IV. Remote Connections
(continued)
Contact Closure/Latching Switch: The unit will power up when the contacts are closed, and
power down when the contacts are open. Connect the two wires from the contacts or switch to
Pin 1 (Contact Closure) and Pin 2 (Contact Closure / Applied Voltage +).
Outlet control requires a combination of Axess Ready (AR) control via IP and Remote Turn-
On/Off (RT) control via hard-wired connection. The following table will detail the LED and
outlet states during various operating conditions.

External LED Connections
The CM-X-AR products are able to drive external LEDs or other signaling devices through their 12V
DC output, which can provide up to 10mA of current. External LEDs connected in this way will be
On when the unit’s AC receptacles are On, and Off when they are Off. When connecting LEDs to
the 12V output, a series resistor is required. For example, many LEDs work well with 10mA of
current, so a 1K
Ω resistor is usually a good choice. If more than one LED is required, then use a
separate series resistor for each LED. For example, two external LEDs, each with a
2kΩ series
resistor, could be powered from one unit at 5mA each.
Connect each LED anode to “Remote LED +” through a resistor, and the cathodes to
“Remote LED -”.
Auxiliary Relay Contacts
The auxiliary relay contacts, Pins 6 & 7, provide a way to cascade units or to provide
confirmation feedback to a central controller. When the receptacles are On, the aux relay
contacts are closed. There is a 1 second delay before the aux relay closes, which allows time for
the SurgeX Inrush Current Elimination (ICE™) circuit to operate. This short delay in combination
with the SurgeX ICE™ makes it unnecessary to sequence the power to several large loads
(such as amplifiers) because of inrush current. SurgeX CM-X-AR products, when cascaded, can
turn on a bank of large amplifiers with no inrush current, and therefore no risk of tripping a circuit
breaker.
To cascade two or more CM-X-AR products, connect the aux relay contacts of one unit to the
contact closure input of the next unit. To provide confirmation feedback, connect the aux relay
contacts to an input on the central controller. The relay contacts are rated for 1 amp at 30 V DC.
