DiCon Fiberoptics VX500 Fiberoptic Switch
Connecting to the Interface
The electrical connector on the DiCon VX500 Switch is a male twelve-pin 0.100-inch right-
angle square-pin friction-lock header (Molex part number 22-12-2124). To mate to this con-
nector, use a corresponding female receptacle housing (Molex part number 22-01-3127 or
equivalent) and contacts (Molex part number 08-56-0110 or equivalent). The mating con-
nector can be obtained from Molex (Tel: (708)969-4550) or from DiCon Fiberoptics, Inc.
The maximum length of the control cable is two meters. Use shielded cable for lengths
greater than one meter.

Reading the Status LED
The status LED provides a constant visual indication of the state of the switch. The four
possible states are defined in the following table.
Thermal Considerations
The VX500 generates about 3 watts of heat continuously. The switch may not perform cor-
rectly if it is allowed to overheat (50°C max.). Under some circumstances, a vented air flow
may be necessary in order to keep the housing temperature within range.
