Connecting The Lan Cable; Confirming The Lan Transmission Delay Time - Mitsubishi Electric TW-50A Installation And Instruction Manual

6-3. Connecting the LAN cable

To prevent unauthorized access, always use a security device such as a VPN router when
connecting to the Internet.
Connect the LAN cable to the LAN1 port on the TW-50. (The LAN2 port is exclusively used for BACnet
● 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 TE-200/TE-50/TW-50 is 100 m (328 ft).
● The recommended number of connected devices such as gateway, router, layer 3 switch, or HUB between the
TE-200/TE-50/TW-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.)
Note
● LAN must be installed before the unit installation. Route the LAN cable to the TW-50 in the same way as the M-NET
transmission cables.
● When connecting the TW-50 to an existing LAN, consult the system administrator to decide the IP address.

6-4. Confirming the LAN transmission delay time

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