7310 Installation and User’s Guide
Installation
3.1 Setting Up the Transmitter
1. Place the 7310T Transmitter in 7180M Chassis. The operating base plate
temperature must be between -10
°
C to +55
°
C.
2. Apply AC power to the chassis. The Laser LED should be lit.
3. Using an optical power meter, measure the optical power. Insert the
meter’s cable into the Transmitter’s optical connector. Power levels should
be between 0.4 - 1.0 mW.
Alternatively, use a DVM to measure the voltage at:
•
pins J13-P17 through J13-P24 for the slot being measured (Refer to
Table 6
on page 35 for details regarding J13 pinouts) (7100M
Rackmount)
•
at pin #6 of the 9 pin connector (standalone)
The power level should be -4.5
±
0.3 VDC.
4. On the rear panel, connect the coax cable to the RF Input Connector. The
RF LED should be lit.
5. On the rear panel, connect the fiberoptic cable to the Optical Connector.
6. Adjust the Gain Control Potentiometer to give the desired output power.
Using a small screw driver, turn the potentiometer (located on the front
panel) to increase or decrease the gain.
•
To
increase
the gain, turn the gain control clockwise.
•
To
decrease
the gain, turn the gain control counterclockwise.
For more information refer to Aligning the Fiberoptic Cable on page 25.
Note
The potentiometer is 10 turns potentiometer.
Note
If either LED is not lit, refer to Trouble Shooting on page 37.
CAUTION
When monitoring the voltage outputs use a high resistance DVM only.
