Magnum 6K8-Series Industrial Field Switch Installation and User Guide (04/07)
3.2.1 Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using a PM with ST-type fiber
connectors. This procedure applies to ports using a 6K8-Series module, MST-
type port.
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the PM. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting.
Note: One strand of the duplex fiber optic cable is coded using color
bands at regular intervals; you must use the color-coded strand on the
associated ports at each end of the fiber optic segment.
3. Connect the Transmit (TX) port (light colored post) on the Magnum PM to the
Receive (RX) port of the remote device. Begin with the color-coded strand of
the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post on the PM) to the Transmit
(TX) port of the remote device. Use the non-color coded fiber strand for this.
5. The LINK LED on the front of the PM will illuminate when a proper
connection has been established at both ends (and when power is ON in
the unit). If LINK is not lit after cable connection, the normal cause is
improper cable polarity. Swap the fiber cables at the PM connector to
remedy this situation.
3.2.2 Connecting Fiber Optic SC-type
, "Snap-In"
The following procedure applies to installations using a PM with SC-type fiber
connectors, i.e., using 6K-MSC, 6K-SSC single-mode.
While connecting fiber media to SC connectors, simply snap the two square male
connectors into the SC female jacks of the 6KPM module until it clicks and secures.
3.2.3 Connecting Single-Mode
Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port
connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable
(9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx
