Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
CAUTION
When Installing the Unit
• Never plug in nor remove the power supply cord with wet hands, as doing so may cause electric shock.
• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord
itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
• When moving the unit, be sure to remove its power supply cord from the unit. Moving the unit with the power
cord connected may cause damage to the power cord, resulting in fire or electric shock. When removing the
power cord, be sure to hold its plug to pull.
• Do not block the ventilation slots in the unit's cover. Doing so may cause heat to build up inside the unit and
result in fire.
• 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.
When the Unit is in Use
• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal
injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.
• Use the dedicated AC adapter for the unit. Note that the use of other adapter may cause a fire.
• Contact your TOA dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of
time, a fire or damage to the unit may result.
• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically.
In addition, insert the plug in the wall outlet securely.
• Unplug the power cord from the unit for safety purposes when cleaning or leaving the unit unused for 10
days or more. Doing otherwise may cause a fire or electric shock.
C-IF500 complies with Part 15 of the FCC Rules.
Note
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Modifications
Any modifications made to this device that are not approved by TOA Corporation may void the authority
granted to the user by the FCC to operate this equipment.
2. GENERAL DESCRIPTION
The TOA C-IF500 Interface Unit is a splitter for control signals to be used when controlling 32 or more TOA
Combination Cameras connected to the TOA C-RM500 Remote Controller.
3. FEATURES
• Can split the C-RM500 Remote Controller's control signal into 4 signals.
• Can convert the C-RM500's control signal level into the RS-232C signal level.
• Connecting the unit between the C-RM500 and the Combination camera permits star connection between
the Remote Controller and camera.

is used in the OFF position depending on the
connection method.
Connect the AC adapter to this terminal.
6. 12 V DC power input terminal *
Please connect with the power supply other than
the AC adapter by the cable that attached the
supplied clamp filter.
Refer to p. 6 for details.
10. RS-232C terminal [SLAVE/RS-232C]
Converts the data received at the Master
Connection Terminal into the RS-232C signal
level and sends out the converted signal. The
RS-232C Terminal also converts an input signal
to the RS-232C terminal into the RS-485 control
signal, and outputs the converted signal from the
Master Connection Terminal.
