Connecting an rp3410 to Console switch

[Robin King_1]

I'm attempting to attach a couple of new rp3410 servers to our Lantronix console switch. The connections are normally Straight through RJ-45 to RJ-45 connections, but the rp3410 has the DB-9 interface for the console. So I need to sort a RJ45-to-DB9 adapter.

I've found some documentation that suggests the pin-outs for this sort of adapter, but it doesn't make a 100% sense.

Could someone point me in the direction of something that will tell me in layman's terms how to configure the pins on this adapter. I've never done this before.

Thanks

Hi,

look at serial cables:

Is this DCE or DTE?

I'm also not too sure how I'm meant to connect 2 wires from the RJ-45 into 1 Pin on the DB9??

Hi,

In my opinion DTE - this is null modem cable

Hi Robin,
if you don't have correct the RJ45-DB9 adapter, you can prepare yourself such adapter.

On DB9 side of cable you need only 3 wires connected:
2 - Receive Data
3 - Transmit Data
5 - Signal Ground

You need to go to your Lantronix console switch documentation, to see how to connect these wires on RJ45 side.

If you need connect two pins on RJ45 to one pin on DB9, this is ease. Two wires must be joined on DB9 connector.

Sorry, this took a back seat for a while. I made up the adapter, and it needed 2, 3, 5, 7 and 8.

I can't seem to get the same adapter to work with my older k-series servers though. I get output to the screen, but can't imput.

More playing around I guess.

Hi Robin,

what is exact type and name (or model number) of your Lantronix console switch?

It's a Lantronix SCS3200.
I'm just trying to work out now, why the connection works perfectly with the rp3410 using a DCE RJ-45 to DB9, but not the K-Class.
I'm tried testing it by connecting my laptop direct into the back, and both work when I use a DTE adapter at the laptop end, and a DCE adapter at the server end.
