hi, please help me understand what i'm doing wrong, it's maybe an easy question but i've spent countless hours searching in google and trying everything and still don't get it. i have a new bosch autodome easy II ptz camera* that shows image but i've been unable to control it so far. i'm trying to first of all set the camera address address on the OSD (since there doesn't seem to be any other way) by calling the PRESET 95 with a cheap PTZ remote controller i got for initial testing like the one in the attached image. both speak pelco D and P protocols and the bosch camera has autobauding (it is actually showing "AutoBauding..." the whole time) well, the first thing that confuses me is that i have to tell the controller/keyboard/cheap remote the camera address i want to talk to when the camera does not have any address set yet, how does this make any sense? but ok, the camera's instructions say that if the address is set to 0 it will respond to commands sent to any address so my first guess is that it will have set address 0 from factory until i assign another one, but i set it to target camera 1, 2, 3..0 and when i try to call preset point 95 nothing happens, it just keeps showing "AutoBauding". i tried with both P and D protocols and different baud rates (1200, 2400, 4800, 9600) and while using pelco P i even tried all possible addresses (0-32) and still don't get the OSD or any response to zoom+/- or move right/up/down/left. per camera's instructions it is connected to the controller +/A to + and -/B to -. i tried to SET preset 95 as well instead of just calling it, but still nothing i know i'm missing something but the camera is sitting here for months and i have tried everything that comes to my mind. maybe i just should keep searching, is there any good introduction into this subject or how did you guys learn what presets are etc, only from the operating instructions? i haven't found anything besides specifications and manuals and still don't understand what i'm doing wrong * http://www.boschsecurity.us/en-us/autodomeeasy/

thanks all so much for the responses! SEANHAWG what you said that 2 out of the 3 you ordered didn't work made me suspicious and after some testing it looks like this is the problem here too. since i don't have an oscilloscope i could never verify if the controller was actually working and the multimeter didn't tell me if something was going on either, but i wasn't sure if it's fast enough to notice the couple of bytes that are sent so i just assumed it did work (well, it's new..). now i have tried with an RS485-to-USB adapter and a shareware version of a software PTZ controller i've found and the camera works fine, i've tried with both pelco P and D and at different baud rates and the camera responds perfectly. there is no such thing as preset 95 in the program but directly a "menu" button that made the camera display the OSD Soundy i considered reversing the polarity of the RS485 line more than once but didn't dare since i'm not sure if this can damage the camera, is it safe to do? shockwave199 you are right, there are other presets defined in the manual like autoscan limit stops and preset tours but i was always considering the camera address as the priority, how can you talk to a camera without address that has no dip switches but is configured in the OSD? it looks like the initial address is 0 since it did respond (which makes sense) and the problem was the remote-controller-thing all the time i can continue now learning how zoneminder works and i'm very happy to know the camera works fine. again thanks a lot!

hi shockwave199, yes, it is hooked up the same on each end, positive to positive and negative to negative (it's what i meant with +/A to + and -/B to -). the camera supports besides RS485 also biphase, but i didn't connect those wires to anything. and the manual says it is configured from factory for RS-485 operation in pelco protocol mode. i just tried to hit the iris button, short and long press, using pelco D and P at different baud rates and still don't get any response, but thanks for the hint and your feedback! the camara seems to be working fine, the problem is most likely the person operating it when starting up it does initialize and find it's home position but that's all it does, then it just says AutoBauding. what makes it more complicated is that i don't have the background, i don't know if it's possible to talk to a camera without specifying target camera address first - according to the manual if the camera address is zero it should react to all commands no matter which target address you choose, but it looks like it does not react. i've searched for "default address" and couldn't find anything either, i called bosch and they said they don't give support to end users and directed me to the seller that couldn't help me either. and the seller of the remote control didn't even know what i was talking about when i asked about preset 95 and using it to open the OSD (something that seems to be standard to open the on screen menu on PTZ cameras). since i'm completely lost now i wanted to try asking the experts here here is some information about the remote control if anyone is wondering how the thing works: http://www.ebay.co.uk/itm/Pelco-D-P-RS48-Remote-Control-IR-PTZ-Camera-Controller-/130626854682 -no intention to advertise this seller, it's not even where i got mine from, but i will remove the link if anyone feels it's not ok to post it here thanks again shockwave199!
