Local Access
To Communicate Through the Local Access Port
Use a computer and a USB Link Kit to communicate locally
with the I/O Flex 6126 to download or to troubleshoot.
Prerequisites
S A computer with a USB port
S A USB Link Kit
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may cause equipment
damage.
S Failure to maintain polarity while using the USB
Link on a computer that is grounded via its AC
adapter may damage the USB Link and the I/O Flex
6126 controller.
S If wary of the integrity of electrical work, and the
computer is running on AC power use a USB isolator
(secured through a third- - party manufacturer). First
plug the USB isolator into the computer's USB port,
then connect the USB Link to the isolator.
1. If using the USB Link Kit with your computer for the
first time, install the USB Link Kit's driver before
connecting the cable to the computer.
a. Put the USB Link Driver CD or WebCTRL install
DVD into the computer.
b. Install the USB Link Driver, accepting all of the
wizard's default settings.
2. Connect the USB Link Kit to the computer and to the
I/O Flex 6126 controller's Local Access port.

Wiring an RS Room Sensor to the I/O Flex 6126
The I/O Flex 6126 supports up to 5 RS sensors on its
BACview/RS sensor port.
RS sensors can be wired to the I/O Flex 6126's Rnet port
in any of the following combinations:
S 1 RS Plus, RS Prow, or RS Pro- - F
S 1–4 RS Standards
S 1–4 RS Standards, and 1 RS Plus, RS Pro*, or RS Pro- - F
* The RS Pro is a thermistor- - based temperature sensor.
To Wire an RS Room Sensor —
1. Turn off the I/O Flex 6126's power.
2. Pull the screw terminal connector from the RS sensor.
3. Pull the screw terminal connector from the Rnet port.
4. Partially cut, then bend and pull off the outer jacket
of the Rnet cable(s). Do not nick the inner insulation.

5. Strip about .25 inch (.6 cm) of the inner insulation
from each wire.
6. Wire each terminal on the I/O Flex 6126's Rnet port to
the terminal of the same name on the RS room sensor.
NOTES:
If using shielded wire, connect the shield wire
