Page 6: Introduction
FOM LINE DRIVER—ST AND S M 2. Introduction With the FOM Line Driver, you can use an RS-232, RS-485, or 20-mA digital current-loop device in a multi-drop half-duplex or point-to-point full-duplex environment using fiber optics as the transmission media. The Driver is user-configurable in any of these operating modes: network mode, master/slave mode, or full-duplex point-to-point configuration. -
Page 7: Configurations
FOM LINE DRIVER—ST AND S M 3. Configurations There are three operating modes you can choose from: network mode, master/slave mode, or point-to- point configuration. In network mode, all of the units are configured. If you want one Line Driver configured as a master and the others as slaves, you need to be in master/slave mode. -
Page 8: Master/Slave Mode
FOM LINE DRIVER—ST AND S M 3.2 Master/Slave Mode When the master sends data to the transmitter (TX) of the RS-232 DB9, the 20-mA current loop, or the RS-485 terminal block, the data is passed through to the master’s B optical port. From there, it is daisychained to each slave’s B optical RX. -

FOM LINE DRIVER—ST AND S M 6. Troubleshooting 6.1 Application Problems If you’re having a problem with your application, reread the manual. Make sure you’ve selected the appropriate switches for the interface you chose. If your Line Driver is still not working properly, fill out an application diagram (found on pages 19, 21, and 23). - Page 19 FOM LINE DRIVER—ST AND S M Application Diagram forms are found on pages 19, 21, and 23. You may be asked to fax your diagram to the Technical Support department. Use scissors to remove the page.
