Appendix IV 7100M Chassis
10.2 Installation
The following section details the steps in the installation process which
differ from units installed in the 7180M Chassis. All other steps are the
same.
CAUTION
By default, a 7000 IFL installed in a 7100M is set to 230V. To change the
voltage to 115V, refer to page 71, Changing the VAC.
Observe all warnings and cautions mentioned at the beginning of this manual
(page 11). If after set-up you experience problems, refer to Trouble
Shooting, page 38.
10.2.1 Setting up the Transmitter
1. Place the 7310T in the 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.
•

•
at pin #6 of the 9 pin connector (standalone)
The voltage level should be -4.5 ± 0.3VDC.
4. On the rear panel, connect the coax cable to the RF Input
Connector. The Laser 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.
