8-31 Address
Range: Function:
Application
dependent*
[Application dependant] Enter the address for the FC (standard) port.
Valid range: 1 - 126.
8-32 Baud Rate
Option: Function:
Baud rates 9600, 19200, 38400 and 76800 baud are valid for BacNet only.
[0] 2400 Baud
[1] 4800 Baud
[2] * 9600 Baud
[3] 19200 Baud
[4] 38400 Baud
[5] 57600 Baud
[6] 76800 Baud
[7] 115200 Baud
Default refers to the FC Protocol.
8-33 Parity / Stop Bits
Option: Function:
Parity and Stop Bits for the protocol par. 8-30
Protocol
using the FC Port. For some of the protocols,
not all options will be visible. Default depends on the protocol selected.
[0] * Even Parity, 1 Stop Bit
[1] Odd Parity, 1 Stop Bit
[2] No Parity, 1 Stop Bit
[3] No Parity, 2 Stop Bits
8-34 Estimated cycle time
Range: Function:
0 ms* [0 - 1000000 ms] In a noisy environments, the interface may be blocked by due to overload of bad frames. This
parameter specifies the time between two consecutive frames on the network. If the interface does
not detect valid frames in that time it flushes the receive buffer.
8-35 Minimum Response Delay
Range: Function:
Application
dependent*
[Application dependant] Specify the minimum delay time between receiving a request and transmitting a response. This is
used for overcoming modem turnaround delays.
8-36 Maximum Response Delay
Range: Function:
Application
dependent*
[Application dependant] Specify the maximum permissible delay time between transmitting a request and receiving a re-
sponse. Exceeding this delay time will cause control word time-out.
