lf the

SW8A does not

respond,

-99999

will

be

loaded

into input locations.

Modules

which do

not respond

when addressed

by

the datalogger

may be wired

or addressed incorrectly.

Verify

that the

address specified in Parameter

2

corresponds

to

the

jumper

setting

and that all

connections

are correct

and

secure.

See the

SDM-SW8A Manual for

104 SDM-CD16

..*

The

SDM-CD16

Control

Port

Expansion

has

16 digitalcontrol

ports

with

drivers. Each

port

can be controlled by

a datalogger or

controlled manually with

an override toggle

switch. Each

port

can

be thought of as

a switch

to

ground;

closed

when

active, open when

inactive. The

primary{unction

is

to activate DC

powered

external

relays,

solenoids, or resistive

loads under datalogger

control.

This

instruction

is not

in

all PROM options.

The

SDM-CD16 is a synchronously addressed

datalogger

peripheral.

.Datalogger

control

ports

1, 2

and

3 are

used

to address the

SDM-CD16

then

clock

out

the

desired

state

of each

of

the

16

control

ports.

Up

to 16

SDM-CD16's may

be

addressed, making it

possible

to control

a

maximum of 256

ports

from

the

first

three

datalogger control

ports.

For

each

Rep, the

16

ports

of the addressed

SDM-CD16

are set

according to 16

sequential

input locations

starting

at

the

input location

specified in

parameter

3. Any non-zero

value

stored

in

an input location activates

(connects

ground)

the

associated SDM-CD16

port.

A

value of zero

(0)

deactivates the

port (open

circuit).

For

example, assuming 2 Reps

and

a

starting

input

location of 33,

OUTPUT

1 through

16

of the

first

SDM-CD16 are set according

to

Input

Locations 33 through 48, and OUTPUT 1

through

16

of

the second SDM-CD16 are set

according to Input Location

49

through

64. See

the

SDM-CD16 manualfor detailed

instructions

and

examples.

connected

to

ports

C1, C2,

and

C3. This

is not

in

There

are 4

per

SDM-

AO4. The

output voltages in millivolts must

be

stored

are

required

for each

SDM-AO4. Every 4 reps

another device at the next higher
