To use your PC to control your DC1000s, and an LCR meter with RS232 communications capability, follow the setup in Fig.7.

Fig.7
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 with RS232 communications capability, connect the RS232 port of the LCR meter to the RS232 OUT port of the last DC1000 '(DC1000 # 2' in the Fig. 7) in your chain, using a null modem cable (see the Accessories section of this user manual for details on a null modem cable available from Voltech, but please note, that the type of cable required will depend on the type of RS232 connector on your LCR meter. See the RS232 Communications - Pinning section of this user manual for details if a custom cable is required).
NOTE: See the RS232 communications section for information on USB to RS232 converters.
