Interpreting Screen Displays

Check Output
Ports
Evaluate the output error indications based on whether output was being displayed
successfully:
Output data has been displaying successfully and has suddenly stopped:
Check flow control and logical receiver memory utilization, as indicated in
the following Show Status screens. Frequently, overflow problems occur
within the software on the external device; rebooting the attached PC may
clear the problem. If the output PC is handling other processing-intensive
tasks, data flow from the IDR V1000 to the PC could be temporarily
blocked, causing a buffer overflow in the IDR V1000.
Output data has not been successfully displayed from a newly installed receiver:
Check cable connections, then verify incoming signal quality. Verify that
appropriate values are set for the serial ports. Verify that the communications
software on the external device is set up with baud rate, parity, and flow
control matching the IDR V1000.
Show Status/
Logical Receivers
The first of a series of screens within the Show Status main topic shows the current
activity of the logical receivers and their assigned ports. (R0 for stat mux or
transparent async mode; R1 through R3 in stat mux mode only).
