My friend owns one of these and he's looking for user and service manuals plus some kind of programming/reference guide for RS232 bridge: Does anyone happen to have them in scanned form?

In addition, I'd be also interested if the sister models from same release line (ie. CLD-V2800) share the same bridge programming functions thus making it possible to take advantage of their guides instead?

That looks like the dual standard version of the CLD-V2400 so the RS-232 should be the same as the 2400, 2600, 2800, LD-V4400 and 8000

Thanks, I'm not familiar with differences between each model in 2x00 series but I guess I can safely assume that 2300 and 2400 share pretty likely the same features function-wise then. I think I saw programming guide for 2400 online somewhere when I searched for them last time, if I manage to find it again then there's only service manual left to track down

It looks to me like all the functions would be the same. I have 2400 information but not a PDF
