See the table below for the secondary interfaces for the 3800g. 3800g Models Models Primary Interfaces Secondary Interfaces 3800G04E, 3800G14E TTL level RS-232, USB, Keyboard wedge TTL level RS-232 3800G05E, 3800G15E TTL level RS-232, IBM Retail, USB, Retail USB, Keyboard wedge TTL level RS-232 Enabling the Secondary Interface The secondary interface can be programmed at any time. You can temporarily disable the secondary interface, but still retain the secondary interface settings in the imager’s memory by scanning the Disable bar code below. To re-enable the secondary interface, scan the Enable bar code. Default =Disable. * Disable Enable Secondary RS-232 Connection All communication parameters between the imager and terminal must match for correct data transfer through the serial port using RS-232 protocol. 3800g User’s Guide 6 - 1 RS-232 programmable selections are used by both the primary and secondary interfaces. Changing an RS-232 parameter (e.g., baud rate or parity), while in primary or secondary mode will affect both interfaces. If you want to change the RS-232 settings, refer to the Connecting the Imager with RS-232 Serial Port section on page 1-6. RS-232 Interface Secondary Trigger Mode Manual Trigger: You must press the imager trigger to scan. When not scanning, idle power is maintained. Default = Manual Trigger. * Manual Trigger Automatic Trigger: The imager scans continuously at full power. Automatic Trigger Presentation Mode: The LEDs are off until a bar code is presented to the imager. Then the LEDs turn on automatically to read the code. Presentation Mode uses ambient light to detect the bar codes. Presentation Mode 6 - 2 3800g User’s Guide Hands Free Time-Out The Automatic Trigger and Presentation Modes are referred to as “hands free” modes. If the imager’s trigger is pulled when using a hands free mode, the imager changes to manual trigger mode. You can set the time the imager should remain in manual trigger mode by setting the Hands Free Time-Out. Once the time-out value is reached, (if there have been no further trigger pulls) the imager reverts to the original hands free mode. Note: If you change the time-out duration for the secondary interface, the duration of the primary interface will also be changed. Scan the Hands Free Time-Out bar code, then scan the time-out duration (from 0-300,000 milliseconds) from the inside back cover, and Save. Default = 5,000 ms.

Refer to Chapter 11 for settings and defaults. • All Symbologies • China Post Code • Codabar • Codablock F • Code 11 • Code 16K • Code 39 • Code 32 Pharmaceutical (PARAF) • Code 49 • Code 93 • Code 128 • UPC-A/EAN-13 with Extended Coupon Code • EAN/JAN 8 All Symbologies • Interleaved 2 of 5 • Korea Post Code • Matrix 2 of 5 • MSI • Plessey Code • PosiCode • RSS-14 • Straight 2 of 5 IATA (two-bar start/stop) • Straight 2 of 5 Industrial (three-bar start/stop) • Telepen • Trioptic Code • UPC A • UPC E If you want to decode all the symbologies allowable for your imager, scan the All Symbologies On code. If on the other hand, you want to decode only a particular symbology, scan All Symbologies Off followed by the On symbol for that particular symbology. All Symbologies On All Symbologies Off 3800g User’s Guide 7 - 1 Message Length You are able to set the valid reading length of some of the bar code symbologies. If the data length of the scanned bar code doesn’t match the valid reading length, the imager will issue an error beep. You may wish to set the same value for minimum and maximum length to force the imager to read fixed length bar code data. This helps reduce the chances of a misread. EXAMPLE: Decode only those bar codes with a count of 9-20 characters. Min. length = 09 Max. length = 20 EXAMPLE: Decode only those bar codes with a count of 15 characters. Min. length = 15 Max. length = 15 For a value other than the minimum and maximum message length defaults, scan the bar codes included in the explanation of the symbology, then scan the digit value of the message length and Save bar codes on the Programming Chart inside the back cover of this manual. The minimum and maximum lengths and the defaults are included with the respective symbologies. 7 - 2 3800g User’s Guide Codabar
