RJ-45, DB-25 PinsNotesIn order to expand the functionality of the serial interface, the MAXserver 1600/1608modular cabling allows you to connect different signals to pin 7 of the MAXserver.(This pin is an input to the MAXserver.) When a DCE device is connected to aMAXserver serial port, the device's DCD output is connected to pin 7. In this case, thesignal at pin 7 is referred to as DCD.When a DTE device is connected to a MAXserver serial port, the device's DTR output isconnected to pin 7 of the MAXserver. In this case, the signal at pin 7 is referred to asDSR. (This cabling scheme also provides DECconnect compatibility, sinceDECconnect does not support the DCD signal.)0590 51
