1. Overview

1.1 Product Overview

The DT-900 has been designed to be a superior model over the DT-700, which is the basic model ofa data collection terminal. While maintaining compatibility with conventional machines, the DT-900has greater screen resolution (128 x 64 dots), improved data processing capabilities, and multiplepower supply support. Also, the model (DT-900M50E) with a downward pointing nose that has beenadded to the line up, has improved the ease-of-operation in scanning barcodes on horizontal surfaces.These various models allow model selection according to user needs.

10. DT-960IO-E (Basic I/O Box)

10.1 Overview

The DT-960IO-E is a basic I/O box for CASIO DT-900 Data Collection Terminal.This Basic I/O Box facilitates non-contact data transfer between a personal computer and DT-900, and if multiple I/O Boxes are chain-connected, it facilitates connecting multiple DT-900 units to asingle personal computer host. It has an RS-232C interface for connection to personal computer andan optical I/F using CASIO original protocol for connection to a DT-900. Also, it can supply powerto a mounted DT-900.

10.1.1 Features

� Casio-original protocol optical communication with DT-900Employs an optical communication with DT-900.

� Chain links multiple Basic I/O BoxesThe RS-485 driver/receiver is used to connect a maximum of sixteen DT-960IO-Es with a totalline length of 1 Km.

� Power supply capability for DT-900The built-in circuit has a capability of supplying power to the DT-900 preventing the batterypower from being used by the DT-900 during communication.

� Wall-mounting and/or DT-900 tilting capabilitiesThe wall-mounting unit, which was used in the DT-760IO-E, allows the DT-960IO-E to behung on a wall or placed on a desk and tilted as necessary.

10.8.3 Notes About Chain Connection

Cable layoutTake the followings into consideration when routing the cables from each I/O Box:� Compression, extension, bending due to heavy load� Attachment to a movable part� Routing over a sharp edge� Routing near a strong electric field

Note:Improper routing of a cable may cause a cable fault or a short circuit, damaging propercommunication.

Do not route cables near precision equipment (measuring equipment, etc.), a radio or televisionreceiver, or wireless equipment. If cables are routed near such a piece of equipment, it may besubject to electrical interference.

Precautions to be observed when manufacturing cables� If the CASIO cables cannot be used, and custom-made cables are required instead, use the

manufacturer-specified cramping tool to cramp the modular connector and cable.Note:Defective cramping may damage communication.

� Cables for Basic I/O Box are designed for cross-type connection. Note that the number ofcore wires and connection method are different from those for Satellite I/O Box.

11. DT-964IO-E (Satellite I/O Box)

11.1 Overview

The DT-964IO-E (Satellite I/O Box) is an I/O box specifically for DT-900 data collection terminal.This Satellite I/O Box facilitates non-contact data transfer between a PC and a DT-900, and, ifmultiple I/O Boxes are chain-connected, it facilitates connecting multiple DT-900 units to a singleHost PC. It has an RS-232C interface for connection to a PC and an IrDA interface for connection toa DT-900. Also, it can supply power to a mounted DT-900.

11.1.1 Features

� IrDA Ver. 1.2 optical communication with DT-900Employs IrDA Ver. 1.2 for optical communication with DT-900.

� Chain links multiple Satellite I/O BoxesThe RS-422 driver/receiver is used to connect a maximum of eight units of DT-964IO-E with atotal cable length of 1 Km.

� Power supply capability for DT-900The circuit has a capability of supplying power to the DT-900, preventing the rechargingelectric energy from being used by the DT-900.

� Battery recharging capabilityThis I/O Box can recharge the battery being installed in DT-900 or can recharge a battery alone.Five hours is required to fully recharge the battery in the charging compartment.

� Wall-mounting and/or DT-900 tilting capabilitiesThe wall-mounting unit, which was used in the DT-964IO-E, allows the DT-964IO-E to behung on a wall or placed on a desk and tilted as necessary.

11.8.3 Precautions

Cable LayoutTake the following into consideration when routing the cables leading from each I/O Box:� Compression, extension, bending due to heavy load� Attachment to a movable part� Routing over a sharp edge� Routing near a strong electric field

Note:Improper routing of a cable may cause a cable fault or a short circuit, damaging propercommunication.

Do not route cables near precision equipment (measuring equipment, etc.), a radio or televisionreceiver, or wireless equipment. If cables are routed near such a piece of equipment, it may besubject to electrical interference.

Precautions to be observed when manufacturing cables� If CASIO cables cannot be used, and custom-made cables are required, use the manufacturer-

specified cramping tool to cramp the modular connector and cable.Note:Defective cramping may damage communication.

12. DT-969CHG-E (I/O Box Type Recharger)

12.1 Overview

The DT-969CHG-E (I/O Box-type/contact-type recharge unit) is a charging box for DT-900 datacollection terminal. It has the charging and power supply functions for DT-900, as well as there-charging function for a spare battery pack of DT-900.

12.1.1 Features

� Recharging and power supply function for DT-900It has incorporated a charging circuit for the main battery of the DT-900.Five hours is required to fully charge the battery. The circuit has a capability of supplyingpower to the DT-900, preventing the recharging electric energy from being used by the DT-900.

� Recharging function for spare battery packIt has the recharging function for a spare battery pack, DT-923LI, without installing it in theDT-900.

� Wall-mounting and/or DT-900 tilting capabilitiesThe wall-mounting unit, which was adopted in the DT-760IO-E, allows the DT-969CHG-E tobe hung on a wall or placed on a desk and tilted as necessary.
