CONNECTIONS & CONTROLS
RECEIVER
S1 Hexadecimal rotary switch. Changes the gain in 1dB steps from 0 dB to 15dB
S2 The left position is used to MUTE the RF output by removing power form the final am-
plifier stage. The right position switches the gain from HI to LO by switching in 0dB or
10dB attenuation.
J1 A ground point for a Digital Volt Meter (DVM) probe
J2 Optical
Input
J3 Optical Input Power test point for a DVM probe. Output is 1 Volt/mW
J4 RF Output, 50Ω or 75Ω
J5 9-Pin DIN connector for use with the OTAPS power supply. Pinout is as follows;
Pin 1 Input DC Voltage (+8 to +24 V
DC
).
Pin 2 Ground
Pin 3 Ground
Pin 4 FAULT. The receiver pulls this low if it detects a fault.
Pin 5 Pulled to +5 Volts through a 90Ω resistor to indicate that the unit is powered.
Pin 6 Not used.
Pin 7 Ground
Pin 8 Ground
Pin 9 Ground
J6 Optional Power input. Diode or’ed with J5-Pin 1. The higher of the two voltages actually
powers the unit.
J7 Status Outputs
Pin 1 Optical Input Level. 1V/mW
Pin 2 Optical Fault. Pulled to ground when a fault occurs. Valid optical range is de-
fined as +3dBm to -15dBm.
Pin 3 Ground
Pin 4 RF Fault. Pulled to ground when a fault occurs.
Pin 5 RF Level. Analog test point.
D1 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.
D2 Power indicator. Green when normal.
D3 Optical Input Level. Red if RF level is too high, Yellow if RF level is too low and Green if
level is within normal limits.
