The OmniStar 400 is an IBM 5250 and 5250 Express compatible star repeater that replaces traditional twinax daisy chains and provides star configuration on twisted pair wiring. It supports distances of 3, 000 feet on each twisted pair and 5, 000 feet on twinax for a total of 8, 000 feet from the host. For cases that require additional distance, the OmniStar supports cascading of up to 4 stars.The host connects to the OmniStar via twinax or twisted pair RJ11/45 cable. The workstation connects to it via twisted pair RJ11/45 cable. Both the host and workstation ports support polarity configuration, which facilitates the usage of different balun types.The OmniStar diagnostics detect and display true port activity and parity errors. Each port is monitored for valid frame header patterns which are displayed via green Activity LEDs. The data is analyzed for errors; a detected error is displayed via a red Parity Error LED. These features assist in installation and monitoring of the OmniStar operation. |
