[. . . ] REMOTE OPERATION 4. 3 COMMANDS All PPC2 AF commands are ASCII strings. All commands must be terminated with the correct terminating characters (see Section 3. 4. 4. 3). The user must wait for the PPC2 AF to reply before sending another command. All replies from the PPC2 AF are ASCII and are terminated with the designated terminating characters. 4. 3. 1 COMMAND LIST Send a command string out of the PPC2 AF COM2 port. Read the current atmospheric pressure Read or set the configuration of the COM1 or COM2 port. Read or set the user reference pressure transducer calibration information. Set a new target pressure & use only the fast speed to reach the target. Set a new target pressure & use only the slow speed to reach the target. Read or set a flag that is cleared by a "Not Ready" condition. Read or set the pressure display resolution for the current transducer and range. Save changes made to the user calibration of the reference pressure transducer. Read the PPC2 AF software version. # ABORT ATM COMn(=) DATE(=) DF= DP= DRV DS ERR HEAD(=) HS(%)(=) IF= IP= IS= LOCAL MEM MODE(=) PCALd, r(=) PR PRR PS= PSF= PSS= RANGE RATE READYCK(=) REMOTE RES RESET RETURN SAVECAL SN SR SS%(=) STAT TIME(=) TP UCOEF(=) UL(=) UNIT(=) VAC(=) VENT(=) VER Page 57 © 1998 DH Instruments, Inc. PPC2 AF OPERATION AND MAINTENANCE MANUAL 4. 3. 2 ERROR MESSAGES The PPC2 AF will always reply to a command. If the command is incorrect or contains invalid data, an error number will be returned in the form "ERR# n" where n is an integer number that represents a specific error. Here is a list of the possible errors numbers and the error description for each: REPLY ERR #0 ERR #2 ERR #3 ERR #4 ERR #5 ERR #6 ERR #7 ERR #8 ERR #9 ERR #11 ERR #12 ERR #13 ERR #14 ERR #18 ERR #21 ERR #22 ERR #23 ERR #25 ERR #26 ERR #27 ERR #28 "OK" "Text argument is too long" "User defined coefficient cannot be 0" "External device not detected" "External device improperly configured" "Numeric argument missing or out of range" "Missing or improper command argument(s)" "External device timeout error" "Unknown command" "Command missing argument" "System overpressured" "Text detected in numeric field" "User unit not defined" "Command not yet available" "User device not defined" "Pressure is not stable" "Option not available or installed" "Transducer out of calibration" "COM port failed to initialize" "Internal device#1 timeout error" "Internal device#2 timeout error" DESCRIPTION The user may retrieve the error message for a previous command error by using the "ERR" command. © 1998 DH Instruments, Inc. Page 58 4. REMOTE OPERATION 4. 3. 3 # Purpose: Syntax: Arguments: Remarks: COMMAND SUMMARY To allow the host PC to communicate with a device connected to the PPC2 AF COM2 port. The PPC2 AF COM2 port can be used to communicate to another RS-232 device (such as another PPC2 AF). This allows the user to use one COM port or IEEE port on the host computer to communicate with the PPC2 AF and another device. A carriage return and a line feed (<CR><LF>) are added to the string. After this command is issued, the PPC2 AF will reply back the first string received by the PPC2 AF COM2 port that is terminated with a carriage return. Prior to using this command, you must ensure that the PPC2 AF COM2 port is correctly set up to communicate with the device. This assumes that a second PPC2 AF's COM1 port is connected to the PPC2 AF COM2 port. This example gets the version of the second PPC2 AF: Command: "#VER" Reply: "DH INSTRUMENTS, INC PPC2 AF VER1. 00" None. Example: See Also: ABORT Purpose: Remarks: Example: See Also: ATM Purpose: Syntax: Arguments: Remarks: Example: See Also: Stops an active pressure generation. [. . . ] When operating from the setup-driver screen (see Section 3. 3. 4), pressing enter will allow the operating mode of the drivers to be set. A momentary driver will change state while the corresponding driver number on the keyboard is being pressed. In toggle mode the driver state will toggle each time the corresponding key is pressed. However, the total output of all the activated drivers cannot exceed one Amp. [. . . ]
