Overview
The BF1E1 Module can be configured individually to NT (Network Termination) or TE (Terminal equipment) mode. The default Pin-Out of this module is always TE mode with used PINS 1,2,4,5. If you want to use NT-mode you may need a “cross cable” which is optional available (BFE1Cross). Line termination (120 ohms) is selectable by DIP switches on the module.
