603xA: Secondary Address
Question: How can you change or view the secondary address in the 6030A, 6031A, 6032A, 6033A, 6035A, or
6038A power supplies?
Answer: These products have been retrofitted with SCPI language capability, in addition to the original or
compatibility mode. Secondary addressing of these products is only available in SCPI mode. These products are
shipped from the factory in the COMPatible Language Mode with their hardware address set to "Adr 5". Secondary
addressing is NOT available in COMPatible mode.
To change the programming language to SCPI Mode send string "SYST:LANGTMSL" using an GPIB controller. In
the SCPI Mode, either by cycling the ac line or by holding in the [ LCL ] front panel button. The display will first
show "Adr 5", the primary address, for 2 seconds, then "SEC xxx" the secondary address until the [ LCL ] button is
released. The primary Address is set using the rear panel address switch. All instruments connected directly to the
GPIB interface must have a unique primary address. With the [ LCL ] button depressed, and the display showing
"SEC xxx", the rotary pulse generator can be used to change the xxx portion from "---" (null) to an integer number
between "0" and "15".
A display of "Adr 5" followed by "SEC ---" designates the the instrument to be a stand alone instrument and must be
talked to by using address 705. A display of "Adr 5" followed by "SEC 0" designates the instrument as the direct
instrument in a possible chain of instruments and must be talked to by using address 70500. (This instrument must be
the instrument connected to the controller via the GPIB cable). In either case ("SEC ---", or "SEC 0"), the display
"Adr 5" is still viewable when the ac power is cycled or when the [ LCL ] button is initially depressed. A display of
"Adr ---", primary address a null, followed by "SEC 1","SEC 2", or "SEC nn" when the ac line is cycled or the [
LCL ] button is depressed is a linked instrument. Instruments where the "SEC nn" is a number = or > 1 are linked
instruments, and can only be talked to by a direct instrument. Linked instruments can never be talked to directly from
the controller.
If a unit is in the SLAVE or LINK mode and you wish to convert it to a MASTER, follow this procedure:
Set the GPIB address to a reserved address "31".
Turn the unit off, then turn it on again.
Set the address to "5" or any valid address number.
Cycle the power again and the unit will now be set as a MASTER.
NOTE: The choice of programming language is stored in the instrument's nonvolatile ROM and remains the
language of choice until deliberately changed by the user. Reference the 603xA family Operating Manual, p/n 5959-
3342. Errors reported as "8" or "-113" are characteristic of using a programming syntax which is inconsistent with
the product's setting/expectations.
