EBME Forums Forums Thread Like Summary - M1026A RS 232 protocol and Settings

Hi friends

Wishing all of you be fine

I´m trying to connect a very old M1026A by RS232, does anyone have information about the settings of the serial port and the communication protocol?

I guess this unit was created by Andros to Phillips because it has very similar parts to the 4800 Andros units but I was unable to establish communication with the 4800 or 4700 configuration

Any help or ideas will be appreciated

Thanks in advance

Hi Diego, I've sent you the two manuals that I have found, let's hope they help.

Stay Safe

Apparently, the information you require is (probably) contained within an HP (and possibly Philips) document entitled "Connection of Devices via the MIB/RS232 Interface".

Unfortunately, I have been unable to hound that one down on the Magic Web.

However, this site may provide a few encouraging clues.

By the way, the reference book cited in that link (namely, "Interfacing the IBM-PC to Medical Equipment: The Art of Serial Communication" (1995)) is available from Amazon, eBay et al. I don't have that one myself, but perhaps I'll come across it one day.

Frank has the manual, but I'm guessing you already have that.

Buena suerte!

There have been various post on similar questions so you could try doing some forum searches. There also used to be a guy from Philips, Chandana S, who was very helpful but I'm not sure if he is still active.

Good luck, Dave

I used to work on the old Kontron gas benches and the Andros cable would only communicate one way. Its possible that you just need to swap the ends around as the cable only communicates one way. This was always annoying when staff had been moving equipment and connected it the wrong way, they phone and you ask them to swap ends and they simply laugh and explain that a cable cannot do this. I would then attend and swap the ends and get it working, the look on their face was always priceless.

That's an interesting one!

Can you remember what was special about the cable. "Null modem" maybe, or a disconnected wire somewhere?

Later set-ups (Agilent et al) may have used 25-pin D-shell to RJ45, I believe.

Meanwhile, here is another .pdf that may be of interest (Andros 4620). A serial connecting cable is shown at page 4-4, and the Comms Protocol is described at Section 6. All that may not apply in Diego's case ... but, on the other hand, some of it may (as OEMs generally stick to their original set-ups in my experience).

Hi Diego, I've found this: Philips-Interface-Programming-Guide probably the great-grandson of what your after but there may be some pointers inside this tome......

send me your email address.
