Install Jumper onto S1-A on Component Side of Board. Version A Version B Testpoint/Jumper Locations Page 5 IV. COMMANDS FOR ACCESSING EEPROM: NO. command letter index meaning # of bytes 1. R,W 01 Input range or function 1 2. R,W 02 Input/output Configuration 1 3. R,W 03 Decimal point 1 4. R,W 04 Filter time constant 1 5. R,W 05 Reading scale 3 6. R,W 06 Reading offset 3 7. R,W 07 Communication parameters 1 8. R,W 08 Communication bus format 1 9. R,W 09 Communication Data format 1 10. R,W 0A Communication device address 1 11. R,W 0B Communication recog. char. 1 12. R,W 0C Unit of measure 3 13. R,W 0D Gate time 1 14. R,W 0E Debounce time 1 15. R,W 0F Transmit time 2 NOTE: 1. Data (Number of hex digits) = 2 * number of bytes 2. command letter meaning R Read from EEPROM W Write to EEPROM 3. "W" commands should be followed by "Z01" command for new values to take effect. A. COMMAND FORMAT (TRANSMITTING): *[nn]Cxx[data][hh] Note: Data is required if Command Letter is “W” B. RESPONSE FORMAT (RECEIVING): A. Correct response : 1. If unit is in echo mode* (see "BUS FORMAT") : [nn]Cxx[data][hh] *echo mode = unit will send back the command. Page 6 2. If unit is not in echo mode : i. For the commands which require the data to be transmitted by the DRX Signal Conditioner, data is sent in the following formats: data[hh] ii. For the commands which do not require the data: NO RESPONSE B. Error response: 1. If unit is in echo mode: [nn]?ee 2. If unit is not in echo mode: ?ee NOTE : [ ] : Means will be used wherever applicable. * : Is the security recognition character(default is “*”). nn : Is the unit's address in hexadecimal(default is 01). Address may be from 01 to FF. C : Is the command letter ( must be capital ). W : For writing to the EEPROM (requires data) R : For reading from the EEPROM (doesn’t require data) xx : Command index is a hexadecimal number from 01 to FF. data : Is one, two, or three bytes (2,4,6 characters respectively). It will be in hexadecimal format except when command "X" is executed in which case it is in decimal format. hh : Is checksum characters ( Required if Checksum option is on. See “BUS FORMAT”). The checksum is one byte (two characters) that is the simple hexadecimal addition of all the previous bytes, ignoring any overflow. Page 7 ?ee : Special code indicating an error has occurred as: ?43 : Command error ( occurs if command letters and indexes are invalid) ?46 : Format error ( occurs if length of the data or number of characters is not correct ) ?48 : Checksum error ( occurs if checksum is not correct ) ?50 : Parity error ( occurs if parity is not correct ) : Carriage return Note: If Baud rate, Recognition character or address are not correct then the UNIT will not respond. V. DESCRIPTION OF DATA : For the following Bit Pattern. The LSB is always bit 0. Bit numbers are always counted from right to left, with the rightmost digit being bit 0, and the next to the left would be bit 1. 1. INPUT RANGE: This is one byte data (2 characters). This byte will specify input range and other input configurations of each model. Bit pattern for different models : a.
