The checkbox is cleared by default.
Enable self-address
Selects the checkbox to accept and process any packets that contain the destination address 65532 (FFFCh).
This provides a mechanism for a master to discover the configured address of the controller when connected point-to-point. In a network environment, the checkbox must be left cleared.
Master node
Specifies the master node address. The addresses for node 1, 2, 3, and 4 are available when master address validation is enabled.
The address is from 0 through 65519.
Master node 0
 is available by default.
Media

.
Confirmation timeout
Specifies the time, in milliseconds, for which the controller waits before resending the unsolicited response.
The value is from 20 ms through 1,400 s.
Stop bits
Specifies the number of stop bits per character. Options include

 and
2
. 1 is the default option.

  • Clear the checkbox to turn off Request LL confirmation. The primary frames are sent with the function code
    FC_UNCONFIRMED_USER_DATA (4)
    .
Send LL confirmation
Turns on or turns off Send LL confirmation.
  • Select the checkbox to turn on Send LL confirmation. The optional secondary frame is sent with the function code
    FC_NACK (1)
     or
    FC_NOT_SUPPORTED (15)
    .
  • Clear the checkbox to turn off Send LL confirmation. The optional secondary frame is not sent.
Message retries
Specifies the number of message resend attempts. The value is from 0 through 255.
Pre-transmission delay
Specifies the amount of time before the
Micro800
 controller sends the packet.
The value is from 0 through 65535. The default value is 0.
RTS off delay
Specifies the delayed amount of time between the end of a transmission and the Ready To Send (RTS) drop. It is available when
Half Duplex without continuous carrier (RTS/CTS)
 is selected for
Control line
.
The value is from 0 through 32767. The default value is 0.
