The front of the unit has an RJ45 port (EIA-232) and has a wiring diagram on how to wire it to a DB9 port so you can connect it to a PC. Here's the diagram: If I use standard TIA-568B wiring for the RJ45 connector:

2014年11月19日 · Connects the RJ45 RS232 serial port s of EDS-MD to a DB9M DTE interface of a PC or serial device to check that serial ports in the EDS- MD are functioning properly. but this one has no drawing.. so i looked at the rest and searched for the 'DB9M DTE'

2013年3月31日 · For RS232 compatibility the TX/TXD+ signal must get routed to pin 3 (DTE) The second driver is used for RTS in 232 mode, thus the RTS/TXD- signal must get routed to pin 7. As can be seen, the pinout of the right hand table (above) is emerging. If you continue the exercise, CTS/RX+ end up on pin 8 and RX/RX- on pin 2.

2011年8月10日 · These adapters work well, I have used them for RS232 many times before. As far as the pin out of the RJ11 you need to see what device it connects to and which pins correspond to the db9. The standard db9 pin out can be either a male or female connector and also DTE or DCE. You need to know what you are connecting to before you can determine the ...

2015年5月20日 · They both have rs232/rs485 capabilities, just depends on a switch on the back of the terminal and both connections are with a rj45 jack (I will attach relevant manual). And connect via a RJ45 cable, and I want to connect it to a computer. Now, I've set up a .vi that should be able to connect to, or at least discover, the devices but to no avail.

2019年6月9日 · I'm looking to splice wires from a DB-sub (9 pin) connector out to a breadboard but I'm getting different pictures for color-coding which makes me confused. What's more confusing is the connect I h...

2011年2月20日 · I stripped a DB9 extension cable which I will use to connect to a DB9 connector on one end and an RJ45 on another. I need to make connections to pin 2, 3, and 5 on the DB9 side. When I stripped the DB9 wire, I was surprised to find 5 wires, since there are 9 pins in a DB9 connector. Why are there 9 pins but only 5 wires? One of the wires is ...

2023年7月21日 · No, because the RS-485 standard itself does not define any connector or any pinout, among many other things that the standard does not define. Also a DB9 connector does not exist, but I will assume you mean DE9 connector. However, many other standards that build on top of the RS-485 standard do define a connector and a pinout.

2020年6月19日 · There are two standards for DB9 pinouts when it comes to CAN bus. This seems to be the industrial version. I've seen it in PLCs and VFDs. 7 - CAN-H; 2 - CAN-L; 3 - GND; 6 - GND; 9 - VBAT; This seems to be automotive. The only place I have seen it is in OBD2 to DB9 cables. 3 - CAN-H; 5 - CAN-L; 1 - GND; 2 - GND; 9 - VBAT

2016年12月11日 · RS-232 specifies a DB-25 connector, but I have seen DD-9, RJ45, din8 and other connectors, and other than hooking a modem to a pc I have never been able to use a COTS cable for any rs232 project. Fortunately 90% of the time a couple adapters will do or a custom cable, they are easy to make. \$\endgroup\$
