No Unit naming Description

In/out RF Port

TX RX

1 VHF+UHF Dual Band 1 Port 1 Port

3) Main Central Processor Unit (MCPU)

MCPU can inquire and control state of modules that are installed in BIU.

This unit can inquire and control state of four ODUs in total. Through communication, it also can

inquire and control ROU that is connected with lower parts.

In addition, the unit has RS-232C port for serial communication so that it can inquire and control

state of devices through PC. On the front panel, it has communication LED indicator to check

communication state with ROU. It also has ALM LED indicator to show whether a device gets

faulty.

For access to upper network, it has a port to insert Ethernet port and GSM modem in it.

[INSTRUCTION] The equipment and accessories including inner lithium battery are to be disposed of safely after the life span of them and national regulation must be observed. Do not attempt to replace the lithium battery unless service personnel confirmation has first been obtained, to avoid any risk of explosion. 4) Main Power Supply Unit (MPSU) MPSU receives -48V of input and outputs +6V and +9V of DC power.

4.2 ODU (Optic distribution Unit) ODU receives TX RF signals from upper BIU and converts them into optical signals. The optical signals are sent to ROU through optical cables. This unit converts optical signals from ROU into RF signals and sends the converted signals to BIU. For each shelf of the ODU, up to two DOUs (Donor Optic Unit) can be installed in it. One DOU is supported with four optical ports. Therefore, one ODU can be connected with eight ROUs. Up to four ODUs can be connected with BIU.

2) 2Way Divider (2W) 2W is equipped with two 2-way splitters in a one-module form and the splitters work for TX/RX signals, respectively. Designed in broadband type, the divider combines and divides 2GHz or higher of signals from FSK modem signals.

As seen in the figure below, connect the coaxial cable for TX and another coaxial cable for RX with corresponding ports at the rear of BIU. For power supply and communication, connect 15Pin D-Sub Connector cable with a corresponding port. 4.3 OEU (Optic Expansion Unit) OEU is mainly used to remotely deliver signals for Campus clusters. At the upper part, this unit combines with ODU and receives TX optical signals to convert them into RF signals.

This unit communicates with upper BIU while communicating with lower ROU. It also acts as communication bridge between BIU and ROU. In addition, the unit has RS-232C port for serial communication, which enables inquiry and control of devices thorugh PC. At the front panel, communication LED indicator indicates communication state with upper BIU and lower ROU.
