2.3.1 Enabled
This parameter specifies if the port will be used. If the parameter is set to No, the
port is disabled. If the parameter is set to Yes, the port is enabled.
2.3.2 Type
Type : Master #M=Master, S=Slave
This parameter defines if the port will emulate a master or a slave device. Enter
Master if the port is to emulate a master device or Slave if the port is to emulate a
slave device.
2.3.3 Local Station ID
This parameter specifies the local station ID for all DF1 messages sent from this
master port. A value of 255 is not permitted as this is the broadcast address.
Enter a value in the range of 0 to 254.
2.3.4 Protocol
Protocol : Full #F=Full-Duplex, H=Half-Duplex
This parameter specifies the DF1 protocol to be used on the port. Enter Full for
full-duplex communications or Half for half-duplex communications.
2.3.5 Termination
Type
Termination Type : CRC #B=BCC, C=CRC
This parameter specifies error checking for all DF1 messages. Enter CRC or
BCC.
2.3.6 Baud
Rate
This is the baud rate to be used on the port. Enter the baud rate as a value. For
example, to select 19K baud, enter 19200.
2.3.7 Parity
None, Odd, Even
Parity is a simple error checking algorithm used in serial communication. This
parameter specifies the type of parity checking to use.
All devices communicating through this port must use the same parity setting.
2.3.8 Data
Bits
7 or 8
This parameter sets the number of data bits for each word used by the protocol.
All devices communicating through this port must use the same number of data
bits.
