Turn on the GP485. Wait approx. 5 seconds until the Power/Ready led illuminates so the self test can be
completed and the unit is ready for operation. Change the GP485 communication configuration as
follows:

The functions description in Table 5-5 explains that the GP485 records specific status and error
information. This means that it stores that information in it’s memory so that it is available when
requested by the user. The functions description also include an explanation on return of information to
the user from the GP485. This is accomplished by information sent to the user from the GP485 over the
GPIB.
The GP485 continuously monitors the serial port for transmission errors. If an error is encountered in
the serial data, the GP485 records the error. The GP485 can be programmed to ignore serial port errors
using the
4.5
The following procedure ensures that the GP485 controller is operational and may be used as a basic
incoming inspection check.
Check that the rear panel RS485 cable is connected as shown in Fig. 3-3. Connect the GPIB cable
between the GP485 and the host computer. (Refer to Fig. 3-4 for GPIB connector description). Connect
the GP485 to an AC source as described in paragraph 3.6.
- The program examples within the functions description are written in Microsoft QuickBASIC Version
4.5, using National Instruments NI-488.2 function calls. Although the examples in this manual are
written in BASIC. The GP485 can be programmed using any language that has access to a GPIB port.
- The following NI-488.2 function call addresses the GP485 to listen and sends it the programming
message
WRT$=”SPSET”+CHR$(13)
CALL IBWRT(GP485% , WRT$)
If not using the National Instruments NI-488.2 software, be sure your program properly addresses the
GP485 and the serial device when writing to and reading from them.
- In the function syntax descriptions, arguments shown in square brackets ( [ ] ) are optional. Do not
enter the brackets as part of the argument.
- Function name abbreviations can be used, which include as many characters as necessary to
distinguish them from other functions. The abbreviated forms are indicated by
description of each function.
