Introduction
The Com-Server++, 58665 and Com-Server 3x Isolated, 58662
represent a uniform platform for linking serial interfaces such
as RS232, RS422/485 to TCP/IP networks. The standard mo-
des for transparent tunneling of serial data (e.g. through vir-
tual COM ports) are implemented. The Com-Server++ includes
additional protocols and modes (e.g. UDP, TCP client, FTP cli-
ent/server, etc.) as well as expanded functions for structuring
the data interchange.
In addition to all the standard applications implemented in
the firmware, this reference manual also describes the inte-
gration possibilities for your own applications.
