FEATURES AND OPERATION
2-5
Part No. 001-4090-101/102
2.3.2 POWER
The Integra-H power requires a regulated power source of 13.3 VDC nominal (10 - 16 VDC
max.) negative ground with a minimum 2.0 A rating. An internal surface-mount 3A modem fuse (not
field-replaceable) and a crowbar diode protect the main RF power components from reverse polarity.
Application of more than 16 VDC will damage the unit and is not covered by the warranty.
WARNING: Do not exceed 16Vdc.
2.3.3 POWER / ANALOG CONNECTOR
The 4-pin power / analog connector pin out is shown in Figure 2-5.
Figure 2-5 Power / Analog Connector
Note: The color of the power cable wires are shown in parenthesis. If the analog connections are
not used the green and white wires should be cut back and/or taped to prevent contact. (See Table 1-1 for
power cable part number)
2.3.4 ANALOG CONNECTIONS
The two analog connections can be programmed as inputs (monitoring) or as outputs.
2.3.4.1 Analog Inputs
Voltage inputs are scaled between 0 and 10 VDC and have a resolution of eight bits (1 part
in 256). Monitoring inputs, measured in tenths of a volt, are referenced to chassis ground.
The absolute maximum input voltage should not exceed 20 VDC. These inputs are reverse-
voltage protected. Integra-H allows reading the analog values, locally or remotely, using the
Offline Diagnostics function of the Radio Diagnostics Software (RDS) program. To use an
analog connection as input, ensure that the required input box is checked in the RSS program
under Settings / Analog Connector.
