Remark: 1. For the PC, parameter Host Address can have values between 1 and 255 and this
value must be different from parameter Axis ID for IDMs in the network. For example, if the Host
Address is set to 255, then none of the IDMs in the network can have Axis ID set to 255.
2.The PC can be placed in any position in the network.
