How To Connect to a Type PDR Series Readout
This section provides information on how to wire a Type PDR Series readout to a Type 7xxC
transducer with either a Type “D” or Bendix connector.
Caution
DO NOT use the -15 VDC output of the Type PDR readout to power
the 7xxC/800B Series transducer. When the -15 VDC signal of the
PDR is connected to the power return of the transducer, a short
between the -15 VDC of the transducer and the A GND of the PDR
occurs. The PDR readout will blank out. Either unit may be
damaged.
Note
This information replaces the color code information found in the PDR
manuals.
Type “D” Connector (either 9-pin or 15-pin High Density)
The correct cable to use for the 9 pin Type “D” connector is CB700-2; the cable for 15-pin High
Density connector is CB700-6. The correct cable has the mating Type “D” connector on the
transducer end and flying leads on the PDR end. Table 16 lists the pin assignments for the
various colored wires on the flying leads end of the cable.
