Personal Environments
Data Input/Output Cable
The Personal Environments Data Input/Output
Cable (PE-DATA-IO) (Figure 1) connects the
Fan and Electronics Unit (FEU) to an external
controller through individual monitor and control
signals, which are available at the Data I/O
socket on the FEU Connection Panel (Figure 2).
The Data I/O Cable may be used with either the
Supplied Air or Circulated Air Personal
Environments systems, which do not have a
Metasys network connection. The Data I/O
socket is not available with Metasys networked
Personal Environments systems.
!
CAUTION: Connecting multiple
Personal Environments
points/objects on a single
wire to a single external
controller may result in
ground loops and signal
degradation, which could
detrimentally affect the
operation of the Personal
Environments systems.
The Data Input/Output Cable is an
eight conductor cable. One end is terminated in
an RJ 45 plug, which is connected to the Data
I/O socket. The other end of the six foot cable is
not terminated. The wires are connected to an
external controller for monitoring and control. It
is not necessary to use all monitor outputs or
control inputs available. For those outputs or
inputs used, it is necessary to connect each
point/object and the common ground to a
separate input or output on the external
controller.

Installation
To install the Data I/O Cable:
1. Remove the Data I/O Cable from the
package and inspect for plug or cable
damage.
2. Note that the wire color codes of the Data
I/O Cable may vary; therefore, before
connecting the cable, ensure that the proper
signal to wire relationships are established.

3
Connect the output or control input wires for
the signals to be monitored or controlled to
their associated external controller
inputs/outputs (Table 1). Connections must
be consistent with good wiring connection
practice.

Unplug the Personal Environments system
from the utility power outlet and connect the
Data I/O Cable RJ 45 plug into the Data I/O
socket in the FEU Connection Panel.
Testing the Cable
To test the Data I/O Cable:

(Connector Type: RJ 45; 8-conductor)
1. Plug the Personal Environments system into
an appropriate utility power outlet.

3. If temperature (Supplied Air system only),
fan speed, or radiant heat are monitored,
observe that the voltages change as
indicated in Table 1.
4. If the Occupancy Sensor is monitored,
observe that the occupancy contact closes
when occupancy is sensed as indicated by
the status light on the User Control Unit.
5. If Occupancy Override or Precondition
control signals are connected, observe that
the proper action takes place when 10 VDC
are applied to these inputs.

Note:
The “B” appended to the Personal
Environments product code means the
product can be ordered in bulk
quantities. The specific number of items
is declared in the product code
description. For example, “Bulk 25”
means that when the product is ordered,
exactly 25 items will be in the bulk
package. The option was provided so
that the job site trash would be
minimized for new and retrofit projects.
