User and Programming Manual – Rev P California InstrumentsNote: The PGUI32 can be run in the absence of a power source. If no AC source isavailable , the PGUI32 can be operated in a simulation mode. The program willdetect these conditions and start up in simulation mode after notifying theoperator. Measurements in this case will be simulated and should not be usedfor any analytical purpose.8.4. RS232C Cable WiringCalifornia Instruments AC power sources require a special RS232C cable to communicatewith a PC. Standard null-modem cables obtained from a computer hardware store mostlikely will not work. For this reason, all California Instruments power sources that operateover RS232C are supplied with a RS232C 9 pin female to 9 pin female cable.If for some reason this cable cannot be located, the following cable diagram shown in Figure8-1 should be used when constructing a serial cable.Figure 8-1: RS232C Cable WiringDB-9 PC DB-9 AC SourcePin123456789Pin123456789Directionoutputinputoutputoutput-input--outputDescriptionreservedReceive data(RxD)Transmit data (TxD)Data Terminal Ready (DTR)Signal GroundData Set Ready (DSR)no connectno connectreservedNote: This cable is not bi-directional so it is important to mark the PC side and theAC source side of this cable. If the cable is connected in reverse, it will notoperate correctly.RP Series October 2005 35 |
