Pressure Systems, Inc. Model 9046 User’s Manual Page 16 www.PressureSystems.com 2.6 Read Sensor Type Each channel type can be read using a command of the form: uxxx51 . where xxx = the channel # in HEX . Example: • u00a51 will return 18, indicating the channel is configured for a type T thermocouple.
Pressure Systems, Inc. Model 9046 User’s Manual Page 17 www.PressureSystems.com Command: c05 0002 Action: Enable thermocouple reference temperature alarms in autonomous data stream.
Pressure Systems, Inc. Model 9046 User’s Manual Page 18 www.PressureSystems.com 2.8 Set Temperature Units Set temperature units for all temperature channel s. The ‘v’ command is used with array index aa = 11 (hex) and new coefficient index = 0b (hex).
Pressure Systems, Inc. Model 9046 User’s Manual Page 19 www.PressureSystems.com The following example sets channel 1 EU filter parameter to 10: Command: v00152 10 Normal : A Response: Error: N08.
Pressure Systems, Inc. Model 9046 User’s Manual Page 20 www.PressureSystems.com 2.11 Read EU Filter Parameter The EU filter parameter can be read for an individual channel using the ‘u’ command with coefficient index number 52 hex. The following ex ample reads the EU filter parameter for channel 1.
Pressure Systems, Inc. Model 9046 User’s Manual Page 21 www.PressureSystems.com 3.0 Calibration Calibration consists of offset correction. Implement offset correction (automatically calc ulate and set offset coefficient) on a per channel basis using the ‘h’ command.
Pressure Systems, Inc. Model 9046 User’s Manual Page 22 www.PressureSystems.com Examples: Correct the offset in channel 1 with channel 1 at 100 degree C : Command: h0001 100.0 Response: 0.294167 (offset coefficient returned) Manually set channel 1offset coefficient to 0.

Pressure Systems, Inc. Model 9046 User’s Manual Page 24 www.PressureSystems.com 4.0 Firmware 4.1 Description of Operation Table 1 shows the different sensor ty pes available along with the gain settings and engineering units for each type. Setting channel sensor type automatically causes the gain for that channel to be set according to Table1.
Pressure Systems, Inc. Model 9046 User’s Manual Page 25 www.PressureSystems.com Voltage If a channel is configured for straight voltage then no additio nal EU conversion is needed. Va is returned as transducer voltage. Vb is returned as cold junction temperature.
Pressure Systems, Inc. Model 9046 User’s Manual Page 26 www.PressureSystems.com 4.2 Updating the Firmware Special precautions must be taken when updating NetScanner™ firmware. If care is not taken, the module program memory can be corrupted rendering the module inoperative until the program memory chip is physically replaced.

Pressure Systems, Inc. Model 9046 User’s Manual Page 45 www.PressureSystems.com When the hardware trigger is used to synchronize stream scans ( sync = 0), it is assumed that the user would prefer to also synchronize internal data acquisition cycle.
Pressure Systems, Inc. Model 9046 User’s Manual Page 46 www.PressureSystems.com The ‘ f ’ parameter identifies the format of each selected acquired datum in each data group of the stream scan, and is a single numeric digit.

Model 9046 User’s Manual Page 51 www.PressureSystems.com 5.7.3 Command ’c’- Sub-command Index 02: Stop Stream ( s ) This sub-command is used to stop (or temporar ily suspend) the delivery of any previously started host stream in a module, one at a time or all together, whether the stream was unbounded or bounded.
Pressure Systems, Inc. Model 9046 User’s Manual Page 52 www.PressureSystems.com Example: Stop all the streams configured in the previous example: " c 02 0 " Read response: " A " .
Pressure Systems, Inc. Model 9046 User’s Manual Page 53 www.PressureSystems.com 5.7.4 Command ’c’- Sub-command Index 03: Clear Stream ( s ) This sub-command is used to "undefine" any previously configured host stream in a module, one at a time, or all together.
Pressure Systems, Inc. Model 9046 User’s Manual Page 54 www.PressureSystems.com Note NUSS uses this sub-command to undefined data specific streams when its Run State Editor form is used to define "custom" stream configurations (called Run States 1-9) and all three streams are not to be generated concurrently.
Pressure Systems, Inc. Model 9046 User’s Manual Page 55 www.PressureSystems.com 5.7.5 Command ’c’ - Sub-command Index 04: Return Stream Information This sub-command returns current stream configuration information in its response.
