RS-232 Receptacle (RJ-45 Style): The RS-232 Computer Interface is used for computer controlled
factory test, for calibration, for customization, and for remote control/data acquisition.
AC Line Power Receptacle: The AC line input range is 100 - 240 VAC (47 - 63 Hz). AC line voltage
within the specified range has no effect on any dosimeter measurements. The IEC 320/C13 style
receptacle permits worldwide operation by simply changing the line cord.
Triaxial Ion Chamber Input: This input is preferred in semi-permanent setups where the dosimeter is
stationary at the treatment console. The rear triaxial is wired in parallel with front panel input.

3.4 Powering The System

The Model 35040 Therapy Dosimeter may be operated from either line or battery power. The line
receptacle at the rear panel of the Model 35040 Therapy Dosimeter mates with a 3-wire line cord to
provide a connection to line voltage (high, neutral and earth ground).
When powering the Model 35040 Therapy Dosimeter from an
AC line, always use a 3-wire grounding type line cord such as
the one supplied with the dosimeter. In addition, only connect
the Model 35040 Therapy Dosimeter to an AC power outlet
employing a third wire safety ground. Failure to ground the
Model 35040 Therapy Dosimeter may result in personal injury
or death in the event of a short circuit or malfunction.
