Setup
The Python II system consists of:
• One Python II TX Transmitter
• One Python II RX Receiver
or
• Two Python II 8x8 Transceivers
• External power supplies (AC/DC adapters)
• Rack mount adapter kits (ears)
After unpacking, inspect the units for mechanical damage, and all electrical
connectors for bent or damaged pins and latches. Report any damage to the
carrier and to Telecast Fiber Systems, Inc.
Leave the protective caps on the optical connectors until it is time to attach the
fiber to the units. Replace the caps whenever the fiber is disconnected.
Rack Mounting
Units feature integrated rack ears that are a part of the frame.
Place each unit in its intended location before attaching any cables or fibers to
prevent accidental damage to the cables or their connectors.
Line Power
Any power supply used with the Python II must provide a minimum of 1.5 amps,
continuous, at 12 to 24 VDC. Two 4-pin DC power inputs are provided for
redundancy.
There is no internal backup battery of any sort in the Python II.
Power input is through a 4-pin XLR connector located on the left side of the rear
panel; see Table 2 for pin-out and Figure 2 for location. Be sure that AC outlets
are within reach of their 6-foot power cords.
