Configuring the Excel 10 Remote
Input/Output Device (RIO)
Description
The W7761A Excel 10 Remote Input/Output Device (RIO) is a
LonMark compliant device designed to monitor and control
HVAC equipment, lighting, and other miscellaneous loads in a
distributed network.
Usage
In this version of the wizard, only the Excel 15 W7760A
Building Manager uses the RIO.
Application
The RIO communicates with other controller nodes,
monitoring devices, and engineering tools using the
LonWorks Bus. RIOs provide inputs (analog and digital) and
outputs (digital) to any node on the LonWorks Bus.

Purpose
To configure RIO inputs and outputs.
Configuration Parameters
• Six analog inputs – four are resistive type and two are
current or voltage
• All resistive inputs are temperature inputs
• Current or voltage can be humidity, airflow, or pressure
sensors
• Four digital inputs
• Eight digital outputs, which can be discrete, modulating, or
floating
RIO devices do not have equipment control or zone option
parameters, only hardware points. The next two sections
describe the options for configuring the RIO:
RIO Inputs
Use Table 50 to configure the RIO inputs.
Purpose
Configuration of six Analog Inputs and four Digital Inputs of
RIO. Specify up to six analog inputs (four resistive and two
voltage) and four digital inputs.
Mode
Configuration can be performed with the wizard Off-line or
On-line.
Procedure
1. Click the Input_pane button on the left pane to open the
Input Configuration page.
2. Enter information into available fields.
3. Click Commit to save the settings or Reset to revert to
the last saved settings.
4. Click Next to display the Output Configuration page.
RIO Inputs fields
RIO Outputs
Use Table 51 to configure the RIO outputs.
Purpose
Control points through the RIO using the outputs. Configure
up to eight outputs.

Digital Inputs
1 through 4
Select ACTIVE_SHORT or ACTIVE_OPEN.
For each Digital Input configured, specify
MAINTAINED or MOMENTARY.
• Maintained contact closure
A maintained contact closure is where
the monitored contact input changes
condition and remains.
• Momentary contact closure
A momentary contact closure is where
the monitored contact input only needs to
stay in one condition for 1 second
minimum.
DI1-4 Name After configuring a digital input, enter a
descriptive name (up to 18 characters).
