- Page 2 This warranty does not apply to equipment that has been subjected to misuse or which has been repaired or altered in any way by the user. Spellman High Voltage is responsible only for the cost of material and labor to repair or replace, FOB our factory, products proved to be defective during the warranty period.
- Page 3 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.
- Page 4 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.

- Page 6 200-c488 must be configured to implement the correct data formats for each supply. After removing the top cover of the 200-C488, a six position DIP switch may be seen on the large printed circuit board. Table 2.1 shows the correct setting for each power supply.
- Page 7 The meaning of the serial poll status byte that is read depends on the condition that caused the service request. The power –on mode is true when the 200-C488 is first turned on and before the GPIB controller sends a command to the interface. The overload detect mode is after the GPIB control has sent its first command to the interface.
- Page 8 When the invalid request bit is logic 1, it means that you have issued a command the unit cannot recognize. Normally this bit stays at logic 0. Spellman High Voltage Electronics Corporation One Commerce Park, Valhalla, NY 10595, (914) 686-3600, Fax: (914) 686-2870...
- Page 9 USER COMMANDS The 200-C-488 recognizes a number off commands, in the form of ASCII strings. These commands execute the various programming and monitoring functions enabling the user to control a Spellman Series 20A/210 high voltage power supply. These commands are: ♦...
- Page 10 11,500 volts, the command will be P11.500K. The actual high voltage output will not change after the program command until the 200-C488 receives a device trigger bus command or the ‘G’ command string (see sections 3.1.4 and 3.2.3).
- Page 11 Lxx.xxxK L29.400K limits to 29.4kV The output current limit threshold may also be set. When this value is exceeded the 200-C488 will respond as programmed by the user. This command also requires a strict numerical format. Since it represents output current, the decimal point, may be in a different position than the voltage format. Below are some examples of the current limit command.
- Page 12 3.2.7 SELECTING THE OVERLOAD SERVICE REQUEST RESPONSE (‘N’) Just as the 200-C488 may be made to shut off the output during an overload, it may be may to generate a service request to the GPIB controller. The syntax is: “N {numeric}’...
- Page 13 Since this is an ASCII string it may be printed directly to the CRT or printer. After receiving the ‘T’ command the 200-C488 will return a character string containing the output status (Normal, Tripped or Shutdown) and the voltage and/or current readings in the same numerical format as is used to enter voltage and current values.
