Page 2: General
Instead the six pins were given the names indicated above (which are names taken from the schematics of the 6150AD). All further discussions of the signals will refer to these names. The colours in parentheses are those of the wires in the Automess standard probe cable. So the easiest way to access the signals for testing or for connecting some user equipment would probably be to cut a standard probe cable into two equally sized pieces, which would give two test cables at a time. -

µs) as derived from the internal quartz. Term acts purely as a transmitter, there is no way to feed data into the 6150AD or to request a repeat in case of transmission errors. Also, there are no handshake signals to control the Term output. -
Page 4: Software Characteristics
06/2003 Technical Manual 6150AD Probe Connector Page 4 of 14 A typical setup to read the 6150AD by a PC (optionally with a probe connected) would be: standard probe cable DB-9 probe (optional) connecting cable »PC - 6150AD - probe«... - Page 5 16 bit positive mantissa and byte 5 is the signed (-128...+127) 2-based exponent. The unit is µSv/h (pulses per second for pulse rate indicating probes like 6150AD-k, AD-17, AD-19). Byte 6 is the XOR (exclusive OR) of Bytes 2-5 and is intended to be used as a block check character to detect transmission errors.

Page 6: Control
If any other or no probe is connected, Control will always be high. Certain software versions of the 6150AD (e.g., the Swedish version V-36.04) make additional use of the Control output: With the AD-t probe, Control will operate as described above. With any other or no probe the Control output will signal dose rate alarm: Control = high indicates that dose rate alarm is off, and Control = low indicates that dose rate alarm is on. - Page 7 The 4.75V output voltage is generated inside the 6150AD out of the battery voltage by means of a switched regulator. It is individually tested in serial production to be in the range of 4.65V to 4.90V with a typical value of 4.75V (at an input battery voltage of 7.0V).
