FOR STAND-ALONE MODE
Note
Two modes of operation are made available for the SX-2000CI and SX-2000CO: Normal mode
where the unit operates within the SX-2000 system and Stand-alone mode where the unit
operates independently of the SX-2000 system.
This book provides instruction when the SX-2000CI and SX-2000CO are used in stand-alone
mode.
When using them in normal operation mode, refer to the instruction manual enclosed with the
SX-2000SM System Manager of the SX-2000 series.

When Installing the Unit
• Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the
unit. Using a voltage higher than that which is
specified may result in fire or electric shock.
• Since the unit is designed for in-door use, do not
install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal
injury. Also, when it gets wet with rain, there is a
danger of electric shock.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately switch off the power, disconnect
the power supply plug from the AC outlet and
contact your nearest TOA dealer. Make no further
attempt to operate the unit in this condition as this
may cause fire or electric shock.
· If you detect smoke or a strange smell coming
from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
qualified service personnel.
• Do not place cups, bowls, or other containers of
liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire
or electric shock.
When Installing the Unit
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.
• SX-2000CI and SX-2000CO are designed
exclusively to be mounted in an equipment rack.
Be sure to follow the instructions below when rack-
mounting the unit. Failure to do so may cause a fire
or personal injury.
· Install the equipment rack on a stable, hard floor.
Fix it with anchor bolts or take other arrangements
to prevent it from falling down.
· When connecting the power cord of the DC
power supply panel for the SX-2000CI/CO to an
AC outlet, ensure that the total load current never
exceeds the AC outlet’s allowable current
capacity.
· The supplied rack-mounting screws can be used
for the TOA equipment rack only. Do not use
them for other racks.
When the Unit is in Use
• Use the specified DC power supply unit AD-011 or

2. GENERAL DESCRIPTION
The SX-2000CI Control Input Unit is equipped with 32 control input channels, and the SX-2000CO Control
Output Unit with 32 control output channels, allowing various operations to be performed by connecting
external equipment.
One each of the SX-2000CI and SX-2000CO must be used in combination. Connecting the CI/CO link data
terminals of each unit to one another permits the contact data of multiple channels to be transmitted to the
remote locations with simple wiring.
The front-mounted indicators of each unit show the control input status or control output status.
The SX-2000CI and SX-2000CO are 1U-size* units that can be mounted in an EIA equipment rack. It has 2
power supply inputs, one of which can be connected to a backup power source to protect against power
failures. The SX-2000CI has a function to supply a stabilized 24 V DC.
Priority control of the control input can be performed by making settings at the SX-2000CI.
*1U size = 44.5 mm (standard size)

4. CONNECTIONS
4.1. Removable Terminal Plug Connection
Notes
• Do not use a micro screwdriver. Sufficient torque is not given to the screws when tightening them, and
connections may not be secured.
• Avoid soldering stranded or shielded cable, as contact resistance may increase when the cable is tightened
and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.
• When connecting 2 cables or a shielded cable to a single terminal,
use a ferrule terminal with an insulation sleeve to crimp the cables
because such cable conductors could become loose.
Recommended ferrule terminals for signal cables
(made by Phoenix Contact)
Recommended ferrule terminals for power supply cables
(made by Phoenix Contact)
Crimping tool: CRIMPFOX UD6-4 (made by Phoenix Contact)
Wiring procedures
Procedures below are for the removable terminal plug with fixing screws.
Step 1. Wiring the supplied removable terminal plug.
1-1. Loosen the terminal screws to insert the wire.
1-2. Tighten the terminal screws.
Ensure that the wire does not break free
when pulled. If the wire does pull free, repeat
the connection procedure from the start.
Step 2. Insert the wired terminal plug into the
corresponding terminal block in the unit's rear
panel.
Step 3. Tighten the fixing screw.
Notes
• Do not reverse Steps 1 and 2 above. Force is applied to the connected receptacle pins while tightening the
terminal screw and they may be damaged, resulting in bad connector contact.
• When detaching the terminal plug, pull it straight out. Pulling it out at an angle may cause the terminal plug
or terminal block to break.

4.3.3. Connection for Example 3
Both the SX-2000CI and SX-2000CO can be driven by connecting 2 power supply panels to the SX-2000CI
only.
Connect the DC power input terminals of the SX-2000CI to those of the SX-2000CO and the CI/CO link data
terminals of the SX-2000CI to those of the SX-2000CO via the RM-200RJ Terminal Unit (optional).
(See the next page.)
When installing the SX-2000CI and SX-2000CO separately from each other, the power supply panel does not
need to have at each unit by making connection in this manner.
Note
When connecting the power supply panel to one of the equipment, be sure to connect it to the SX-2000CI
side.
If it is connected to the SX-2000CO side, the maximum cable length between the SX-2000CI and SX-2000CO
may be reduced.
[Maximum cable length]
The maximum cable length between the SX-2000CI and SX-2000CO varies depending on the conductor
diameter of the CPEV cable used between the RM-200RJs.
The following table shows the conductor diameter of the CPEV cable vs. maximum cable length when the
power is supplied from the SX-2000CI side.

Notes
• If you change the DIP switch setting, be sure to press the Reset key inside the protective cover to restart the
SX-2000CI.
• Control inputs act as such that they have been closed in numerical order of terminal numbers after the SX-
2000CI is switched on or restarted with these inputs closed in any order.
In this case, the highest priority is assigned to the control input of the largest terminal number when the
priority control type is "Last-in-first-out," and to the control input of the smallest terminal number when "First-
in-first-out."

5.2.1. No priority control (DIP switch 3: OFF, DIP switch 4: OFF)
In this mode, priority control is disabled. (Factory default)
For example, closing the control input 2 while the control input 1 is closed causes
the control output 2 to close simultaneously while the control output 1 remains
closed.
Control inputs 3 – 32 operate in the same manner.

For example, closing the control input 1 while the control input 2 is closed causes
the control output 2 to open.
Opening the control input 1 causes the control output 2 to close.
