EtherLite RJ-45 to DB-25M DCE Modtap Adapter

Modtap - RJ-45f (EtherLite) to DB-25m DCE

The wiring diagram for an RJ-45 8-pin to DB-25 DCE modtap is shown in Table 1.

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.
