INTERFACE SPECIFICATIONS • • SATO MB2i Service Manual Interface Specifications AD-HOC Connectivity PN 9001145B Page 3-1
Unit 3: Interface Secifications INTERFACE SPECIFICATIONS This chapter presents the printer interface types and their specifications. These specifications include detailed information to assist in the selection of the most appropriate method for the printer to interface with the host. The acceptable interface methods are: • 802.
Unit 3: Interface Specifications 802.11B WIRELESS INTERFACE 802.11 refers to a family of specifications developed by the IEEE for wireless LAN technology to communicate between a wireless client and a base station or between two wireless clients. This interface only uses DSSS which allows wireless functionality comparable to Ethernet. The wireless print server provides easy printer interface with 802.11b Wi-Fi compliant networks free of wired connections.
Unit 3: Interface Secifications RS232C SERIAL INTERFACE This interface is an industry standard for serially transmitting data using a wired cable. Separate transmit and receive lines enable data to flow in both directions simultaneously. Data transmitted using this protocol is defined in its parameters; baud/bps (speed), data bits, stop bit, parity, and hand-shaking method. To change the parameter settings, refer to the Programming Reference document for this product.
Unit 3: Interface Specifications INFRARED RAYS (IRDA) Infrared communications is based on technology which is similar to entertainment remote control devices used in homes today. This technology offers a convient, interoperable, low power, and reliable way to connect computer and printer without the use of cables. The half-duplex, serial data interconnection capabilities supports walk up point-to-point use.
Unit 3: Interface Secifications The IrCOMM protocol runs on top of IrDA and supports the emulation of a peer device similar to what’s connecting it by a serial or parallel cable for applications that access those ports through the operating system. Since various communication and printing applications utilize cables differently, cable emulation must account for those differences.
Unit 3: Interface Specifications BLUETOOTH Bluetooth is a short-range, wireless technology operating in the unlicensed 2.4GHz band and offers greater flexibility than IrDA. Its signal is broadcast omni-directional and transmits/receives up to a distance 30 feet (10 meters). Typically, the data is directed through a Bluetooth assigned COM port on a PDA which handles all COM port protocols. Refer to the manufacturer’s documentation PocketPC device setup. Default Parameters: DSW1,3,4 OFF / DSW2 ON.
Unit 3: Interface Secifications ALL INTERFACE TYPES RECEIVE BUFFER The data stream is received from the host to the printer one job at a time. This allows the software program to maintain control of the job print queue so that it can move a high priority job in front of ones of lesser importance. The printer receives and prints one job at a time. If a print job exceeds the buffer size, transmission will be rejected by the printer.
Unit 3: Interface Specifications AD-HOC CONNECTIVITY To configure the printer for ad-hoc connectivity, an RS232 port and cable is initially required to use the Wireless Utility. The following two sections provides direction to the necessary tools, then procede to the next consecutive sections to begin setup. NOTE: An 8-pin DIN to 9-pin RS232 cable may purchased from SATO. MB200i WIRELESS LAN CONFIGURATION TOOL (v1.0.0) The software may be downloaded from: http://techsubweb.satoamerica.
