SECTION II GENERAL DESCRIPTION
CAUTION-
THE UNIT BEING CONTROLLED BY THE 200-C488 CAN STORE
HAZARDOUS VOLTAGE. COMPLETELY DISCHARGE HIGH VOLTAGE AT
REAR PANEL GROUND TERMINAL BEFORE ATTEMPTING REMOVAL OF
THE HIGH VOLTAGE CABLE.
2.1
INSTALLATION
The Model 200-C488 IEEE 488 interface can amount in a standard 19” rack.
2.2
INPUT POWER
Input AC line voltage required is 115/230 Vac + 10%, 50 – 60 Hz, single phase. The LINE VOLTAGE
selector switch on the rear panel selects either 115Vac operation.
2.3
PROGRAM CONTROL SWITCH
Before the Series 205A/210 may be used in a GPIB system, the power supply must be configured by setting
the power supply’s rear panel REMOTE/LOCAL control switch in the remote position.
2.4
GPIB ADRESS SWITCH
Located on the rear panel of the 200-C488 is an eight-position DIP switch. Every instrument on a GPIB
must have am unique bus address in the range 0 to 30, inclusive. The address is set with five switches A4
through A0, A4 the most significant bit and A0 the least significant bit. Bits A5 and A7 of the address
switch must remain at the logic zero state. Bit A6 control whether the 200-C488 will terminate character
strings with or without a carriage return and a linefeed. Figure 2.1 shows the switch orientation and bit
designations.
The GPIB address switch is only read on power- on. Therefore, when the address is to be changed, the unit
must be turned off and then back on.
