SCOPE OF MANUAL
This manual is provided to assist the user in the installation and operation of the Spellman Model 200-C488
IEEE-488 interface for the Spellman Series 205A/210 high voltage power supplies. For the protection of
personnel and equipment, it is essential that this manual be thoroughly read prior to the installation and
application of power.
1.1
PURPOSE OF EQUIPMENT
The model 200-C488 greatly enhances the versatility of the Series205A/210 high voltage power supplies.
IEEE-488 controllable devices are now found in many different fields, such as engineering and science,
information processing, medicine, industrial process control as well as research and development.
1.2
DESCRIPTION
The 200-C488 is an interface that allows a GPIB controller to program and monitor a Series 205A/210 high
voltage power supply. In addition to duplicating the front panel operation, the 200-C488 provides the user
with a number of additional functions such as programmable overload detection and response. The GPIB
controller may send commands to the interface that programs the output and set other user programmable
parameters, and read back output meter readings and status information.
The 200-C488 is a single 19inch rack mountable unit that is 3-1/2 inches high. It is AC powered (115/230
Vac switch selectable) and connects to the high voltage power supply via a single seven-conductor cable.
