Det-Tronics EagleVision - PC - Manual (Page 16)

Com Port defines which PC serial port is connected to the gateway.
Clicking on the button next to Com Port initiates a routine in which the
software systematically tries all valid combinations of baud rate, data
bits, and parity. If a connection is successfully established, the software
will fill in the appropriate values.
Writes Count tracks the number of outgoing messages to the gateway.
Reads Count tracks the number of responses. These two numbers
should track each other, however, a small disparity does not necessari-
ly indicate a problem.
Average Poll Time is the amount of time for the gateway to respond
to the message.
This data indicates communication errors. These values can be helpful
in diagnosing communication problems.
CRC (Cyclical Redundancy Check) is an error checking method. This
field is incremented when the calculated CRC value is different than the
transmitted value. This error is typically caused by incorrect serial com-
munication settings.
Data. This field tracks the number of response messages that have the
wrong data size.
Com. This field tracks the number of serial communication errors report-
ed by the operating system.
Command. This field tracks the number of Modbus error responses.
This can occur if the gateway is not configured properly. Check the set-
ting of the Main/Aux gateway DIP switch.
Timeouts. This number is incremented each time the gateway does not
respond to the message from the OIS.
When correct communication is established, the read and write counts
should match, with zeros displayed in the Error boxes.
