25. SENSOR FOR ALARM2
Write Command: 3a
Read Command: 6e
Interpret: 0 == monitors INPUT2 for ALARM2
1 == monitors INPUT1 for ALARM2
26. ANALOG OUTPUT MULTIPLIER
Write Command: 2f
Read Command: 63
Interpret: For writing, multiply the desired analog output multiplier by 100
10
, and then convert to hexadecimal.
For reading, convert the hexadecimal value to decimal, and then divide by 100
10
. The allowable range
is 0 to 1.00.
0.00 multiplier would be 0
0.50 multiplier would be 50
10
1.00 multiplier would be 100
10
27. LATCH CLEAR
Write Command: 75
Read Command: NA
Interpret: Send this command to reset alarm latches.
28. OUTPUT ENABLE
Write Command: 30
Read Command: 64
Interpret: 0 == OFF
1 == ON
29. SOFTWARE REVISION
Write Command: NA
Read Command: 05
Interpret: Returns revision level of software
30. SET TEMPERATURE READ
Write Command: NA
Read Command: 06
Interpret: Convert the returned hexadecimal value to decimal, and then divide by 100
10
.
31. EEPROM WRITE ENABLE or DISABLE
Write Command: 31
Read Command: 65
Interpret: 0 == EEPROM write is disabled
1 == EEPROM write is enabled
Note: This function is always stored to EEPROM.
Upon a power-up or reset condition the controller performs an initialization of all variables with write
commands and transfers their last written state stored in non-volatile memory (EEPROM) to appropriately
referenced static RAM locations. This action is performed so the controller can run at a quicker pace due
to the slow access of EEPROM. When EEPROM is write enabled, all variables with write commands have
mirror storage of their
communicated value. When EEPROM write is disabled, variables with write
commands are not stored except to the appropriate static RAM locations. With EEPROM writes disabled,
you have the ability to change the run-time values and configuration while not affecting the desired
power-up state. Alternatively, this will also alleviate a possible problem by minimizing the number of
writes to any EEPROM location. (The maximum number of writes that can be made is 1,000,000.)
