2.1 General

The SDM-IO16 is supplied with two removable mounting brackets that attach to
the ends of the unit, as shown in Figure 1.
The full functions and support for the error checked communications
protocol require an operating system for the datalogger and Edlog
template files that post-dates March 2002. The CR10X and CR23X
with older operating systems and the CR10, CR7 and 21X
dataloggers can use I/O Instruction 104 to set and use the ports for
output only.

CR6, CR800, CR850, CR1000, CR1000X,
CR3000, CR5000, CR10X, and CR23X. (CR10,
21X, and CR7 output modes only.)
12 VDC nominal (9 to 18 V).
600 µA typical standby (All ports HI, no load, not
pulse counting).
Maximum (no output load): 3 mA active with all
16 ports counting pulses at 2 KHz. Above the
quiescent level, power consumption is roughly
proportional to input signal frequency and number
of ports used.
Current drawn from any output must be added to
the quiescent level to give the total current drain.
0/5 V logic level ports compliant with the
requirements of the CS SDM protocol — these are
designed for connection to the datalogger's
control/SDM ports.
-25C to +50C standard

Mounting brackets have two holes at 225 mm
nominal spacing. Mounting screws and plastic
inserts suitable for use with Campbell Scientific
enclosures are also supplied.
