Functions and their Configuration INSYS ETHERNET 5.X

7.2.1 Serial interface

Set the parameters for the serial interface of the INSYS Ethernet.

Select the requested values in the fields "Baud rate" and "Data format".

Note

The interface parameters of the configuration PC must match the

interface parameters of the INSYS Ethernet.

Set the serial interface of the configuration PC at the HSComm

menu item "Interface".

Note

With the command AT*S<n> special baud rates may be set, which

may lead to communication problems.

If, by mistake, one of these settings was set permanently, you will

need to use the reset key to set the device to factory defaults.

Pertinent AT commands

AT*S<n>

Baud rate of the serial interface

AT*U<n>

Data format of the serial interface

7.2.2 Handshake Configuration

The handshake controls the data flow at the serial interface. If more data is sent than the

INSYS Ethernet or the connected data terminal can process, the data flow is stopped to

avoid a buffer overflow (data loss).

No handshake

This setting should only be used for devices which do not support handshake.

Note

Without handshake there is a risk of data loss. Waiting data is sim-

ply sent without considering the readiness of the remote terminal.

If the buffer overflows, a reduced data rate may be helpful, if neces-

sary.

Hardware handshake

The INSYS Ethernet controls the data flow via the separate control lines RTS/CTS.

Software handshake

The INSYS Ethernet controls the data flow with the help of control characters (XON: 0x11

/ XOFF: 0x13) via the data lines.
