Please help, Problem about transmiting data from Mindray BC-3000 Plus to Host computer. I Configure Mindray BC 3000 Plus for Data Transmit through Host Computer. I am Receiving Strange Data Through Serial Port. Configure parametter on Mindray BC 3000 Plus : Using Serial Port 2, Baud rate (9600), Data bit (7), Stop bit (1), Parity (None), Handshake (Off). Is there any solution ? Thanks you so much.

Shandon Histocentre 3 embedding center. This unit is intermittently losing the date and time, and shutting off the paraffin tank and tissue tank heaters. The voltage across the super capacitor on the control board is normally about 4.5V, while the instrument is plugged in, and drops to about 3.6V (which it holds steadily) when the instrument is unplugged. What I have seen, when it fails, is that the date and time is wrong (year shifts back to 2000), the tank heaters turn off, and the voltage across the super capacitor drops to about 2.9V. The voltage on the super capacitor stays at that low voltage, until the instrument is power cycled, after which it immediately begins charging up (eventually getting back up to ~4.5V). The time and date can be reset, and all functions seem normal. Many years ago I had to replace a super cap on one of these control boards, but this seems like it is something else on the control board. Has anyone run into something like this? Does anyone know of a facility which has replacement control boards? Does anyone know of a facility which has experience rebuilding these control boards?
I'm having problems with the temperature sensors, the black needle of the gauge hits hard the limit of the scale and stays there forever. The voltage divider of the galvanometer seems to be fine, all resistors are ok. I'm suspicious about the sensors. I can see that there are 2 of them. I have removed the lateral lid and am able to see clearly a K-type thermocouple wrapped inside a pipe and, strangly, its yellow connector is loose, it is not connected to anything. I don't see where it could be attached. As for the other sensor, it is the one inside the cylinder of the evaporator, it looks very strange to me, I cannot tell what kind of sensor it is, at first sight it resembles an optical fiber, it seems to have a core, but I'm expecting a thermistor or some kind of semiconductor like an LM35 or something like that. Coming out of the chamber there are two red wires connected to the sensor which outputs 2.7 V. So, my specific questions are: 1) Where should the thermocouple be connected?, 2) What kind of sensor is the one inside the chamber? 3) What should be the output of the sensor located inside the chamber? Thanks a lot, I would really appreciate your help.
I am getting intermittent diluent sheath empty errors. Clearing the fault, refills fluid and background is good. Ran the low control, ok. The normal and high control wbc counts are high. I see blood in lines on the right side around 11,12,13 valves after a sample is run. Is that normal? Any input on high wbc on controls?
