TAC Remote Serial Port Driver
0FL-3955-000
Software Installation Instruction
INTRODUCTION
The TAC Xenta 911 has an RS-232 serial port that can be
used by Windows programs such as TAC Vista via the
Remote Serial Port Driver. This enables TAC Vista to
communicate with devices which are normally connected
directly to the computer via networks using TCP/IP.
Remote Serial Port Driver (RSPD) is a Windows NT/2000/XP
program that is installed by running the RSPDINST.EXE
installation program. The installation program will install a
service in the operating system that transports serial
communication via TCP/IP through a Network Interface Card
to a serial port on the TAC Xenta 911.
Configuration of the serial port, IP addresses and IP ports is
done using the RSPD Control applet.
TAC Vista can simultaneously communicate with devices on
both the LonTalk and serial ports.
The TAC Xenta 911 supports 8 data bits, no parity and 1 stop
bit (8-N-1).
INSTALLATION
RSPD is available for download from Tarai and is supplied on
the TAC Software CD. Installation is started by executing the
RSPDINST.EXE program. Follow the on-screen instructions in
order to complete the installation.

There should now be an RSPD service in the
Service Manager in Windows.
ENGINEERING
The RSPD service has the capability to create
serial ports (COM ports) for use by Windows
programs. A Serial port that is not directly
associated with a physically installed serial port
on the computer is called a Virtual Serial Port.
The TAC RSPD Control dialog
A maximum of 256 serial ports can be used.
This is the maximum number of TAC Xenta 911
devices that can be used with RSPD.
Each serial port, reflects one TAC Xenta 911. For
each virtual serial port the IP adress and the IP
ports of the associated TAC Xenta 911 must be
configured. Configuration is done using the
RSPD Control dialog.
Click Add Port to configure RSPD to create a new virtual
serial port
When configuration is completed, click Start Service (in the
TAC RSPD Control dialog) to start the RSPD service. The
RSPD service will create the virtual serial ports in Windows.
Other Windows programs will now be able to use them.
Note!
The RSPD service must be stopped in order to change the
configuration.
Select the port name, type in the IP adress of the TAC
Xenta 911 and, if necessary, change the Data Port and the
Update Port. The Data Port and the Update Port are the
ports that need to be open for TCP if firewalls are being
used between the computer and the TAC Xenta 911.
Any programs using the virtual serial ports MUST be closed
before stopping the RSPD service.
Startup Type should be set up to Automatic so that RSPD
starts automatically when Windows starts.
