GMC-I Messtechnik GmbH DP BASE DIGITAL PRESSURE METERS The Model DP Base is a Microprocessor based Digital Pressure Meter. It measures both gas and liquid pressures and provide multiple engineering unit displays for the results. The following are highlights of some of the main features. Main Features: -13.50 TO 100.
LAYOUT This section looks at the layout of the DP Base and gives descriptions of the elements that are present. DP Base Layout RS-232: ⅛” Stereo Jack Power: 2.
DISPLAY INDICATORS Several indicators are provided to identify the current mode and/or status. PRESSURE UNITS – Pressure units are indicated by an identifier bar. The RANGE key will toggle the pressure units among PSI, mmHG, inH2O and cmH2O. The following is a breakdown of the available pressure units and the measurement range for each: Identifier Bar (flashing) Pressure Units Range PSIG -13.50 to 100.
KEYS Several tactile-touch keys are provided for system operation. – The function of this key is dependent on the Current Operating Mode as follows: POWER OFF – If this key is pressed while the power is turned OFF, the power will be turned ON PRESSURE MEASUREMENT – If this key is pressed while the pressure is being displayed, the Setup Mode will be entered. SETUP MODE – Pressing this key while in the Setup Mode will sequence the display through the available parameters.
– The function of this key is dependent on the Current Operating Mode as follows: PRESSURE MEASUREMENT – If this key is pressed while the pressure is being displayed, the unit will display the maximum pressure detected since the capture register was last reset. SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed setting will increment. Pressing and holding this key will cause the rapid automatic incrementing of the displayed setting.
SETUP MODE The Setup Mode allows the user to adjust the configuration of the meter. The Setup Mode is entered by pressing The ON/SETUP key when the unit is on. The parameter and the current value will alternately flash in the display.
COMMUNICATIONS Since the meter does not handle a great deal of data, the RS-232 communications link has been optimized to allow the user, through very simple instructions, to control and request data from the meter. Refer to Specifications section for RS-232 Settings (Baud, etc). Data transmitted/received is in standard ASCII format, and all numerical values are in BCD format. All commands sent to the unit should be terminated with a “Carriage Return” character ( or in hexadecimal, 0x0D).
Examples: Data Sent W172 Data Returned W172 W1700002 W1700002 W01100 U - UPLOAD W01100 ?? Meaning Echo of Command Sent (Set Pressure units to “inH2O”) Echo of Command Sent (Set Pressure units to “inH2O”) Echo of Command Sent Invalid Command Response (Location 01 is Read Only) The UPLOAD command allows the user to read all of the selected device data from locations 1 through 16 with a single command.
The CANCEL command is simply a way to re-establish proper control, should a communications error occur or an incorrect command be transmitted. For the most part, an incorrect command will simply be ignored and the meter will return to listening for future commands. However, a prior command may be cancelled midstream by transmitting the CANCEL command anytime. X - CANCEL Usage: X This command does not require a carriage return, nor will it acknowledge with a carriage return.
