Sequoia Series 25
3.3.2 Serial Cable Diagram
The cable for the RS-232C interface must be of the “Null Modem” type, straight through. If the controller
or PC only has a 25 pin D sub COM port, a 25 to 9 pin adaptor is required to use the serial cable
supplied with the Sequoia. If none can be found, one can be constructed using the diagram shown
below.
