Why does the description say "RS232"? This seems to be for TTL, which is 3.3v and not compatible with RS232.

This is TTL. It will not talk to a true RS232 device. RS232 signals are inverted TTL - i.e. a "mark" in TTL is high (+3.3v or +5v), but in RS232 it is low (-13v or whatever). RS232 != TTL

Here is a discussion of the voltage levels and logic signal protocols of RS-232 and TTL:https://www.sparkfun.com/tutorials/215USB uses TTL voltages (0/5V) so the unit converts the RS-232 voltages into the USB TTL.

I was also confused at first. It is USB to TTL. I believe the TTL is buffered in the adapter with an RS232 interface chip which probably provides electrical isolation as well.

This is correct - RS232C does not use TTL levels and so strictly speaking this adapter isn't "RS232". However it does provide the same set of signaling wires and the same logical protocol as RS232C.

It doesn't work at the logic voltage level that the technical rs232 spec requires. But the communications are serial protocol. You would need a logic level converter to use this with rs232.

Click on the thumbnails to the left of the main product photo at the top of the listing. There are some helpful photos and diagrams there. The 3 terminal connector on the top board is a serial RS-232 connector (GND, RX, TX). One photo shows "NC" for the two terminal connector but another shows it connected to a battery that is being charged and there it appears to be used as a voltage feedback monitor.

I tried it with my D5100 and couldn't TTL... maybe did the wrong settings !

I have a D300s, but these are manual syncs. There is no reason why they should not work. You will not have access to TTL though.

no. if you order it and send me a email i will send you the correct ttl flash

Yes. It is not TTL, but it works very well manually. I use it with the E-PM2.

It does not work for TTL with my Nikon D5100 and Sunpak PZ42X Flash. It will work when the flash and camera are set to manual. The Sunpak right on the D5100's hotshoe works fine, but adding this flash code results in extreme overexposure. I'm puzzled, because all the pins look right, and continuity checks out.

I use a D3200 and it does/did not work in TTL mode. I wrote to Vivitar and got emails of mumbo jumbo they did not understand the glitch at all!! Also a Sunpak PZ40x flash. Now the cord would work in the manual mode so the wires were OK but still does not support iTTL of Nikon.I have order a different cord elsewhere and am waiting for it arrive.

I bought this product (MP OTG300 LTOP) and the tiny print embossed in the plastic on the bottom says "Electrical Rating 125v 15A 1875W 60Hz". No hint that it's rated for 240v. I did NOT buy it off this Amazon site, where it's referred to as "Worldwide", so maybe there are two versions of this device, both designated MP OTG300 LTOP, one good for use at 240v and one not. If that's the case, you need to be certain which one you're really buying. The text on the outer packaging gives no clue; I had to remove it from the package and look at the fine print on the bottom.

Did you tried manyal mode? Though it has multiple connection as it works like supporting TTL, it does not support TTL.

The transmitter is universal and will mount on any hot shoe. It will provide standard flash triggering with no TTL functionality. You will have to manually adjust the flash settings and simply use it as a trigger.

try a different store, it's a common battery for both transceivers and the correct battery can be determined by the size of the used one, if you don't have a batt in hand to use for size, use the internet for the latest cross over to common number based on the batt number you have in hand or in the book............... it's no big deal or i'd look up the sizes I am using I bought last week. write again if you really have probs!!

I am pretty sure it doesn't support TTL, the user manual was pretty poor. I returned this product.

Seller1ON1 sent the STA-U17WD model which is 5.1V, 0.7A, instead of MCS-01WD which is 5V, 1.2A. I ordered this expecting the 1.2A charger, so I'm returning it.

No, this one is specific to the TTR125 - but we have another one listed for the TTR230. Thanks. Ginger

It is for a standard 9-pin DB9 RS-232 serial connector according to the literature provided. It does receive a 9-pin plug, just couldn't get it to recognize the device that I was trying to connect.
