(4) 12 VDC power receiving terminal board (+12 VDC 1 A maximum)
The EN711 and EN721 (10BASE5) require a separate external power supply of 12
VDC for AUI transceivers.
The external power to be supplied to the AUI transceivers is received at this terminal
board. The terminal board (M3 screw) is the 3P type.
Each AUI transceiver consumes 0.5 A maximum, so a power supply capable of
supplying 1 A or more is necessary in using the EN721.
Be sure to use a separate power supply for each EN7 module.
Note 1: The modules are protected with a fuse inside.
