Remote Serial Com Port

In this scenario a Serial device must be connected to a PC but the device is too far away from the PC.

The Z-Key can be used for extend the serial port using the ethernet connection:

Also a connection through internet can be made (typically for remote maintenance of machines, PLC etc...):

For internet communication the Router connected to the Z-KEY must have a static ip address.

NOTE:

Z-KEY, in Remote serial com port mode, supports one PC connection at a time.

NOTE:

For using the ZModem serial protocol with Z-KEY through internet, remember to activate the

protocol crash recovery option.

13.1.

If a PC program has only the serial port support but you need to exit from the ethernet you can install the

Serial to Ethernet driver freely supplied by Seneca.

With this driver installed a couple of virtual serial port is created, using these serial ports from a pc

software the serial traffic will pass through ethernet. After that the Z-KEY will convert the ethernet traffic to

serial through the real serial port, also Z-KEY will reconvert to ethernet the serial communication responses.
