4.2 CONTINUED:
IC/U18A (Over Voltage Comparator) and IC/U17A & U18 (Over Current
Comparator) shut the High Voltage down in the event of an over-voltage or over-
current condition. A fault signal is also sent to the Microprocessor.
IC/U19 is the DC-DC converter that converts the 24VDC to +/-15VDC for the
low voltage signal processing electronics.
Power Supply A1 on the Power/Control Assy. provides the +24VDC for all
electronic and microprocessor circuitry.
4.3 OPALRAD GENERATOR COMMUNICATIONS
The RS-232 Serial Link allows a 3
rd
party application to control the Generator.
Generator settings such as kVp, mAs can be set by the 3
rd
party application.
The complete protocol is available from Source-Ray Inc. upon request.
The following applications have been validated to operate with the PXS-710D:

rd
Party Control Software
The Serial hardware in the PXS-710D generator uses a 2.5KV Optically Isolated
EIA/TIA-232E Compatible 3-wire interface. (Ref Figure 3.1 Item 6) This interface
Operates at 19200 BAUD, 8N1. The Pin assignments are listed in Table 4.2
