To use the IP learning mechanism, you do not need to know the current address of
IR-IP LAN interface, but only the prescribed IP address.

The IP address is actually retrieved from the ARP frames sent during pinging to
locate the ping destination, not from the ping frames.
To ensure that the process is correctly performed, it is recommended to check the
contents of the ARP table before starting the ping utility, to make sure that it does
not contain the address to be assigned to the IP router LAN interface.

Assigning a LAN IP Address to a New IR-IP
The following procedure enables you to configure the LAN IP address of a new
IR-IP router, i.e., a router using the default parameters (see the

2. Turn ASMi-52 on and monitor the IP router indicators:
The LINK indicator turns on
The ERR indicator lights steadily for approx. 15 seconds, and then starts
flashing at a rapid rate (about three times per second).
If the ERR indicator turns off, skip to the section below.

3. Set section 1 of IR-IP DIP switch to ON.
The ERR indicator starts flashing faster (approximately four times a second).
4. Send a ping to the new address to be used by IR-IP. A confirmation should be
received after the third ping: after the confirmation, the flashing will slow
down to approximately twice a second.
