¦ Problem The memory has already contained 80 files, so the BHT system message file cannot be set up. ¦ Solution Press the C key to return to the SYSTEM MENU, then delete unnecessary files in the memory. (Refer to Subsection 2.5.3, [ 9 ]. ¦ Problem Uploading has failed. ¦ Solution To retry uploading, press the 1 key. To return to the SYSTEM MENU, press the 2 key. Check the interface port, communications parameters, and communications protocol type in the SET SYSTEM menu or perform the communications test in the TEST menu. (Refer to Subsection 2.5.3, [4.5] and [5.5].) It is also necessary to check the communications parameters setup of the host computer. 122 Chapter 3 Chapter 3 Communications Operations of the BHT This chapter describes the communications operations of the BHT-7500/7500S/7500W— the spread-spectrum communication (for BHT-7500S/7500W only), IR communication, RS-232C interface specifications, the basic communications specifications, and the communications protocols—for data transfer with the host computer or other devices. 3.1 Spread-Spectrum Communication (BHT-7500S/7500W only) ............................ 124 3.1.1 Notes for Wireless Operations ...................................................................... 124 3.1.2 RF-Related Parameters ................................................................................... 124 3.2 Infrared Communication ....................................................................................... 126 3.3 RS-232C Interface Specifications .......................................................................... 127 [ 1 ] Interface Connector and Pin Assignment ............................................. 127 [ 2 ] Interface Cable Connection .................................................................... 128 3.4 Basic Communications Specifications and Parameters ..................................... 129 3.4.1 Basic Communications Specifications .......................................................... 129 3.4.2 Communications Parameters ........................................................................ 131 3.5 Communications Protocols ................................................................................... 132 3.5.1 BHT-protocol ................................................................................................... 132 [ 1 ] Overview .................................................................................................. 132 [ 2 ] Control Characters .................................................................................. 133 [ 3 ] Basic Format of Transmission Messages .............................................. 135 [ 4 ] Text Format .............................................................................................. 136 3.5.2 BHT-Ir Protocol ................................................................................................ 138 [ 1 ] Overview .................................................................................................. 138 [ 2 ] Control Characters .................................................................................. 139 [ 3 ] Basic Format of Transmission Messages .............................................. 141 [ 4 ] Text Format .............................................................................................. 142 123 3.1 Spread-Spectrum Communication (BHT-7500S/7500W only) 3.1.1 Notes for Wireless Operations • If there are too many communications errors, first make sure that the BHT points directly at an access point because the 2.4-GHz band requires a more or less straight line path. Note also that the low-power radio waves have trouble passing through human bodies and other obstacles along that path. • The radio link will not operate properly in the vicinity of microwave ovens, industrial heaters, high-frequency medical equipment, and other sources of radio waves in the 2.4-GHz band. • Electromagnetic noise from personal computers, refrigerators, and other home appliances can also interfere with link operation. • Environmental factors that can also interfere with link operation include large metallic objects, metallic dust, or metallic walls in the vicinity of the path and vibration at either end. To System Designers: • Before developing the application, make sure that the intended environment is free of the interference factors above and thus actually capable of supporting link operation. •Assume that there will be communications failures requiring robust retry capabilities in the software. 3.1.2 RF-Related Parameters Programs written in BHT-BASIC control wireless communication with commands between the BHT terminals and access points which are connected each other by a wireless LAN. BHT-7500S For the setting procedure of RF-related parameters, refer to Subsection 2.5.3, "[ 8 ] RF Menu BHT-7500S." ¦ Domains It is necessary to group a wireless LAN into domains and assign them with unique domain names. A domain name s...
