IX. SETPOINTS
The M2000 offers functionality which allows the user to store and recall output levels (set-
points). Additional functionality allows the user to automatically step through a number of set-
points at a configurable interval. Up to 9 setpoints can be programmed for each range.
A. Setting a Setpoint
1. To set a setpoint go to the desired range and enter the desired output value.
2. Once you have entered the output value press the key followed by the
key.
3. Select the number of the setpoint in which the present output value is to be stored.
B. Recalling a Setpoint
1. To recall a setpoint press the key followed by the key.
2. Select the number of the setpoint you wish to recall.
C. Auto Setpoints
1. To initialize auto setpoint functionality, press the key followed by the
key.
2. Select the number of setpoints to be recalled. Setpoints step up from setpoint one to the
setpoint selected and then down.
3. Select the interval (in seconds) between setpoints.
NOTE: During auto setpoint mode the can be used. Pressing any other
key will cause the unit to exit this mode.
X. REMOTE INTERFACE
Setting up the RS-232 Port for Remote Control
The M2000 is fully programmable over an RS-232 link with a PC.
The RS-232 cable length for the port should not exceed 15 meters (50 feet), although longer
cable lengths are permitted if the load capacitance measured at a connection point (including
signal terminator) does not exceed 2500 pF.
RS-232 Port Setup Procedure
Serial parameters are fixed with the values shown below:
· 9600 baud
· 8 data bits
· 1 stop bit
· no parity
· Xon/Xoff
· EOL (end-of-line) character CR (Carriage Return)
A typical connection is shown in Figure 5. Note the use of a null modem cable for connection.
