Specify Whether to Include the Stream Identifier in each Data Packet

Of the Trio radio series with which Geo SCADA Expert can communicate using the Advanced Trio Diagnostics driver, radios other than D Series can use a Stream Identifier (SID) code to identify the particular message stream that is being used.

Select the Enable Trunk Stream Connection check box on the Trio Diagnostics Advanced tab if the radio port that Geo SCADA Expert uses to communicate with the Trio radio is one of the following:

• The System or Diagnostics/Programming port on an E, K, or M Series radio
• The eDiags (Ethernet) port on a E, J, or Q Series radio with which Geo SCADA Expert communicates using TCP/IP
• A Serial port that is configured as a Trunk port.

With such communications, use the SID Code field on each Advanced Trio Diagnostics Radio Form to specify the actual message stream used by each radio (see Specify the Stream Identifier that Prefixes Messages Sent to and from the Radio ).

Clear the Enable Trunk Stream Connectioncheck box if:

• The radio via which Geo SCADA Expert transmits requests to other radios is a D Series radio

or:

• The serial port that Geo SCADA Expert uses to communicate with the radio is a Serial port that is configured as a User port.
