A.1.4. Input Bus An Input Bus is an internal input channel, working independently of the physical inputs. Any physical input may be mixed together to one Input Bus. There are eight Input Busses in the HDLM 8. A.1.5. Output An Output is an output channel, which is fixed to its dedicated physical analog output. -
