FEATURES OF THE MODEL 4148 NORMAL/REDUNDANT SWITCH:
- Model 4148 data network switch will self-configure its connectivity based on the devices connected to it, or the user can override its connection status from a manual front panel pushbutton.
- Four front panel LEDs display the connectivity status and verify power connection, at all times.
- Copper network switch, LAN switch
AUTOMATIC OPERATION:
- During Normal mode, the origin device connected to Port D1 is connected to port COM1; and the device connected to port D2 is connected to port COM2.
- If the RTS signal is lost from the device connected to D1, the Model 4148 changes to Redundant Fallback mode and automatically broadcasts the data from the D2 device to both destination devices.
- If the RTS signal is lost from the device connected to D2, the Model 4148 automatically broadcasts the data from the D1 device to both the devices COM1 and COM2.
- One of the status LED's will be lit steady ON to reflect the connectivity status and signify that the unit is in Automatic Operation.
MANUAL OVERRIDE OPERATION:
- To override Automatic Operation, the user simply depresses the front panel pushbutton and holds it for 5 seconds and releases.
- The status LED previously lit steady ON begins to flash representing Manual Override operation. Momentarily depressing and releasing the pushbutton then allows the user to change the switch connectivity.
- To change back to Automatic Operation, depress and hold the pushbutton for 5 seconds and the switch will automatically connect.
