3095FC Communications
Ports Configuration
The communication ports of the 3095FC provide a link to a PC, such as one
running Rosemount User Interface Software or a host PC. The 3095FC can
have up to three communication ports.
General Tab
See Figure 3-4.
1. Select Device > Comm Ports > General Tab
1. Select the Port that the 3095FC is using to communicate. Enter the
10-character Comm Tag name for identification of the
communications port.
2. Select the transmit and receive data Baud Rate in bits per second.
3. Select the Parity radio button if checks are to be performed by the
communications controller.
4. Select the number of Data Bits contained in an asynchronous byte, or
character. This number is typically 8.
5. Select the number of Stop Bits contained in an asynchronous byte, or
character. This number is typically 1.
6. Select if the RTS/CTS Handshaking is enabled.
7. Enter the Key On Delay to define the number of seconds to delay
after turning the RTS signal on before beginning transmission. For
older radios, the Key On Delay may need to be set as high as 0.2
seconds. For radios designed for data transmission, no more than
0.02 second should be required.
8. Enter the Key Off Delay intervals defining the period to delay before
turning the RTS signal off once a valid message has been sent. The
default of 0.01 seconds should be sufficient for most radios.
9. Enter the Valid Receive Ctc (Counter) to log the number of valid
OpCodes received by the device on the communication port. The
value in the counter can be preset or cleared.
