Cause
The LAN cable connector is
disconnected or the
connection is incorrect.
The IP address and subnet
mask settings are incorrect.
The gateway address setting

LAN communication
equipment (HUB or router)
has failed.
LAN cable disconnected or
contact failure.
Check procedure and remedy
Enter the following in the command prompt on the PC, press the [Enter]
key, and check the response.
Ping [IP address of AE-200/AE-50/EW-50]
E.g.: ping 192.168.1.1 (IP address of PC: 192.168.1.101)
If communication was successful, the reply is as follows.
Reply from 192.168.1.1: bytes=32 time=1 ms TTL=64
If the LAN cable is not connected or the IP address setting is incorrect,
the reply is as follows.
Request timed out.
If the subnet mask, gateway, or other network setting is incorrect, the
reply is as follows.
Reply from 192.168.1.250: Destination host unreachable.
Insert the connector of the LAN cable properly into the LAN port at the
back of the AE-200/AE-50/EW-50.
Furthermore, old types of HUBs have two port types, one for a terminal
connection and one for a HUB connection, so check whether or not the
LAN cables of the AE-200/AE-50/EW-50 and PC for the browser are
connected to ports for terminal connections.
Unless other specified, set the IP address as follows.
AE-200:
AE-50:
EW-50 (standalone):
EW-50 (expansion controller):
PC for browser:
PC for integrated centralized control software TG-2000A: 192.168.1.150
Set the subnet mask to 255.255.255.0.
If a router is connected to the network, the gateway address needs to be
set on the AE-200/AE-50/EW-50.
Set the IP address of the router to which the AE-200/AE-50/EW-50 will be
connected as the gateway address.
If a connection error reply is returned for the ping command even after
checking the various settings above, the cause is probably a failure of the
LAN communication equipment (HUB or router) or a defect of the LAN
cable itself.
Replace the HUB or other communication equipment or the LAN cable
and then perform a connection check.
