Specifications Manual
1. Abstract
This manual provides specifications for the C37 barcode scanner.
2. Overview
The C37 is a handheld CCD barcode scanner. A new scanning algorithm and 2500 pixels-CCD
linear image sensor provide smooth scanning performance.
The C37 can be configured to scan both positive and negative barcodes. Scanned data is
transferred via an RS-232C, USB, or Wedge interface. Auto-trigger settings are available.
The C37 complies with RoHS.

5. Electrical Specifications
5.1. Framework and Structure
This product consists of an optical section, a decode and a communication section. The
optical section includes a CCD for decoding and an illumination LED. The decode section
decodes scanned data and carry out signal processing. The communication interface
section converts 3.3V power supply and outputs decoded data and signals to the buzzer,
LEDs and trigger key
The C37 with RS-232C interface requires the supplied AC adaptor.
The C37 with Wedge or USB interface uses bus power. It does not require an AC
adaptor.

c) ACK/NAK
After data has been transmitted, the scanner expects to receive one of the
following responses from the host:
ACK response—Action: The scanner completes transmission with the goodread buzzer and returns to the initial state.
NAK response—Action: The scanner sends the data again and waits for the
response from the host.
DC1 response—Action: The scanner returns to waiting for the trigger, if it has
a trigger (the initial state).
None response—Action: The scanner sounds the error buzzer and returns to
the initial state.
