3.2.4.1 Host/Device Idle Protection (ADAM-4570 only)

When building up a system, users sometimes face the following problems. The system crashes because the serial/Host device breaks down; the application program fails or the cable between the host device and the ADAM-4570 breaks etc. For keeping the stability of system, the users usually have to spend lots of efforts to build up “Redundant” function. Now the ADAM-4570 provides new powerful functions to help users to build up it fast and easily. Focusing on Host PC, serial device, ADAM-4570, the new functions are: Host idle switch, device idle switch and auto-reconnect (refer to Chapter 3.4.4).

Host Idle Switch Mode

When the application program which is running in host PC fails, the ADAM-4570 and the serial device always “Hang up”. The data can not be sent to other PC. The purpose of the “Host idle switch” mode is to prevent this system hang-up from occurring due to the above problems. If the application program fails, the ADAM-4570 will cut off the connection between the host PC and the ADAM-4570. Another PC can then start to access the same ADAM-4570. Below illustrates the behavior of the ADAM-4570.
