6.4.3 About Configuring the Device for 802.11 Wireless

DynaPro Go ships from the manufacturer with TLS Enabled. This setting can be set to Disabled by the
customer, which may be useful for initial network setup and testing. MagTek strongly recommends
that TLS always be Enabled when it is deployed in the field.
Before DynaPro Go can communicate securely with the host using the 802.11 wireless connection, an
advanced operator must configure it with solution-specific, network-specific, and host-specific settings.
The steps in the following sections use the MagTek PCI PED Host App Simulator (also known as
PCIPED_HASim) to show examples of the device configuration sequence; this tool can be used for
initial pre-deployment testing and development, and as sample code showing how to communicate with
the device, but production rollout of the solution may call for custom software advanced operators would
use to configure the device and update firmware.
For further details about using the MagTek PCI PED Host App Simulator, see D998200168 IPAD,

DynaPro Go can be configured to communicate with the host using 802.11 wireless in one of two
Network Connection Modes:

In Device Initiated mode, the device does not listen for incoming connections, and instead expects to
initiate connections with the host on demand. In this mode, the device sends a notification to the host
requesting that the host initiate a handshake for a secured TLS connection, and opens a listening
socket for a limited period of time for the host to initiate the connection.

In Always Listening mode, the device keeps a TLS listening socket open that allows an authenticated
host to connect at any time.
In both cases, provided TLS is set to Enabled, DynaPro Go 802.11 wireless network connections use
TCP/IP protocol secured by TLSv1.2 using x509 certificates, and the device enforces a requirement of
mutual authentication between the device and the host. If the host attempts to initiate an unauthenticated
connection, the device refuses the connection and shows
section 7.2 How to Read Device Status). To clear this status, an operator should press key sequence
