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.

The RSPD service has the capability to create	The TAC RSPD Control dialog

programs. A Serial port that is not directly associ-
ated with a physically installed serial port on the
computer is called a Virtual Serial Port.
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
