Cable Required

RS232 Sampler/Flow Meter to PC Cable Assembly (Cat. No. 1727), 10 ft long, 6-pin connector on one end, 9-pin D connector on the other end (9-pin to 25-pin D type adapter included).

6.1.2 RS232 Programming

Note: Some early generation IBM compatibles may have a serial port that is not capable of communicating reliable at 19,200 baud. If errors develop at high baud rates, try lowering the baud rate one step at a time (on both the sampler and Streamlogg II™, InSight®, or Vision® software) until error free communications is achieved.

1.From the Main Menu, select OPTIONS > ADVANCED OPTIONS >

COMMUNICATIONS SETUP > RS232 SETUP.

2.Select a baud rate for data communications by pressing the CHANGE CHOICE key to cycle through the possible choices; 1200, 2400, 4800, 9600 or 19,200 baud. The higher the baud rate setting, the faster data will transfer. Set the baud rate to the highest setting allowed by the computer. The baud rate must correspond to the baud rate selected in the software. Press ACCEPT.

Note: Long runs of RS232 cable, especially if they are run near large motors or fluorescent lights can cause communication errors and may require a slower baud rate.
