your on-board serial ports, controller cards, sound cards etc. The I/O
addresses used by these adapters, as well as the IRQ (if any) should be
identified.
2. Make sure the Sealevel Systems adapter is securely installed in a
motherboard slot.
3. When running DOS or Windows 3.x refer to the supplied Sealevel
Software and this User Manual to verify that the Sealevel Systems adapter
is configured correctly. This software contains a diagnostic program ‘SSD’
that will verify if an adapter is configured properly. This diagnostic
program is written with the user in mind and is easy to use.
4. For Windows 95/98/ME/NT/2000/XP, the diagnostic tool ‘WinSSD’ is
installed in the SeaCOM folder on the Start Menu during the setup process.
First find the ports using the Device Manager, then use ‘WinSSD’ to verify
that the ports are functional.
5. Always use the Sealevel Systems diagnostic software when
troubleshooting a problem. This will eliminate any software issues from
the equation.
