CONNECTIONS & CONTROLS
TRANSMITTER
Refer to Figure 1 for clarification of terminology
S1 Hexadecimal rotary switch. Changes the gain in 1dB steps from 0 dB to 15dB. The “0”
setting corresponds to 0dB gain. The “F” setting corresponds to 15dB gain. See Table 2 for
more details.
S2 The bottom position switches the gain from HI to LO by switching in 0dB or 10dB at-
tenuation. See Table 2 for more details.
J1 A ground point for a Digital Volt Meter (DVM) probe
J2 Optical
Output
J3 Laser Power test point for a DVM probe. Output is 1 Volt/mW
J4 RF Input, 50 Ohms or 75 Ohms (Located on back of the unit.)
D1 Laser Power. Green when laser output is OK. Dark when laser fails.
D2 RF Level. Red if RF level is too high, Yellow if RF level is too low and Green if RF level is
within normal limits.
D3 Laser Temperature (DWDM Laser Models Only). Green indicates good, red bad.

RECEIVER
Refer to Figure 3 for clarification of terminology
S1 Hexadecimal rotary switch. Changes the gain in 1dB steps from 0 dB to 15dB
S2 The top position is used to MUTE the RF output by removing power form the final am-
plifier stage. The bottom position switches the gain from HI to LO by switching in 0dB or
10dB attenuation.
