Network Diagnostics
If checked it enables the Network Diagnostics Field in the Heartbeat message. The Network Diagnostics field is a fixed
32-byte field (one for each scanner in the network from scanner 0 (Master), to scanner 31). Each byte has the
following meaning:
0 = Scanner not expected
1 = Scanner OK
2 = Scanner expected but not present (not connected or possible network failure)
3 = Scanner Failure
Heartbeat Terminator String
This parameter signals the end of the Heartbeat message. It can be a string of up to 128 characters.
Selections: characters from
NUL
(00H) to
~
(7EH)
The Heartbeat Header String should be different from the Heartbeat Terminator String.
Main Serial Port Parameters
Main Port Communication Mode
The following communication modes can be selected when using the main serial port.
Selections:
Standard
MUX 32 slave
Siemens 3694
Siemens RK512
Standard
Standard is the normal mode for the Main Serial Interface. In this communication mode the following physical
connections are allowed:
RS232
RS485 full-duplex
Selecting Standard, the scanner will send out the data using the specified Handshake, but without any special protocol.
MUX32 Slave
MUX32 slave is the communication mode used for connections to a Multiplexer. For such a configuration the scanner
must be set with the same communication parameters (Baud rate, Parity, etc.) as the multiplexer.
In this communication mode, only the RS485 half-duplex physical connection is possible.
The following values are automatically set:
No parity
8 data bits
1 stop bit
3964
This communication mode is typically used for connections to a PLC. The following physical connections are allowed:
RS232
RS485 full-duplex
RK512
For RK512 protocol the following parameters must be set:
Checksum
Filler Character
Header Bytes
Priority
Filler Position
Main Port Electrical Interface
The Main serial interface is compatible with the following electrical standards:
Selections:
RS232
RS485
full duplex
