Q: What is the format of the RS-232 messaging from the MX300?
A: The MX300 broadcasts RS-232 concentration data with resolution of 0.1% O2 approximately once per second. The baud rate is 2400; there are 7 data bits with odd parity.
Each bit is as follows, in ASCII:
Byte 0: Hundreds digit
Byte 1: Tens digit
Byte 2: Ones digit
Byte 3: Decimal point (0x2E)
Byte 4: Tenths digit
Byte 5: Carriage return (0x0D)
Byte 6: Line feed (0x0A)
For example, a concentration of 78.9% will output as follows:
0x30, 0x37, 0x38, 0x2E, 0x39, 0x0D, 0x0A

Q: Concerning the installation of the MX-300, there is a blue "T" in the box. One end goes to the air supply, one end to the sensor. Is the third end open to the atmosphere?
A: Yes, this is the T-flow through adapter. The sensor should be vented at atmospheric pressure.

Q: Is the T adapter reusable?
A: The adapter is not reusable. It is a disposable T adapter made of high density polyethylene.

Q: The blue T-adapter diffuser has a spider web obstruction in the tube. The old ones did not have this construction. Can you please tell us why?
A: Teledyne has sold different types of T-adapters in the past. The current blue T-adapter is multipurpose, and the spider-web inside does not effect its use.

Q: Can you tell us the response time of this monitor and/or sensor? Does it take longer to change its displayed reading with a high or low flow of gas?
A: The response time is determined by the sensor. And yes, an insufficient gas flow will cause a slower response.

Q: What is the maximum flow rate for the MX300 / AX300?
A: When used with the provided T adapter, we have not been able to identify a maximum limit. We have run the device at up 80 scfh and found no change in concentration due to flow rate.

Q: What is the update rate for these units?
A: About once per second.

Q: Can you please tell me if the blue T adapter can be autoclaved and if so to what temperature?
A: The Blue T adapter is not intended for Autoclaving. We do offer an optional version of the T adapter that is autoclave suitable. (part number A274). Your local representative who supplied the units to you should be able to also supply you with the optional T adapter.

Q: Do you know how long the unit might continue to operate when the low battery indicator shows no bars left?
A: We have no specific data on this condition, but from our limited data we can hypothesize the unit could go for 4 to 5 days in a non-alarm condition.

Q: Do you still sell the universal mounting clamps for the AX300/MX300?
A: Yes, the universal mounting clamp for the AX300/MX300 is part number CP2345.
