Connecting The Lan Cable; Confirming The Lan Transmission Delay Time - Mitsubishi Electric AE-200A Installation Manual

6-3. Connecting the LAN cable

Connect the LAN cable to the LAN1 port on the AE-200/AE-50. (The LAN2 port is exclusively used for BACnet
function.)
The LAN cable is not supplied. Use a category 5 or above straight LAN cable.
Use a switching HUB compatible with 100 BASE.
The maximum distance between the switching HUB and AE-200/AE-50/EW-50 is 100 m (328 ft).
The recommended number of connected devices such as gateway, router, layer 3 switch, or HUB between the
AE-200/AE-50/EW-50 is four or less. (Transmission round-trip delay time must not exceed one second. If the transmission
delay time is long, a communication error may be detected. Check the transmission delay time, referring to section 6-4.)

for BACnet )
Note
LAN must be installed before the unit installation. Route the LAN cable to the AE-200/AE-50 in the same way as the M-NET
transmission cables.
When connecting the AE-200/AE-50 to an existing LAN, consult the system administrator to decide the IP address. Change
the IP address setting before connecting the LAN cable to the LAN1 port.
To prevent unauthorized access, always use a security device such as a VPN router when connecting the AE-200/AE-50 to
the Internet.

6-4. Confirming the LAN transmission delay time

Connect a monitoring PC to a device such as HUB that is connected to the AE-200. Send a command from the PC
to the AE-50, and receive the response from the AE-50. Check the time between sending and receiving on the PC
display.
