On and Off positions are marked in white letters on the circuit board nearby the On Off Switch The Main Battery provides main power to the Cyclops 7 Logger 3 4 Connection to Serial Port The Cyclops 7 Logger must be connected to a host computer to use the Cyc7Calibrate and Cyc7Service software It can also communicate with a terminal program such as Hyperterminal PICTURE HERE OF THE SERIAL PORT CABLE CONNECTED TO LOGGER Connect the Cyclops 7 Logger to a host computer by plugging the connection cable into the RS232 connection within the Cyclops 7 Logger Connect the opposite end 9 pin D connector to the host computer s serial port On a PC desktop this is the COM port Some computers may not implement a COM port in which case the serial port must be emulated by using a USB to Serial converter Turner Designs supplies a serial to USB converter in the Cyclops 7 Accessory Kit In addition to the physical connection the host computer may run a terminal program such as Hyperterminal Windows 2000 and XP ship with Hyperterminal located at programs accessories communication Later Windows operating systems do not The Cyclops 7 Logger communicates as shown in the table below Appendix 1 shows how to set Hyperterminal for this protocol and gives other information about communications programs In general Customers should not need to use software besides Cyc7Calibrate to communicate with the Cyclops 7 Logger Baud Rate 9600 bits second
