(RSS) (Limited/ Stacked/ Expanded versions). Aimer The RT209 has a view finder that produces a bar-shaped aiming pattern to help the user to easily position the target barcode within the engine’s field of view to increase scan efficiency. The aiming pattern can be turned On or Off. -
Page 5: Chapter 2 Installation
Chapter 2 Installation General Requirements ESD protection has been taken into account when designing the RT209 and the engine is shipped in ESD safe packaging. Always exercise care when handling the engine outside its package. Be sure grounding wrist straps and properly grounded work areas are used. -
Page 6: Installation Orientation
Installation Orientation The following figure illustrates a front view of the RT209 after installation. Optics Window Placement The window should be positioned properly to let the illumination and aiming beams pass through as much as possible and no reflections back into the engine (reflections can degrade the reading performance). -

90% and haze less than 1%. Whether to use an anti-reflection coating or not depends on the material and application needs. Scratch Resistance and Coating Scratch on the window can greatly reduce the performance of the RT209. It is suggested to use abrasion resistant window material or coating. Window Size The window must not block the field of view and should be sized to accommodate the aiming and illumination envelopes shown below. -
Page 8: Ambient Light
Eye Safety The RT209 has no lasers. It uses LEDs that create the aiming and illumination beams. These LEDs are bright, but testing has been done to demonstrate that the engine is safe for its intended application under normal usage conditions. -

Chapter 3 Electrical Specifications Power Supply Do not power up the RT209 until it is properly connected. Be sure the power is cut off before connecting a flexible cable to or disconnecting a flexible cable from the host interface connector. Hot-plugging could damage the engine. -

Chapter 4 Interfaces The following table lists the pin functions of the 12-pin host interface connector on the RT209. Refer to the “Cable Connection” section in this chapter for the location of Pin 1. PIN# Signal Name Function Power supply. -
Page 13: Host Interface Connector
Host Interface Connector The RT209’s host interface connector is a 12-pin ZIF socket (bottom contact) which can be used to connect a host device (e.g., software development board EVK) with an FFC cable. The following figures show the location and dimensions of the socket. (unit: mm) -
Page 14: Dimensions Of The Host Interface Connector
FFC Cable A 12-pin FFC cable can be used to connect the RT209 to a host device. The cable design must be consistent with the following specifications shown below. Use reinforcement material for the connectors on the cable and reduce cable impedance for reliable connection and stable performance. -
Page 15: Cable Connection
Be sure the power is cut off before connecting a flexible cable to the host interface connector on the RT209. Hot plugging could damage the engine or the host device. Connect the RT209 to a host device with a 12-pin flexible cable as shown in the following figure. Communication Interfaces The RT209 can communicate with the host device through either TTL-232 serial port or USB port using one of the following communication modes. -
Page 16: Control Interfaces
Driving the TRIG pin (PIN 12) on the host interface connector low for a specified time period causes the RT209 to start a scan and decode session. The time period varies from one scan mode to another. Anti-shake mechanism is used in level trigger mode. For this mode, a trigger begins when the signal from the TRIG pin remains low for at least 10ms. -
Page 17: Beeper
Beeper The RT209 provides a pin (BUZ, PIN 9) on the host interface connector that provides a PWM output to an external driver circuit for generating audible feedback to the user to indicate statuses like power up, good read or operation error. The PWM output is not strong enough to drive a beeper, so a beeper driver circuit is needed. -
Page 18: Good Read Led
Good Read LED The RT209 provides a pin (LED, PIN 10) on the host interface connector that can be used by an external driver circuit to drive an LED to indicate a good read status. When a good read occurs, the signal from the LED pin turns from a low level into alternation of high and low levels and a while later back to a low level. -

The EVK is provided to help users to test and evaluate the RT209, which contains beeper & beeper driver circuit, LED & LED driver circuit, trigger & reset buttons, TTL-232 to RS-232 converter & TTL-232 to USB converter, RS-232 &...
