Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Chapter 3 Programming and Operation 3.1 Commands & Responses 3.1.1 Introduction This chapter describes all commands a host computer program may send to each of the NetScanner™ System Intelligent Pressure Scanner modules (Model 9816) that are connected to the various slots of the 98RK-1 Scanner Interface Rack chassis, as well as the data or status responses returned by these modules.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© transmissions by sending commands to the modules, which are normally servers. However, a module can initiate its own transmissions in some operating modes (e.g., the hardwaretriggered or free-run autonomous host streams generated by the Configure/Control Autonomous Host Streams ('c') command). A maximum of 255 modules are easily addressed by varying only the low-order byte of a typical IP Address.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© From this schematic, it should be clear that the command letter (c) is required, the position field (ppppp) immediately follows it, and may have 0, 1, 2, 3, 4, or 5 characters, and there may be zero or more datum fields ( dddd), as required. For simplicity, the variable length nature of each "dddd" string is not shown [with brackets] above, but the required leading space character is shown. The position field is similarly simplified (as “ppppp”) below.

At any point during module operation, the Reset ('B') command may be used to return any module to its default “reset” state. If the module is then required to enter any other states (that were previously programmed for it by the host), the host must then restore these states accordingly using the appropriate commands.
Pressure Systems, Inc. 3.1.5.3 98RK-1 & 9816 User’s Manual© Calibration Adjustment of Offset/Gain Correction Coefficients All NetScanner™ System Intelligent Pressure Scanners have built-in software commands (and pneumatic hardware) to perform a periodic zero and span calibration adjustment of its internal or attached pressure transducers. Use of these periodic adjustments result in the highest possible data accuracy. The result of these calibrations is a new set of internal offset and gain coefficients.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© The above correction coefficients are maintained internally in IEEE floating-point format. The Read Internal Coefficients ('u') command and the Download Internal Coefficients ('v') command can return (or manually set) calibration coefficients to the host in decimal or hex dump formats in their responses. 3.1.5.4 Delivery of Acquired Data to Host Several commands apply to host delivery of acquired data, either on demand or autonomously.
Pressure Systems, Inc. 3.1.5.6 98RK-1 & 9816 User’s Manual© Other Functions Some commands may be used at any time to obtain information about the internal setup and status of a module. The Read Module Status ('q') command is an example. Also, the Set Operating Options ('w') command, though generally used after power-up reset, may also be used at other times as well to change system operation.
Pressure Systems, Inc. 3.2 98RK-1 & 9816 User’s Manual© Detailed Command Description Reference All commands applicable to the Model 9816 NetScanner™ System models are described on the following pages and summarized in the following table. Table 3.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© POWER UP CLEAR (Command 'A') Purpose: This command has no internal module affect. It is used as a simple method to verify proper communications to the 9816 scanner. Command “A” ‘A’ is the command letter Response “A” ‘A’ is the acknowledge letter Description: The Ethernet Model 9816 does not return a ‘Power-Up Clear Expected’ error (as did early 901x modules without Ethernet interface).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© RESET (Command 'B') Purpose: Instructs the module to reset internal operating parameters, and to set all internal control variables to their default “reset” state (see description below). The current TCP/IP socket connection will remain open. Execution after a power off/on cycle is optional (unnecessary).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© CONFIGURE/CONTROL MULTI-POINT CALIBRATION (Command 'C') Purpose: This command is actually four (4) sub-commands. The first configures and starts a Multi-Point Calibration adjustment function for selected channels in the module. Another is repeated multiple times to collect data for each defined calibration point. Another ends the calibration function normally by calculating new offset and gain adjustment coefficients from the collected data.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'C'— Sub-command Index 00: Configure & Start Multi-Point Calibration This sub-command has four (4) additional required parameters used to configure and start the Multi-Point Calibration function. Command “C 00 pppp npts ord avg” Response ‘C’ is the command letter. ‘ 00’ is the sub-command index (ii) for Configure & Start.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Example: ● Configure and start the Multi-Point Calibration function so that it affects only the first four (4) channels of the module. Three (3) pressure calibration points will by supplied when we continue this function later (see example for ‘01’ sub-command below). A linear (1st order) fit will be used to obtain a new set of offset and gain correction coefficients for these four (4) channels.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'C'— Sub-command Index 01: Collect Data for a Calibration Point This sub-command has two (2) additional required parameters. Command “C 01 pnt pppp.pppp” ‘C’ is the command letter. ‘ 01’ is the sub-command index (ii) for Collect Data ‘ pnt’ identifies a particular calibration point that will be supplied. It must be between 1 and npts, where npts was a parameter of the previously executed Configure & Start (‘00’) sub-command. ‘ pppp.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Example: ● Supply each of the previously-specified three (3) pressure calibration points to the MultiPoint Calibration function, as was stated in the previous example of the Configure and Start (‘00’) sub-command. Assume that all the affected four (4) channels have differential transducers with the same -5 to +5 psi range. Include at least one pressure point in the negative range of these transducers. “C 01 1 -2.5” “C 01 2 0.0” “C 01 3 5.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'C'- Sub-command Index 02: Calculate & Apply Correction Coefficients This sub-command has no additional parameters. Command “C 02” ‘C’ is the command letter. ‘ 02’ is the sub-command index (ii) for Calculate & Apply NOTE: all parameters are separated by a space.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Example: ● Finish the Multi-Point Calibration function previously started (as indicated by the previous examples of 'C' sub-commands ‘00’ and ‘01’). Calculate new adjustment coefficients, and save them in the non-volatile memory of the module’s transducers. These new coefficients will then be used for all subsequently calculated EU data acquired by the module, until another calibration function is performed in the future.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'C'— Sub-command Index 03: Abort Multi-Point Calibration This sub-command has no additional parameters. “C 03” Command ‘C’ is the command letter. ‘ 03’ is the sub-command index (ii) for Abort. NOTE: all parameters are separated by a space. “A” Response ‘A’ is the acknowledge letter Description: Aborts the Multi-Point Calibration function, if it is currently in progress.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© READ TRANSDUCER VOLTAGES (Command 'V') Purpose: Command Returns, for the specified channels, the most recently acquired raw pressure data, converted to volts directly from the averaged A/D counts. This simple engineering-unit conversion bypasses any usage of the transducer’s factorycalculated coefficients or the final calibration process’s correction coefficients (offset and gain).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Example: ● Send TCP/IP command to 9816 module (via its connected socket) that returns decimal voltage data for internal channels 1, 5, 9, and 13: “V11110” Response contains data for channels 13, 9, 5, and 1 (left to right): “ 4.999999 -4.989500 0.005390 2.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© CALCULATE AND SET GAINS (Command 'Z') Purpose: Command Instructs a module to calculate new gain coefficients, with either full-scale pressure (or a specified pressure) applied to the specified internal channels. These new coefficients update part of the module’s internal calibration coefficient database, used to convert any subsequent raw data (from any of the specified channels) into engineering units data.
Pressure Systems, Inc. Note 98RK-1 & 9816 User’s Manual© The calculated gain values from the latest 'Z' command will be lost when the module is powered OFF. To save these gain terms to each transducer's nonvolatile memory, refer to the Set Operating Options ('w') command (index 09). Example: ● Send TCP/IP command to a 9816 module (via its open socket) to calculate and set gain coefficients for channels 8 through 4. Instruct the module to use 14.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© READ TRANSDUCER A/D COUNTS (Command 'a') Purpose: Command Returns the most recently acquired raw pressure data for the specified channels in averaged signed A/D counts (in the range -32768 to +32767). This simple data bypasses any usage of the transducer’s factory-calculated coefficients or the final calibration process’s correction coefficients (offset and gain).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Example: ● Send TCP/IP command to 9816 module (via its connected socket) that returns decimal raw “pressure” A/D counts data for internal channels 1, 5, 9, and 13: “a11110” Response contains data for channels 13, 9, 5, and 1 (left to right): "32767.000000 -32700.000000 10.000000 16385.000000" Please note that channel 13 is saturated at +full scale and channel 9 is almost saturated at -full scale.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© READ HIGH-SPEED DATA (Command 'b') Purpose: Command Returns the most recent scanned and averaged data from all channels of the module as fast as possible. Data is returned directly in its internal (IEEE singleprecision float) binary form (as per implied format 7).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© DEFINE/CONTROL AUTONOMOUS HOST STREAMS (Command 'c') Purpose: Defines and controls the autonomous delivery of any of up to three concurrent high-speed data streams to the host computer. Such data streams may be delivered “continuously” without bound (until a command explicitly stops them), or be delivered in a “limited” amount (until a pre-specified fixed number of data packets have been sent).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© The maximum rate of any one stream’s delivery is practically limited to the maximum possible scan and data conversion rate of all the module’s channels. Normally, these programmable host streams deliver host data at rates equal to or slower than this natural cycle. For a typical application, the first stream delivers a few channels, at a high rate (as defined by a hardware trigger).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'c'— Sub-command Index 00: Configure a Host Delivery Stream This sub-command is used to configure the parameters of each of the three possible concurrent host delivery streams, one at a time. Following this configuration phase, the stream (1, 2, or 3) may be started and stopped with other sub-commands. The sub-command’s format is: “c 00 st [[[[p]p]p]p]p sync per f num” Command ‘c’ is the command letter.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© internal channels. Following completion of the acquisition (and EU conversion) cycle, the module will also deliver the requested data channels to the host. In this manner, users are provided with highly synchronized data acquisition and delivery from one or more modules.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© NOTE: With the exception of binary format 7, all other formats include a leading space in each datum delivered in each stream packet. The number of stream packets (num) parameter is a positive integer count (specified with 1 to 5 numeric digits as needed). It sets a finite limit on the number of packets delivered in the host data stream. The value 0 for this parameter requests “continuous” output packets for the defined host stream (unbounded).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'c'— Sub-command Index 01: Start Stream This sub-command is used to start the delivery of any previously configured host stream in a module. If the stream started is of “continuous” duration, then it will be necessary to use the Stop Stream sub-command later. Otherwise, the stream will end automatically if a finite number of packets has been specified for it.
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© For periodic hardware-triggered streams, that are never suspended and resumed after being initially enabled, the sequence number may also serve as a “relative” time stamp if the period (in milliseconds) of the hardware trigger is known. If a special sub-command (ii=05) is used to select the content of a stream, other status data may immediately follow the binary stream header and precede the default Pressure EU Data (if selected).
Pressure Systems, Inc. 98RK-1 & 9816 User’s Manual© Command 'c'— Sub-command Index 02: Stop Stream This sub-command is used to abort (or temporarily suspend) the delivery of any previously started host stream in a module, one at a time or all together, whether the stream was “continuous” or “limited” duration.
