When using the Binary protocol (see parameter#27), valid values are from 1 to 255.
When using one of the Allen Bradley protoccols, valid values are from 0 to 254. No unit
may have a value of 255, since that is the address used for general broadcast functions.
Each unit on an RS-422 link must have a unique I.D. The default I.D. number is 1.
Using 1 as one of the unit I.D. numbers may cause an addressing conflict if a unit
returns to its default values, so it may be advisable to start the addresses number 2.
Entering an illegal address causes an error code 08. Press PGM/CLR to clear it.
This parameter may be changed while running, but consider the consequences on the
communications system.

#18 BAUD RATE

#18 #18 BAUD RATE
Set the Baud Rate for serial communications. Valid values are 3 (for 300 baud), 6 (for
600), 12 (for 1200), 24 (for 2400), 48 (for 4800) and 96 (for 9600).
After setting the baud rate, the serial communications of the host must be set to 8 data
bits, NO parity, and 1 stop bit (8-N-1). These settings in the DIGIMAX
Entering an incorrect baud rate generates error code 10. Press PGM/CLR to clear it.
#19 #19 LOCAL / REMOTE / KEYLOCK LOCAL / REMOTE / KEYLOCK

Enter 0 for LOCAL (keypad) operation.
Enter 1 for REMOTE. The front panel LED will stay lit until LOCAL control is restored.
Enter 2 for KEYLOCK, which is LOCAL/REMOTE controlled through the parameters.
TO RETURN TO LOCAL ONCE THE DIGIMAX
PRESS THE KEY SEQUENCE [ALT] [CODE] [UP] [ENT] TO RESTORE LOCAL CON-
TROL. The code may be either the operator or the maintenance access code.
This parameter may be changed while running.
#20 A TO D TRIM SETPOINT #20 #20 A TO D TRIM SETPOINT A TO D TRIM SETPOINT A TO D TRIM SETPOINT
#20 #20 A TO D TRIM SETPOINT
This parameter sets the gain of the A to D input (TB2 terminals 17+ and 15-) when the
input is used as an analog trim input. When the analog input is 5 VDC, the trim is zero. The
voltage difference above or below 5 VDC (0 VDC min, 10 VDC max) is multiplied by 1/5th
of the number in parameter # 20 and added or subtracted to the SETPOINT.
Parameter #26 must be set to 1 to enable the AtoD input as a trim input.
#21 #21 OPERATOR PASSWORD OPERATOR PASSWORD
#21 OPERATOR PASSWORD #21 #21 OPERATOR PASSWORD OPERATOR PASSWORD
This is the code given to the operator for access to the parameters. It may be any
number from 0 to 99999. The number may be from one to five digits, and leading zeroes do
not need to be entered. This parameter may be changed while the unit is running.
#22 #22 A TO D LOW ENGINEERING UNITS A TO D LOW ENGINEERING UNITS
#22 A TO D LOW ENGINEERING UNITS #22 #22 A TO D LOW ENGINEERING UNITS A TO D LOW ENGINEERING UNITS
The input at terminals 15 (-) and 17 (+) on TB2 may range from 0 to +10 VDC. This
parameter sets, in engineering units, what the effect of the 0 VDC level will be.
This parameter may be changed while the unit is running.
