need help re: time code RS232 v. RS422 device

[Rebecca Lundwall]

I have been struggling with this for over a month and could really use some help in order to purchase some equipment and begin running an experiment in January.

 

I am looking at purchasing an RS232 time-code device and a camcorder and need to know a little more about the signals used. I have computer / video support (at the University and from a vendor), but they want me to get answers to a few questions before we try a mock up and then purchase the equipment.

 

1. Is RS232 still the way to go with E-Prime? (I see no mention of RS422 but one video equipment expert is telling me this is more common).

 

2. Horita (one brand of time stamp device) uses Sony prototype and the vendor tells me that most time stamp devices will use this. He wants me to verify that E-Prime can accept Sony prototypes. Does anyone know or know how I can find out? E-Prime tech support told me they are swamped right now (when I asked about another issue) and this may also be an issue outside what they normally offer support for. (I'm also a little confused as to why he thinks E-Prime needs to accept the Sony prototype, so maybe someone can explain that to me, too??)

 

I realize I'm a newbie here, but any help would be very much appreciated.

 

Please excuse the possible cross-post at pstnet.com/forum

 

Thank you.

Hi Rebecca,

I'm not very familiar with the specific device you mention, but in general RS232 is no problem for EPrime. 

From a programmers point of view, both RS-protocols are identical. It's the hardware that is slightly different. (I think RS422 is the 'industrial' sibling of RS232.)

Implementing the communication protocol using inline (EBasic) script could be a challenge if you don't have any programming experience. 

However, when communication only consists of sending simple characters strings from the PC to device, programming is rather straightforward.

Thank you. That is enough to get me going. You have helped more than you realize, I'm certain.

I have done this once before using different equipment, a parallel port, and a little inline code. I'll eventually get there. Thanks.

Best wishes,
