2.3 Serial Number of the Async Concentrator

It is the unique number identifying an Async Concentrator and written on a sticker which can be found at the left side of the rear panel of each Async Concentrator.

User has to type in the serial number when setup the driver in the system. Under DOS, user can use "Auto-Search Serial No." function of the setup program to detect the serial number(s) of all the existing Async Concentrator(s) for convenience without typing the serial number(s) one by one.

Under UNIX, "Auto-Search" function is not available at the time of driver installation due to that the C360 driver is not in the UNIX system at that time.

2.4 LED Indicators

C360 Control Board

The green link LED labeled Lk lights up to indicate that a valid 10BASE-T link beat is established. It should be ON under normal operating condition. If the LED remains off after power is applied, check for a proper RJ-45 connection.

Async Concentrator

After powering on the Async Concentrator, red indicator S0 "ON" and S1 "OFF" means normal initialization status of the Async Concentrator. And green indicator Tx and red indicator Rx will flash periodically and either more frequently if C360 driver is not started or less frequently if C360 driver is started.

Indicator Tx and Rx show the status of transmitting and receiving data. If the indicator Tx is ON, then some data is transmitted from the Async Concentrator. If the indicator Rx is ON, then some data is received by the Async Concentrator. On the other hand, if indicators Tx and Rx are all OFF, then no data is transferring at that time.

As to the signals' status of each serial port, please use "mini tester" to monitor.
