Using the RS-232 Receptacle
The operation of the Logic+ Biological Safety Cabinet (BSC) can be monitored using a
computer connected to the RS232 receptacle located on the top electrical box of the
Logic+. The computer monitors the Logic+’s operation, but cannot control the
operation of the Logic+.
Connection for Computer Interface
Check your computer to see which type of RS232 serial port is provided. Use one of the
two connecting cables listed below:
1.
Computers with a 25-pin D-sub male serial connector should use Connect Cable,
Labconco part number 7537801, to connect a computer to the Logic+.
2.
Computers with a 9-pin D-sub male serial connector should use Connect Cable,
Labconco part number 7537800, to connect a computer to the Logic+.
* Note – If your computer does not have an RS-232 serial port a USB to RS232 adapter
can be purchased at most computer stores, discount stores, etc. to allow the Logic+
cable to connect to a USB port on your computer.
The purpose of the RS232 interface is to send data to a data logging computer to
monitor the state and activity of the Logic+. This data is half duplex data. The data
properties are as follows:
1.
