TESIRA EX-LOGIC
The Tesira®EX-LOGIC is a half-rack logic box for use with Tesira SERVER and SERVER-IO devices. The
EX-LOGIC provides both logic inputs and outputs and, through software, can be congured as a control
interface. There are 16 total connections that can be used as inputs or outputs. 12 of the connections are
designed as logic connections only and will accept contact closure or 5V TTL when used for logic or sink a
maximum of 40V/300mA per output. The remaining four connections can also be used for logic connections
or asvariablevoltagecontrol inputs(e.g. interfaceto apotentiometer). Additionally, any ofthe 16connections
can be congured for direct LED driver capability. The EX-LOGIC also provides a serial port for the output
of command strings that can be used to send action commands to other equipment in the system. The
EX-LOGIC communicates with the Tesira AVB network for audio networking, conguration and control,
and is powered by PoE.
BENEFITS
• Logic interface allows Tesira to control or respond to controls from other equipment
• All connections can be congured as input or output
• Additional voltage control connections allow for control functions that are variable rather than
simple on/off
FEATURES
• 16 total logic connections can be used as inputs or outputs
• Four of the 16 connections can be used as voltage control inputs
• Inputs can control actions within the software including: presets, mutes, ducking, room
combining, paging functions, and much more
• Outputs can trigger status relays, indicators or provide logic input to other controllable
equipment
• Serial port for the output of command strings
• Connects to Tesira SERVER or SERVER-IO over AVB
• Powered by PoE
• Plug-in barrier strip connections
• Front panel LEDs for device status indications
• Half-rack chassis
• RoHS compliant and AES grounded
• Covered by Biamp Systems’ 5-year warranty

TESIRA EX-LOGIC REAR PANEL
1 – Grounding pin. This pin is for grounding the chassis of the expander
2 – Ethernet data connection. Uses a standard RJ-45 connector with CAT-5, CAT-5e, CAT-6 or
CAT-7 cabling. The maximum distance between any unit and an Ethernet switch is 328 feet (100
meters). The expander must receive PoE (IEEE 802.3af) power on this connector in order for
proper operation.
This connection is for sending and receiving control data with the Tesira server. The expander will
not operate if it is not on a network that includes a Server-Class Tesira device.
3 – Serial Control port. The serial port can be utilized to send a control string to another device.
4 – Connections 1-12. These GPIO connections can be used as either inputs or outputs. They can
be assigned to actions within the software using Logic Input and Logic Output blocks.
When congured as logic output, each of the 16 GPIO pins can be congured to enable a current
source capable of driving an LED. The current source is enabled depending on the state of the logic
output block.
5 – Connections 13–16. These connections can function in the same way as connections 1-12
for digital GPIO. But they can also be assigned as variable voltage input controls to allow analog
control within the Tesira system by connection to a potentiometer.
GPIO pins 13–16 can be congured individually by the Control Voltage block in the software. If
any one of these is congured for voltage control, then the logic expander will turn on the 5V
potentiometer power.
Voltage Control Calibration
The four analog GPIO pins support voltage control calibration because a potentiometer may not be
able to achieve the full range of voltage expected by the internal analog/digital convertors. When
calibrated, the logic expander records both the minimum and maximum voltage levels caused by
the potentiometer to achieve the full range of voltage. A 10K Linear Potentiometer or similar value
is suggested.

FCC COMPLIANCE
FCC NOTICE - CLASS A DIGITAL DEVICE
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
