Configuring Control Port Contact Closure Operation
The Rules panel in the Web-GUI can be used to configure control port and logic inputs and
outputs. Codec 'rules' configure events based on specific codec actions. Typically rules are based
on a change in the state of a physical GPIO control port, or a Tieline or WheatNet-IP logic IO, or a
codec program being connected or disconnected. Rules can only be created with the Web-GUI
while the codec is disconnected. There are two ways to create rules in the HTML5 Toolbox Web-
GUI:
1. The Rules panel, or
2. The Program Manager panel.
Rules for connecting or disconnecting a program are configured in the Rules panel. Rules for
connecting or disconnecting an audio stream are configured in the Program Manager panel.
Important Note: A non-WheatNet-IP Tieline codec can be configured to trigger a logic IO
in a Tieline Genie Distribution and Merlin PLUS WheatNet-IP codec, as well as 4 physical
CONTROL PORT GPIOs. The codec has:
· 4 physical CONTROL PORT GPIOs.
· 7 Tieline and WheatNet virtual inputs (1-7). Note: Virtual inputs 5-7 can be activated
by pressing the F1 button and SOURCE buttons 1-3.
· 64 Tieline virtual logic outputs. Note: Tieline logic IOs (LIOs) are only supported
between Genie, Merlin, ViA and Bridge-IT IP codecs.
· 64 virtual WheatNet logic outputs available in Genie Distribution and Merlin PLUS
WheatNet-IP codecs. These allow Tieline WheatNet-IP enabled codecs to activate
functions across a WheatNet-IP network.

Configuring RS232 Data
When Data is enabled the codec can be connected to external devices and transport RS232 data
using the CONTROL PORT I/O on the left side panel of the codec. It is important to configure two
settings:
1. Enable serial port flow control within the codec. Flow control regulates the flow of data
through the serial port. If disabled, unregulated data will flow and some may be lost.
2. Match the serial port baud rate to the rate used by the device connected to the codec
CONTROL PORT I/O. Ideally the settings on both codecs should match, or you could
encounter data overflow issues.
To adjust these settings:
1. Press the HOME
2. Navigate to System and then tap RS232
3. Tap Baud Rate to select from the baud rate options.
