NOTE
When you connected the ACP and PC through a cross cable, but you cannot access the ACP
• Check IP address of the ACP and IP address of the PC.
Ex) If IP address of the ACP is 192.168.1.101 and Net mask is 255.255.255.0, check if the
first three digits of the IP address of the PC is the same as the first three digits of the
IP address of the ACP.
In such case, the IP address of the PC shall start with 192.168.1, and it shall be differ-
ent from the IP address of the ACP. Set as follows, and try again.
- Setting of the ACP
IP address: 192.168.1.112
Gateway address: 192.168.1.1
Subnet Mask: 255.255.255.0
- Setting of the PC
IP address: 192.168.1.113
Gateway address: 192.168.1.1
Subnet Mask: 255.255.255.0
• Check the status of the Ethernet cable (LAN cable).

NOTE
When PC and ACP are connected together in a hub or a switch hub, and you cannot access
the ACP.
• If it is right after changing the IP setting of the ACP, reset the power of the ACP.
• If it is right after connecting LAN cable to the hub or switch, it may take time for the hub or
the switch to recognize the ACP. In such case, it may help to turn off and turn on the
power of the hub or the switch.
• Check the status of the Ethernet cable (LAN cable).
• Check ARP table of the PC to see if the IP address of the ACP correctly corresponds to the
MAC address. If duplicate MAC addresses correspond to one IP address, or if different
address from the MAC address of the PC is output, there may be a host with the same IP
address as the IP address of the ACP. In such case, the IP address of the ACP or the IP
address of the corresponding host shall be changed.
