RS232-GPIB Converter
An optional user-supplied RS232-to-IEEE 488 converter can be used with the RS232
connector on the RM meter to access an IEEE 488 parallel interface. The converter, supplied
with the appropriate RS232 cable, is attached to the RS232 connector on the rear panel.
The converter is set up and tested as described in Table 10 and Table 11. To avoid conflict
with other GPIB devices, the GPIB address can be changed.
