Virtual Serial Server

The Virtual Serial Server mode is used to provide a TCP interface, via satellite or cell, to a serial device. The satellite terminal must have satscada firmware release 1.3.9 or better. The Virtual Serial Server mode does not require the end points to use a request/response protocol. The over-the-air data transfer is bi-directional.

:!: You will need to discuss using this mode with Bentek since there is some satscada server configuration required related to security and ip port setup.

The connection is enabled using the first check box.

The second check box permits virtual serial transfers to override other connections muxed to the same serial port. If override is used then enter other types of connections first in other forms then add the virtual serial connection. The validation rules will not permit override unless there are other serial ports specified that are muxed to this port.

OTA Port Over-the-air port number in the range 1 to 2.
IP Port Over-the-air IP port number. Typically 20000 or 30000. Must be same as used by the server.
COM Port Serial port number in the range 0 to 1.
Routing Channel to be used for the data transfer: cell only, satellite/cell fail-over, or satellite only.
Override Duration of override after last virtual serial transfer (msec).

Example: Virtual Serial Server with OTA Modbus Slave

In this example one modbus slave (IP Client) is connected over-the-air (satellite or cell) to a SAT130 terminal configured as a virtual serial server. The PLC connected to the SAT130 via RS-232 is a modbus master. Even though modbus is used in this example the Virtual Serial Server mode can use any protocol. Arbitrary arrays of bytes can be transferred bidirectionally.
