1747-ASB Communication interface module

　The optical twin pair cable is installed between two optical modems. One of the two fibers in the cable shall be connected to the TX optical connector on the first optical modem and the RX connector on the second optical modem. The other fiber cable shall be connected in the opposite way, in the RX connector on the first optical modem and TX optical connector on the second optical modem.The modem TC514 is connected to the dual fiber cable of the Advant Fieldbus 100 via the lower (transmitter) and upper (receiver) optical ST connectors.It is recommended that optical connectors be screwed in place with the fingers as the threads on the connectors can be easily damaged if tools are used.

Sufficient space

   should remain beneath the modem to permit a certain minimum bending radius of the cable (R in the figure above). This radius depends on the cable type and is normally 100 mm for apparatus cable and cable for indoor industrial environments. For underground and submarine cable, a radius equal to or greater than 200 mm ( 8”) is normally required. The manufacturer of the cable should be contacted in the event of uncertainty. Contact the optical cable manufacturer about info how to handle the optical cable during installation. The installation of optical connectors on the cable is a precision work which should be performed by specialists. The cable supplier can usually recommend such experts.The optical connectors are of the ST type

Starting an Advant Controller 70 

  When the network has been installed, the Advant Controller 70 (PM810) can be started. Initial Start-up When an Advant Controller 70 communication interface is started, its CDPs are be configured. As the communication interface can not be a Bus Administrator, its CDPs are configured on the Bus Administrator which currently is master. This is performed when the Advant Controller 70 is started and connected to the bus or when a Bus Administrator configured as master has started. At start up all LEDs on the Advant Controller 70 front are lit for about a second during the hardware init. The station is running when the R (RUN) indicator is lit
