nRC Change rotation direction for pump n

nRR Set clockwise direction for pump n

nRL Set anti-clockwise direction for pump n

nDOxxxxx,yyy Set dose for pump number n in tachometer pulses (note 3)

nRS Show status for pump number n (note 4)

nZY Show status if pump n STARTed 1 or STOPped 0

nTC Clear tachometer counter

nRT Read tachometer counter

For writing to pump number n display

nCA Clear existing display; followed by:

nCH "Home" cursor; followed by;

nW{text line 1}~{text line 2}@ ( @ = terminator )

1 n = pump number set in Setup. For the command to operate on all

networked pumps simultaneously, use # before the command.

2 1284 tacho pulses per revolution of pumphead rotor on 220rpm version.

3200 tacho pulses per revolution of pumphead rotor on 55rpm version

3 nDOxxxxxxxx where xxxxxxxx is any integer and is the target dose in tacho

pulses. This can be extended to nDOxxxxxxxx,yyy where yyy is a "kick back"

in tacho pulses with a limit of 255 (about 1/5 of a revolution on a 220rpm

drive).

4 A show status command will prompt the 505Du to return a text string of the

following layout:

[pump type] [ml/rev] [pumphead] [tube size] [speed] [cw/ccw] [P/N] [pump

number] [tacho count as a single integer] [stopped/running, 0 /1] [! = delimiter]

eg 505Du 0.7 505l 1.6mm 53.5 CW P/N 1 157810 1 !

5 All networked pumps with the same n will respond to the same command.

6 There should be at least 10mS between consecutive commands

7 When using the # to address all pumps, ensure that it will not generate a

reply, eg nSS, the result will be unpredictable.

This is a typical short program for pump number 2:

OPEN "COM1:9600,N,8,2,CDO,CSO,DSO,OP10000" FOR RANDOM AS #1

PRINT #1, "2SP220" + CHR$(13)

DELAY (command depends on language being used)

PRINT #1, "2GO" + CHR$(13)

DELAY 5000

PRINT #1, "2ST" + CHR$(13)

CLOSE #1

Remote control

Never apply mains voltage across any pins on the 25D socket as

permanent damage, not covered by warranty, will result. Up to 30V may

be applied across pins 4 and 17, and 5v TTL on pins 7 and 5, but no

voltage should be applied across other pins because permanent

damage, not covered by warranty, may result.
