Applications The fiberoptic port of the ABB REL55x/56x , Line Differential Protection Terminals, is directly connected to the fiberoptic port of 21-180. The 21-180 Codir- port is then connected to a 2048kbps G.703 E1 multiplexer.

Page 9: Serial Number
Installation. Serial number. The products serial number is the best way for Fibersystem to identify the product. If the serial number is not noted on your delivery notes, please add the serial number to your own product documentation. This will be useful at future contact with Fibersystem. - Page 10 Mounting Before mounting check if 21-180 must be configured internally. See later in this chapter under section “Signal ground - Protective earth/ground”. The products can be used stand alone, rack mounted or attached with screws to wall or similar. The rack brackets have two alternative places on each side of the unit and the brackets can be rotated for alternative positions.

“Soft”. Signal ground is connected to PE with a resistor, (100kOhm), in parallel with a condensator, (100nF). A direct connection between Signal ground and PE can be strapped. To do this the 21-180 must then be opened. Disconnect power. Four screws at the backpanel shall be removed. Puch top lid towards backpanel. - Page 13 To connect Signal ground and Protective ground directly connect the terminals of P2 with strap.

Page 14: Normal Use
Configuration Normal use Normally no configuration is needed! When two 21-180 are connected back-to-back, (G.703 Codir ports connected to each other), one of the 21-180 should be set to “Internal Clock”. Config rotary switch Configuration switch The rotary switch has 16 positions, (HEX-switch). -
Page 15: External Clock
Internal clock – “Master mode” When HEX-switch is on position 2, the clock used is generated by an internal clock. This is for example used when two 21-180 are directly connected to each other with galvanic cables. Only one 21-180 shall have this configuration. -
Page 16: Power On
Start and usage. Power on. Connect the power cord to the 21-180 and then connect to a power supply with PE, (Protective Earth/ground connection). The “LO”-LED shall be lit green. If not, try to cross-connect the fibers at one end of the link. - Page 17 1 , 2 , 4 , 8 Yellow LEDs. Marks the position of the Config switch. The four LEDs forms a binary value, lit LEDs, corresponding to the 16 positions of the Config switch. Only position 0, 1 and 2 of the configuration switch are used. LEDs 4 and 8 shall always be “black”.
