SWITCH FUNCTIONS: There are five switches located behind the front lens of the model DP-7600. The front panel switches appear as shown below. The text located at the top half of each switch (i.e., NORMAL, PEAK, RUNOUT, TARE, ABS/REL) indicates that particular switch’s function when the unit is in data acquisition and display mode.

LED INDICATORS: Limit 1 Illuminates when the display reading exceeds the set limit, and in the setup mode when establishing the limit. Limit 2 Illuminates when the display reading exceeds the set limit, and in the setup mode when establishing the limit. Limit 3 Illuminates when the display reading exceeds the set limit, and in the setup mode when establishing the limit.
to advance to the next parameter. At any time during the setup sequence the EXIT switch can be pressed to leave the setup mode and save the current settings. If the setup sequence is completed the unit will save all settings and automatically return to data acquisition and display mode.
Once the proper baud rate is selected press the ENTER switch to advance to the next setup. ECHO SETUP The model DP-7600 can be programmed to automatically re-transmit (echo) characters received on its serial communications input. A value of one enables the echo feature; conversely, programming a zero will disable it.
LEGEND SETUP The DP-7600 can append a user selectable engineering units string to read- ings transmitted from the unit. This feature allows direct terminal readout in engineer- ing units, or easier unit identification in multi-unit applications. Program the legend number to the number corresponding with desired units as shown in the table below.
CALIBRATION: The calibration mode is entered by pressing the Normal [Enter] and ABS/REL [Exit] switches simultaneously. Note: This is the only method to check or change the calibration of this unit externally. PROTECTION CODE Before any calibration can be performed on the unit a unique security code must be entered.
Both RS232 and RS485 serial communication options are available for the DP-7600. The baud rate is user selectable, and can range from 300 to 38.4K baud. The unit uses a N,8,1 character data format (no parity, 8 data bits, 1 stop bit).
: “BYE ad 0[CR]” Note: Remember [CR] represents a carriage return character. The following is a list of the serial commands available on the DP-7600. Each com- mand string is shown in quotes, a parameter/number field is represented by X (first) or Y (second), the sign, where needed, is shown as a lower case s(s).
The address enable command, in conjunction with the address disable command, can be used to network multiple DP-7600 units. Once a unit’s address has been enabled it will respond to all incoming commands until the unit’s address is disabled. When the address enabled command is executed by a DP-7600 it responds with “HELLO ae...
(since contention could result in scrambled data at the printer). To compensate for this, the model DP-7600 allows unit to “take turns” on the same serial bus. This is done by enabling transmission of a special non-printable character at the end of a reading string;...
READING MODE: “PV X[CR]” The display reading mode can be set using this command. X = 0: Display is set for reading only X = 1: Display is set for peak X = 2: Display is set for runout ABSOLUTE OR RELATIVE “AR X[CR]” Allows changing of the display mode between absolute and relative.
Example: Assume we want a high limit, normal (reading), active on channel one; then, YY = 01 OR’ed 08 = 09 HEX (NOTE: unlike most serial command parameters, this is not ASCII). REMOTE INPUTS: Seven logic level, active-low, remote inputs are located on the rear of the unit for inter- facing to programmable logic controllers etc..
DP-7600. Also assume that the excitation required 10V; therefore, the full-scale input to the unit will be 5mV at 10,000 pound, and the sensitivity switches located on the rear of the DP-7600 should be set for 5.1mV full-scale (S1 - S3 open).
