Execution control commands

Operating instructions
Execute or skip next command based on aux inputs (x)
Execute the next command (or skip) based on the auxiliary inputs.
Arguments:
Note: Auxiliary inputs are internally pulled high. Thus, if left floating, they will be
high.
The [x] command, in conjunction with the [e] command, can be used as an
IF...ELSE, IF...ELSE statement based on the auxiliary TTL inputs. This is espe-
cially useful in standalone operation.
Example: switch between strings based on input states
The example below allows a C3000/C3000MP in standalone mode to
switch between three modes of operation depending on the states of Input
1 and Input 2. The pump is configured to AutoRun string 0 on power-up. (For
more information on storing strings and using AutoRun, see "Using
EEPROM" (page 76).)
• If Input 2 is low and Input 1 is high, [e1] will be executed. Thus, the pump will
aspirate/dispense cycle 50 increments.
• If Input 2 is high and Input 1 is low, [e2] will be executed. Thus, the pump will
aspirate/dispense cycle 1000 increments.
• If none of the above states of Input 2 and Input 1 are realized, [e3] will be exe-
cuted. The pump will aspirate/dispense cycle a full stroke, 3000 increments.
Note: Using the [e] command in a string will force a jump to the specified
string. It will not automatically return to the departure point once the
“jumped to” string has completed.
The following four strings are programmed into the EEPROM locations 0, 1,
2, and 3 (the commands s0, s1, s2,and s3 store their strings in locations 0, 1,
2, and 3 respectively):
[s0Zx1e1x2e2e3R]
[s1gIA50OA0G0R]
[s2gIA1000OA0G0R]
[s3gIA3000OA0G0R]

1. Input 1 is located on connector JP3 pin 7, and Input 2 is on JP3 pin 8.
Input 1 Action
0 Low Low Will execute next command in the string buf-
fer if Input 2 and Input 1 are held low.
1 Low High Will execute next command in the string buf-
fer if Input 2 and Input 1 are set as indicated.
2 High Low Will execute next command in the string buf-
fer if input 2 and Input 1 are set as indicated.
3 High High Will execute next command in the string buf-
fer if Input 2 and Input 1 are both high.
