1 port among 5 ports is available for cascade changeover.
1 port among 8 ports is available for cascade changeover.
The allowable maximum wiring length is 100m in connection. Also, twist pair cable is subject to a
standard for category sorting stipulated by EIA/TIA. Twist pair cable in accordance with category
3 and 5 is used for Ethernet, but one in accordance with category 5 is recommended.
Over-the-counter LAN cable is in accordance with category 5 and either 10BASE-T or
100BASE-Tx is available.
This cable is used for connection to optical cable, of which adaptable category is 5 and of which
form is the same as for 10BASE-Tx.
Remarks
Basically, the address range of G-50A is fixed to "000" at the factory.
M-NET remote control includes ME remote control, compact
remote control, and Lossnay remote control to connect to M-NET
transmission line.
When MA remote control is used, address setting is not
necessary.
G-50A can also be used within the address range shown at the
