S232 communications port allows bi directional data transfer via a three conductor cable consisting of signal ground receive input and transmit output It is recommended that less than fifty feet of cable be used between the computer and this instrument Note that multiple instruments cannot be tied to the same port in this configuration The RS232 port is optically isolated to eliminate ground loop problems Below is a pinout diagram for the serial port of the BB701 as well as the pinout for a 9 pin PC serial port Use a straight DB9 female to DB9 male connector cable to connect your computer to the BB701 The cable should be attached only when the computer and BB701 are off Only parameters in the parameter list should be modified or queried via the serial port Other parameters can be viewed or queried from the controller directly It is highly recommended that baud rate for the controller be modified on the controller directly Note that both the BB701 and the computer must be communicating with the same serial communications parameters to establish a working communication link The serial communications feature can be tested using any standard terminal emulation package Note that this controller does not time out waiting for the next character to be transmitted Be sure not to use the XON XOFF or hardware handshaking Lastly it should be noted that following a complete transmission to the BB701 a response is sent back If the messag
