...as boxes (extended characters) which suggests some kind of electrical interference. I've tried with two USB to UART devices (one based on PL2303 and another on ARK3116) and they both behave the same way. Has anyone else gotten a UART on one of these more recent devices (ones with the new...

...a USB to TTL converter. Then you can read the system/bootloader. From here you can default the recorder. When you use a converter such as a PL2303TA based device or similar. U need an old USB Driver version 3.3 (not higher) because higher isn't supported by windows 8 and higher. Futher...

Don't connect any voltage from the USB cable AT ALL.

i found a pl2303 but the positive voltage line is 5 volts. is this ok?

...file size limit of the tftp updater (though there is a workaround for that), which is here : https://ipcamtalk.com/downloads/tftpserv.9/ Easy enough to try. Then if you want to try the serial console you'll need a serial TTL to USB convertor, something like a PL2303-TA based device or similar.

Hi, It seems that PL2303 was faulty. Ordered a different USB to RS232 TTL. After replacing PL2303 with CH340 all data received from DVR was OK. Breaking into boot loop with Ctrl+u and firmware flashing went smooth... Finally... As a bonus, I also revived a Hikvision DS-KV8102-IM TCP/IP outdoor...

The PL2303 device will be perfectly fine. Even with the wrong firmware there should not be garbage characters. Did you log the transcript using the 'copy all to clipboard' in PuTTY? Did the screen show the same as the file you posted? Sometimes the raw log using the PuTTY inbuilt logging...

Hi, Thanks for the reply. I have connected the onboard 4 pin header. The USB to RS232 TTL is a PL2303. I'll try to find a MAX232 based converter (level converter), so I'll be able to use a standard RS232 PC port. Back to file I attached, it made sense to me that once some of the strings are...

As the subject heading says I have a counterfeit Pl2303hxa which I last used with win 8 after rolling the firmware back. I now have win 10 which loads it own firmware and the above message is displayed by device manager. There’s a number so call work arounds on the net for win 10 but none of...

...location tomorrow and will need to test it on a NVR there as I now have win 10 and had to down grade the driver to day to remove device error. (Pl2303 HXA clone) I am a windows guy only and at present don’t have a working Linux set up. If need I will set it up again as a dual boot on my laptop.

This converter use to work on these ports as well. I do have a small flasher with RJ45 connector port which i use to flash HIKVISION DVRS AND IPCS.

What you showed in the video is an RS-232 DB9 interface on the NVR. A PL2303-based serial TTL to USB convertor will not work with that - it's a different type of interface. Serial TTL uses unipolar signals of 0 - 3v RS-232 uses bipolar signals of +- 3-15v Connecting a serial TTL interface to...

t Yes Ive tried with another PL2303-baed USB to TTL serial convertor but still same problem. The problem just came after reinstalling the OS both win 7 64 bit and win 10 64bit.

If you join RX to TX from the USB to serial convertor, do characters typed get echoed? Have you tried another PL2303-based USB to TTL serial convertor? Maybe the one you are using is broken. In my experience, they can be quite fragile, I usually buy several at a time.

That's a pity - the response means that the firmware in use is not vulnerable to the 'Hikvision backdoor' - which is unexpected, given that thge apparent version is older than 5.4.5 Actually - or maybe not older, if the last number is an ascending numeric as opposed to a decimal fraction, if you...

...but dont see yet any hardcoded sequences. is i see it expects that password will be not more 0x10 bytes, so it strips it anyway to 16. As i uderstand, if i will conenect with serial PL2303 i will have the same tftp server.... Do you think, any chance to get into ssh of CAM without user/...

It took me less than a minute to find 3 of these at a Romanian supplier. CP2102 USB to UART Converter Module Red PL2303 USB to UART Converter FT232RL USB to Serial Converter ** Obviously other suppliers make more sense for anyone looking for these who isn't in Romania **

...so that I can verify the differences? Maybe we have a different HW-Version, that would explain it. The connector you are connected to with ur PL2303 is the RS485 port, you will not get anything useful out of it with this usb-serial converter. Anyhow the RS485 has nothing to do with...

A small update. I tried with 2 USB-to-TTL converter based on PL2303 and CP2102. In both the case, i can read garbage data. I also found that when the GND of USBTTL is connected to GND of the NVR, no data is read. When when it is removed i can read garbage.

Yes, a PL2303-based serial TTL to USB adaptor will work OK. And the wired connectors look OK too. It won't be published openly.

Oh great, thanks for your info, by chance I already purchased this usb adapter: 1PCS PL2303 TA USB TTL RS232 Convert Serial Cable PL2303TA Compatible with Win7 Win8 Win10 vista-in Integrated Circuits from Electronic Components & Supplies on Aliexpress.com | Alibaba Group And this cable 10 SETS...

A couple of items required : A serial TTL to USB convertor - a PL2303-based version works OK. A 4-pin 1.5mm JST ZH wired connector - usually in 10-packs. Is this about 2 - 3 seconds after power on? If you haven't done so already - leave it powered for around 10 minutes or so and re-check...

Thank You very much for Your reply - I have bought a usb serial ttl converter - maybe this will do. USB 2.0 CH340G TTL Konverter Adapter CP2102 PL2303 UART FTDI Arduino 5V + 3.3V | eBay Thank You

That will be the cause of the problem, I believe. TTL level signal are mono-polar, 0 to +3v RS-232 signals are bi-polar, +-3 to +-15v They are not compatible. It looks like you need an RS-232 to USB convertor.
