RJ45, in combination with a LoPy

@Shaun
Sorry for spam
I see that you are using the same green connectors as me - i use it near to always as servo connector :)

@robert-hh The converters can be configured live over Ethernet using configuration software that is downloaded from the suppliers website.

The modules even include a webserver with a configuration page that enables parameters to be changed

Hi shaun, thx for the tip, do you know if the USR-TCP232-T unit (https://www.elektor.com/ethernet-module-usr-tcp232-t) should also work out for my situation (in your experience)? This module is available in the Netherlands the other (your unit) is only available outside Europe, That means long p&p times :-(

It's on ttl level :-)

[Shaun]

@joena Yes, I have used the older model as well (larger can xtal), the newer module has the smaller smt xtal.
They all can work as a simple Ethernet to UART (3V3 TTL) bridge the same way a USB to UART converter works.
A computer must load the Ethernet virtual serial port driver.

@Shaun thx shaun, Just bought the module, see how it goes :-) thx for the tip

@Shaun hi Shaun, the TTL <> RJ45 module has arrived :) it even was the same version/model as yours :) so I was very glad (I didn't expect that ;)) I have a question...

I found the manual quite challenging, perhaps it's my lack of understanding (technical) English, or perhaps the Chinese people think in too technical terms ;) But how did you set up the module?

My situation is as follows,
I have a LoPy,
I have a USR-TCP232-T2 module
I have a Extron MLC 104 IP PLUS button/control panel (for controlling the av equipment in a classroom)

With my LoPy I want to sent TTL signals (Tx/Rx) to the USR, which converts them to RJ45 (IP: 192.168.254.254, Subnet: 255.255.0.0) which is connected to the Extron button/control panel.

For the USR I can select a few things, but I guess I need TCP Server? Could you elaborate how you did your setup?
My guess would be to first connect it via ethernet (patch) cable to local laptop and make the USR a TCP server, than use a cross cable to connect between the USR <> Extron button panel?

I can also adjust IP addresses, but I guess I need the USR IP (to access the module) to remain the same and the target IP to be the IP of the Extron button/control panel?

i Hope you can help me out with this? With regards, Jeroen

in addition, do you Shaun (or any others off-course ;)) know of a good video for any help in this matter (with this module)? On you-tube I saw a video in Spanish (but I'm looking for English or Dutch :P)

@joena Is there at all WiFi at the location? Then LoPy can use WiFi and the AV equipment RJ45.

@joena said in RJ45, in combination with a LoPy:

Extron MLC 104 IP PLUS button/control panel

Hi Joena.

The module can be configured using the software download from the supplier;
http://www.usriot.com/usr-m0-setup-software/

The simplest configuration is using UDP mode.

One can create a virtual serial link between 2 or more modules.
or
Create a virtual serial link between 1 or more modules and a PC running the virtual serial over Ethernet driver.
http://www.usriot.com/usr-vcom-virtual-serial-software/

I'm not familiar with the " Extron MLC 104 IP PLUS button/control panel", but it sounds as if you are not wanting to connect a USR module to a TTL serial port on the Extron, in which case the Extron will then need to be able to run a custom driver or application that you provide and load onto it, that will then communicate with the USR module.

Example code can be found here;

@papasmurph Hi grote smurf :) At work there is WiFi available, but it's managed by another (IT) department. If there is going to be a fixed 'wifi device' connected to their wireless network (read 100+ connections per building) their gonna give me issues with IP connections, security, etc. I know you can do add a separate VLAN for this, but I want it to work independently.

Thanks for your answer though... Grts, Jeroen

@Shaun Thx so much Shaun, i will try this out. Will let you know how it goes. thx again, Jeroen
