EtherLite RJ-45 8-pin to DB-25M DCE modtap adapter
The table shows the wiring diagram for an RJ-45 8-pin to DB-25M DCE
modtap adapter. This adapter is used to connect a terminal/printer to an
EtherLite port, and is available from Digi by ordering part number
76000451.

NOTES:
• This cable utilizes the RTS/CTS signals of the terminal/printer for hardware flow
control.
• Since null-modem swapping is done within the modtap, a straight-through RJ45
cable is used between EtherLite and modtap adapter.
• EIA-232 cables cannot exceed 2500pF.
