Programmable Option– RS232 Commands and Responses
(Continued)
timeleft? queries time remaining in active step
response: xx:xx:xx where hr:min:sec
number? queries number of steps in program
response: n where n = 1 to 8
step? queries step being programmed (Not the active step)
response: n where n = 1 to 8
time? queries time in program step ( Not the active step )
response: xx:xx:xx where hr:min:sec
travel? queries direction of travel in programmable step (not active step)
response: I or W where I is infusion, and W is withdrawal
Note: Prompts > or < indicate direction of active step
rateb? queries beginning rate
response: nnnnn uuu where nnnn is . , 0 to 9uuu is
µl/m, µl/h, ml/m. ml/h
ratef? sets finish rate
response: nnnnn uuu where nnnnn is . , 0 to 9
uuu are units µl/m , µl/h, ml/m, ml/h.
portout? queries status of output TTL pins 1 and 6
response HH, HL, LH, LL
pause? queries whether pause
response: Y or N where Y is yes, N is no
loops? queries whether loops in program
response: Sn:x Sn:x where Sn is the step number containing
a loop x is the number of loops remaining
to be executed (counts down)
loop? queries loop status in the step
response: Y or N where Y is yes, N is no
loopto? queries step number to which program loops (not available if
no loops)
response: n where n = 1 to 7
loopcnt? queries number of loop repeats (not available if no loops
programmed)
response: n where n = 1 to 100
NOTE:
a) It is important to save each step before programming next step
b) Only two loops are permitted, therefore recommend to query number of loops in an
existing program before modifying the program. If loops are present it will be necessary
to delete an existing loop before a new loop can be programmed.
