3.4 Connection board
The connectors on the Connection board are grouped in relation to products.
Each connector has been given a unique name and designator in order to clearly identify the connector. Also
wherethewiresaremountedintoterminalstrips,eachconnectionhasbeennamed.Therstdigitofadesigna-
tor, is a consecutive number, and the second digit is a digit only used for connections belonging to that group.
Everydesignatorstartswitha„J“,toindicatethatthisisatypeofconnector.Forexample,therstconnector
for VHF connection carries the designator „J20“, the second connector „J21“ and so on.
Consoles with two connection boards, the primary equipment connects to the left connection board. The
duplication equipment connects to the right connection board. This means that for example in communicati-
ons systems with two VHF radios, the primary VHF is the one located in the console and connects to the left
connection board. The duplication VHF will, if connected through the console connect to the right hand side
connection board.
