IV7 Vehicle-Mount Reader Instructions
Sending Commands to the IV7
You send commands to the IV7 from a host PC using the Basic
Reader Interface (BRI) protocol. For more information on BRI
commands, see the
Basic Reader Interface Programmer’s Reference
Guide
(P/N 937-000-xxx).
To develop RFID applications you can use the Intermec RFID
Resource Kit, which is part of the Intermec Developer Library.
This resource kit includes C# and Java tools for application
development, including reader control and data manipulation.

About the GPIO Interfaces
The IV7 has four input and four output interfaces. You can
connect external controls to the GPIO interfaces, which can then
trigger IV7 operations.
All GPIO interfaces should be restricted to a maximum operating
input voltage of +5 VDC. To use higher input voltages, you need
to use an external voltage conditioning network, such as resistor
dividers or active regulators.
The GPIO interfaces can be accessed through the data port. For
pin assignments, see the next section.
Although all interfaces include transient protection, the
interfaces are not protected from continuous over voltage or
over current conditions. The IV7 will be damaged if a low
impedance source greater than +6.5 VDC is connected directly
to either the inputs or the outputs.
