Hi Ralph,

There is no direct cabling scheme for connecting a RJ45 port on the system to the serial port on the printer until you want to use a port converter of some kind. The two ports have different communication standards.

Hope this helps.

Was it your intention to try and describe an effort to hook up the RS-232C port on the printer to the RJ45 connector on a Network Interface card?

If so, then THAT is flat impossible.

If not, say you were attempting to describe an attempt to hookup the RS-232C port on the printer to a port on an MX72 MUX (which does support RS-232) then you need to post more information and be a bit more clear about what is being hooked to what, including part & model numbers.

We will be happy to help you, however the more info you provide the easier our job is and the more accurate the assistance we provide.

Hello Ralph,

The "serial pinout" on the LaserJet is a 9-pin (DB9) and the interesting pins are 2, 3, and 5.
The only serial RJ45 from the 3000 would be on a Direct Distribution Panel (DDP) on the back of a DTC, and the interesting pins are 1, 3, and 6. To connect the two:

DTC RJ45......Printer DB9
1.............2
3.............3
6.............5

Please note (as Paul said): you CANNOT connect a serial printer's port to a LAN (RJ45), but you CAN connect the printer to a DTC (RJ45)
