iii ■ Technical Terms Used in This Manual Source Program and Object Program (User Program) Generally, a source program is translated into an object program by a compiler. This manual calls an object program a user program. BHT-BASIC This manual expresses BHT-BASIC3.
iv SAFETY PRECAUTIONS Be sure to observe all these safety precautions. ■ Please READ through this manual carefully. It will enable you to use the BHT and CU correctly.
v W ARNING Handling the battery cartridge • Never disassemble or heat the battery cartridge, nor put it into fire or water; doing so could cause battery-rupture or leakage of battery fluid, resulting in a fire or bodily injury.
vi W ARNING • Do not look into the light source through the reading window or point the light source towards the eyes. The light emitted through the reading window is harmful to the eyes. • Do not poke at the eyes with the stylus that comes with the BHT.
vii CAUTION Basic handling tips • Never put the BHT in places where there are excessively high temperatures, such as inside closed-up automobiles, or in places exposed to direct sunlight. Doing so could affect the housing or parts, resulting in a fire.
viii CAUTION • If you drop the BHT so as to damage its hous- ing, immediately turn off the power, pull out the rechargeable battery cartridge or dry bat- tery cartridge, and contact your nearest dealer.
ix CAUTION • Never cover or wrap up the CU or AC adapter in a cloth or blanket. Doing so could cause the unit to heat up inside, deforming its hous- ing, resulting in a fire. Always use the CU and AC adapter in a well-ventilated area. • Do not place the CU anyplace where it may be subjected to oily smoke or steam, e.
x ■ Proper Care of the BHT and CU Clean the housings, battery cartridge terminals, and CU-7001 charge terminals with a dry, soft cloth. Before cleaning, be sure to turn the BHT power off and unplug the AC adapter of the CU. • Never use benzene, alcohol, or other or- ganic solvents.
xi Labeling FCC Regulations This Device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

1 Chapter 1. Quick Guide Chapter 1 Quick Guide This chapter describes the basic operating method of the BHT and the related notes. 1.1 Reading 2D Codes and Bar Codes ............................................................................ 2 BHT -100Q .
2 • The markers show the left-to-right scanning range. When the scanning distance is 8.5 to 9.5 cm (3.3 to 3.7 inches), they indicate almost the center of the up-down scanner’s view. If the distance is out of the range, those markers will deviate from the center.
3 Chapter 1. Quick Guide • Before reading 2D codes or bar codes, clean those labels if stained. • Avoid using the BHT in direct sunlight. The BHT might fail to read correctly.
4 • If the BHT fails to read due to specular effects or other factors, change the scanning angle of the reading win- dow or the distance from codes as shown at right, and try it again. (Specular effects occur when the reflec- tion of the light from the bar code becomes exces- sively strong.
5 Chapter 1. Quick Guide • Before reading bar codes, clean those labels if stained. • Avoid using the BHT in direct sunlight. The BHT might fail to read correctly. • To read bar codes on curved surfaces, apply the BHT to the target bar code so that the code comes to the center of the scanning range indicated by the laser beam.
6 1.2 Setting and Using the Hand Strap and Stylus ■ Setting the hand strap ■ Using the hand strap Put your hand through the hand strap and hold the BHT as shown below.
7 Chapter 1. Quick Guide ■ Setting the stylus ■ Using the stylus The BHT has a touch screen LCD that enables you to use touch keys and draw images on the touch screen with the stylus if you have defined those touch keys and graphics pad box in user programs, respectively.
8 1.3 Setting the Backlight Pressing the right-hand trigger switch ( M4 key) while holding down the SF (Shift) key activates or deactivates the backlight function.
9 Chapter 1. Quick Guide 1.4 Using the Keypad ■ Entering Numerical Data To enter numerical data, e.g., the quantity of goods, use the ten numerical keys and the ENT key. For example, to enter the number "120," press the 1 , 2 and 0 keys and then press the ENT key.
10 ■ Using infrared link Using infrared rays, the BHT may transfer data directly to the host computer equipped with an IrDA interface port and other IrDA-compliant devices. • Make sure that there is no obstruction in the light path between the BHT and any target stations.

114 ■ Transmission Code and Bit Order All characters should be coded to 7- or 8-bit code for data transmission. The standard data exchange code of the BHT is JIS 7- or 8-bit code.
115 Chapter 3. Communications Operations of the BHT-100Q/100B 3.3.2 Communications Parameters In System Mode and user programs written in BHT-BASIC, you may set the communi- cations parameters listed below.
116 3.4 Communications Protocols The BHT supports both the BHT-protocol and the BHT-Ir protocol for file transmission. 3.4.1 BHT -pr otocol [ 1 ] Overview The BHT-protocol is the communications procedure used to transmit files between the BHT and a host (or between the BHTs).
117 Chapter 3. Communications Operations of the BHT-100Q/100B [ 2 ] Control Characters The control characters are classified into two groups: transmission control characters and text control characters.
118 (2) T ext control characters The text control characters are used to format transmission texts. In the BHT-protocol, they include the following headers and a terminator. Symbol Value Meaning Function SOH 01h Start Of Heading Indicates the start of heading text (Phase 2).

165 Appendices ■ Abnormal termination of phase 1 (Abort of phase 1) If the sending station receives no ACK from the receiving station after sending an ENQ 10 times in succession, it sends an EOT to the receiving station after three seconds from the 10th ENQ to terminate the message transmission abnormally.
166 Phase 2: Data Transmission ■ Normal phase 2 The sending station first sends a transmission block containing the heading text. Each time the sending station receives an ACK from the receiving station, it sends a transmission block containing the data texts as shown below.

176 Phase 2: Data Transmission ■ Normal phase 2 The sending station first sends a transmission block containing the heading text. Each time the sending station receives a sequence of DLE ACK and IDs from the receiving station, it sends a transmission block containing the data texts as shown below.
177 Appendices ■ Phase 2 with suspension of data reception for erasure of the flash memory If the receiving BHT requires the flash memory to be erased for receiving downloaded files, it sends a sequence of WACK and IDs to the sending station to suspend the data transmission.
178 ■ Phase 2 with a sequence of DLE NAK and IDs If the sending station receives a sequence of DLE NAK and IDs from the receiving station in response to a transmission block containing text data m, it sends that transmission block again immediately as shown below.
179 Appendices ■ Phase 2 with a sequence of DLE EOT and IDs If the sending station receives a sequence of DLE EOT and IDs anytime during phase 2, it shifts to phase 3 to terminate the message transmission abnormally. Even if phase 3 terminates normally, the transmission results in an abnormal end.
180 ■ Abnormal termination of phase 2 (Abort of phase 2) If the sending station receives no sequence of DLE ACK and IDs from the receiving station after sending a sequence of DLE ENQ and IDs 59 times in succession, it sends a sequence of DLE EOT and IDs to the receiving station after 0.
181 Appendices ■ Phase 3 with iterated transmission of DLE EOT and IDs due to no re- sponse or invalid response If the sending station receives no response or any invalid response from the receiving station in response to the sent sequence of DLE EOT and IDs, it iterates sending of the sequence at 0.
182 ■ Phase 3 with timeout at the receiving station If the receiving station receives no subsequent text or normal sequence of DLE EOT and IDs within 30 seconds after sending a sequence of DLE ACK and IDs, it sends a sequence of DLE EOT and IDs and aborts the transmission abnormally.
183 Appendices [ 3 ] CRC To check whether data has been transmitted accurately, the BHT-Ir protocol supports CRC (Cyclic Redundancy Check) which employs the CRC-16 generating system. In CRC, a CRC character is suffixed to a sequence of DLE ETX of every transmission block.
