7.4 About the Status LEDs
DynaFlex II Go provides four LEDs (see section 7.1 Component Details ), numbered LED1 through
LED4, which report the device’s current operating status.
•
The meaning of each LED depends on the device’s operating mode, see section
6.1 Operation
Overview
•
The operator initiates a transaction from the host, and the cardholder interacts with the device.
Transaction types may include new accounts, teller window applications, checking, savings,
mortgages, retail transactions, or any other type of transaction where there is interaction between the
cardholder and the operator.
•
For each transaction type, the host software directs the cardholder. The transaction flow on the device
may differ depending on what the host software specifies and what the cardholder does. Section
7.9
Card Reading provides examples of the cardholder experience for each type of payment. If the
device cannot read payment data, the host software may require the cardholder to repeat the action or
require the host to reject the transaction.
•
About Operating Modes. Most of the time, operators will check the device’s status using the LEDs
when it is in
Active Mode while the device is not performing a transaction.
•
LED blinking patterns have specific meanings as described in Table 7- . A blinking LED generally
means the device is actively doing something to change the state that the LED is indicating, and solid
indicates a persistent state that would require an operator or cardholder to take action to change. One
major exception is a device-wide functional failure state, such as a tamper state, where all LEDs flash
urgently to call the attention of an advanced operator to intervene.
In this manual, specific blinking patterns are described in more detail in the sections where they are
relevant. For example, information about how the LEDs show the device’s connection status is in section
4.3 Connecting DynaFlex II Go to a Host.

Device-wide failure
During major failures (such as tamper), LED1-LED4 report the nature of
the failure based on the most likely steps required to resolve it.

Solid LEDs generally require an operator or cardholder to take action to
change the state the LED is reporting.
Example: Host is connected. Cardholder or host would have to disconnect.
