DTR / DSR Forced Active (JP8 thru JP12)

DTR is tied to DSR on each of the Sub-Channel ports. If the device connected does not supply a DTR but requires DSR (DTE) or does not supply DSR but requires DTR (DCE), installing the forced DTR/DSR jumper (JP8-JP12) for the appropriate Sub-Channel will solve this problem. The line is forced to +8V via an 820W resistor, providing isolation to any driver that might be on the interface.
