J-CC Data Cable Operating Instructions
User's manual for OPTO-RS cable connections General The OPTO-RS cable enables a direct connection with most of the Käfer measuring instruments to a personal computer, a dedicated printer or to a Käfer display unit. It is not only a cable, but an interface which converts the data output of the instrument to a compatible RS232 signal. The periphery instrument connection must be able to supply power to the OPTO-RS plug.
Two different types of OPTO-RS plug connections are available: Simplex and Duplex Simplex cable First generation of OPTO-RS cable connection, designed for instruments which were not able to receive RS232 commands. Data requests are made by LED status change (e.g. by turning off the DTR signal line for a minimum of 110ms). The OPTO-RS simplex cable can also be used with duplex instruments, however remote commands will be ignored.
List of remote commands This list shows the main remote commands applied using DUPLEX instruments.
Visual Basic The communication control (MsComm) of VisualBasic must be applied : Port opening ' Use COM1. Comm1.CommPort = 1 ' 4800 baud, even parity, 7 data, and 2 stop bit. Comm1.Settings = "4800,E,7,2" ' Open the port. Comm1.PortOpen = True Power supply setting ' Simplex Cable' Form1.MSComm1.DTREnable = True Form1.MSComm1.RTSEnable = True ' Duplex Cable' Form1.MSComm1.DTREnable = True Data request Form1.MSComm1.RTSEnable = False ' Simplex Cable' MSComm1.DTREnable = False Timer1.
