nGENERAL
The Optical ESB Bus Repeater Module converts the ESB bus to an optical signal and transmits it. The ESB bus
transmission distance can be extended within the range of up to 4 km by connecting the ANT421 Optical ESB Bus
Repeater Master Module and ANT522 Optical ESB Bus Repeater Slave Module with an optical ber cable.
These modules can replace existing ER bus and RIO bus to the optical ESB bus by utilizing the existing multimode
ber cables.
lANT421 Optical ESB Bus Repeater Master Module for 4 km
This module can be installed in the Field Control Unit, FIO Node Unit (ESB Bus Node Unit,Optical ESB Bus Node
Unit) and Optical ESB Bus Repeater Unit.
To connect ANT421 to ESB Bus, ANT401 requires the ESB Bus Adapter “Connector unit for ESB Bus” (A2EE2A-N).
To terminate ESB Bus at ANT421, ANT421 requires the ESB Bus Adapter “Connector unit with terminator for ESB
Bus” (A2EE2A-T). ESB Bus Adapter A2EE2A should be ordered separately.
lANT522 Optical ESB Bus Repeater Slave Module for 4 km
ANT522 is installed as standard in Optical ESB Bus Node Unit as a slave module of the optical ESB bus. It can also
be installed in Optical ESB Bus Repeater Unit.
To connect ANT522 to ESB Bus, ANT522 requires the ESB Bus Adapter “Connector unit for ESB Bus” (A2EE3A-N).
To terminate ESB Bus at ANT522, ANT522 requires the ESB Bus Adapter “Connector unit with terminator for ESB
Bus” (A2EE3A-T).
To monitor the temperatures and fans in the cabinet, specify “With HKU interface” (A2EE3A-H).
The ESB Bus Adapter A2EE3A should be ordered separately.
lInstallation Position
The following table shows the units and numbers of slots in which ANT421 and ANT522 can be installed.
For the installation positions corresponding to the slot numbers, see “FIO System Overview” (GS 33J60A10-01EN),
“N-IO System Overview” (GS 33J62A10-01EN), and “Field Control Unit, Cabinet Utility Kit (for RIO System Upgrade)”
(GS 33J64E10-01EN).
