Campbell Hausfeld SDM-CD16AC Manual Do Utilizador

CDCtrl(1) will be sent to port 1, the value held in CDCtrl(2) will be sent to 
port 2, etc. The value held in CDCtrl(32) would be sent to port 16 on the 
second SDM-CD16AC. 

Reps:  The Reps parameter is the number of SDM-CD16AC devices that will 
be controlled with this instruction.  

SDMAddress:  The SDMAddress parameter is used to define the address of 
the CD16AC that will be controlled with this instruction. Valid SDM addresses 
are 0 through 14. Address 15 is reserved for the SDMTrigger instruction. If the 
Reps parameter is greater than 1, the datalogger will increment the SDM 
address for each subsequent device that it communicates with. 

CRBasic dataloggers use base 10 when addressing SDM devices. 
Edlog programmed dataloggers (e.g., CR10X, CR23X) used 
base 4 for addressing (see Table 2).
