3.5 Using a PC to Control Your DC1000(s) with an IEEE-488 LCR Meter (Not a Voltech at Series Product)
To use your PC to control your DC1000s, and an LCR meter with IEEE-488 communications capability, follow the setup in Fig.8.
Connect your computer's RS232 port to the RS232 IN port of the first DC1000 in your chain ('DC1000 # 1'), using a 9-way male to 9-way female null modem cable (see 'Accessories' section of this user manual).
When using an LCR meter without RS232 communications capability, the PC you are using must have both an RS232 port (to control the DC1000s) and an IEEE-488 port (to control the LCR meter directly). Connect the PC directly to the IEEE port of the LCR meter, as illustrated in Fig. 8.
NOTE: See the RS232 communications section for information on USB to RS232 converters.
