Scantech-ID Discovery SG-20 93 Type A char[2] field. These characters describe the type of record (S0, S1, S2, S3, S5, S7, S8, or S9). Only records S0, S1, S2, S7, S8 and S9 are supported by the Discovery Count A char[2] field. These characters when paired and interpreted as a hexadecimal value, display the count of remaining character pairs in the record. Address A char[4,6, or 8] field.
94 Appendices S7 Record The type of record field is 'S7'. The address field contains the starting execution address and is interpreted as 4-byte address. There is no data field. S8 Record The type of record field is 'S8'. The address field contains the starting execution address and is interpreted as 3-byte address. There is no data field. S9 Record The type of record field is 'S9'. The address field contains the starting execution address and is interpreted as 2-byte address. There is no data field.

This means that font sets can not be downloaded together with images and Icons.
96 Appendices eg : 0x1400 should be formed as ASCII characters '1' '4' '0' '0' (or in hex values : 0x31 0x34 0x30 0x30). After receiving the command, the Discovery checks if the user is permitted to clear the region. If anything is incorrect (that is, the start address is out of region (see also the memory map explanation), or the length is too high) the Discovery responds with a 'NACK' - character (0x15). If everything checks out correctly, the Discovery starts to clear the given region.
Scantech-ID Discovery SG-20 97 - S-Record too long. - Address of the S-Record out of range. - Write to Flash not successful. Some notes : It's up to the host to take the proper actions, when for example the Discovery doesn't respond in time (Timeout) or when a NACK has been transmitted. E.g. a number of retries could be performed until a certain limit. When the Discovery has received an S7, S8 or S9 record, it assumes the upload action is finished.

Scantech-ID Discovery SG-20 105 Is every Discovery delivered with a CD-ROM and User’s Manual? Yes, however with larger orders we apply a ratio: one set per so many units. Do you have brochures available in other languages? English & Spanish Brochures are currently available. Other translations are planned. Can you generate quickly an image (such as a bitmap) on the Discovery screen? Sure. You can display up to 36 pre-stored images, even sequential in very high speed to create animation effects.
106 Appendices Can I make and download my own full screen images? Yes, using MS-Paint or a similar program, you can generate your own bitmaps. Required format: 240 x 128 pixels, 2 bits colourdepth (B&W). Using I-Start or U-Start (or your own application), you can send it to the Discovery. Which I-Start/U-Start version do I have? For I-Start: Click on the Discovery picture in the opening screen. For U-Start click on the “Scantech–ID” name just above the Discovery screen.
Scantech-ID Discovery SG-20 107 additional charactersets in your Discovery, so you have complete freedom of style and type of characters. What is de difference between I-Start and U-Start? I-Start is a demonstration tool and info source for the Discovery basic model (RS232/422/485). It provides a general overview of its capabilities and examples of use. Helpful are the large Help-file system and some tools to change and load Icons, Screenbitmaps and character sets.
108 H-3 Appendices DRIVERS & OPERATING SYSTEMS For which Operating Systems (OS) is a Discovery RS-485 network driver available? WIN 95/98, WIN NT, WIN 2000, WIN XPSCO UNIX, LINUX and Solaris. What does this driver actually do? The general function of the Discovery RS-485 network driver is: Data routing, data formatting/packaging, error correction, terminal control (switch on/off terminals etc).
Scantech-ID Discovery SG-20 109 What is the difference between RS-232, RS-422 and RS-485, while talking about the SG-20? RS-232. The most simple, single unit configuration, full duplex, 4 wires + ground, maximum distance between the Back Office and the terminal: 15 meters. RS-422. Single unit configuration, full duplex: sending and receiving data simultaneously. (in practice: 4 data wires/ crossed) max. distance 1200 meters. RS-485.
110 Appendices flexible in rearranging your workfloor layout. If organised well, you could even access your Discovery’s ‘all over the world’. Which cable type should I use for the network? For instance: Unshielded Twisted Pair (UTP) CAT5 cable. See for further cable specifications Appendix A “Connector types and pin definitions”. Can I have a network with only one Discovery? Yes, but the immediate advantage is limited.
Scantech-ID Discovery SG-20 111 Why do I sometimes encounter connection problems? Check for the right jumper settings. Is the right type of cable used and the max. length not exceeded? Check the wiring of the cable, connect (as described in the manual) only the required lines, leave other pins open. RS-422 How many Discoveries can be connected under RS-422? In principle one, by applying additional COM ports on the Back Office computer system you can increase this quantity.
112 Appendices However, in order “to get started” with the Discovery, this is a logical route when migrating from SG-10 to SG-20. Can the SG-10 be swapped for a SG-20? Yes, always set the Discovery in SG-10 mode of course, by means of the buttons. Talking about network mode: Using the old SG-10/DOS driver, this swap can be done with the same network box. Under WIN NT a new network box (P/N A361501 or higher) is needed. Always set the SG-20 for the right terminal address in the network.
Scantech-ID Discovery SG-20 113 What is the default authorisation code? Holding the lower button for about 3 seconds, the terminal will ask for the authority code. Just press the 4 buttons from top to bottom in that order. This will open up the Terminal Configuration Menu. After that follow the indications and icons on the display. H-9 BACK-OFFICE Is logging of the RS-485 network activities possible? Yes, at the Unix driver there’s a help utility, which can log the network traffic (see read-me file).
114 Appendices Does the Discovery have an internal memory for an article database? No, we have chosen not to do this for the following the reason: It is crucial that the information given to the consumer on the Discovery display is correct. The best solution to achieve this high level of data integrity is to draw the information from ONE central source: The article data-base on the store’s Back Office computer.
Scantech-ID Discovery SG-20 115 with respect to e.g. type of interface, the network address or SG-10 compatibility mode. Are new software updates always automatically provided? Software upgrades are available upon request and will be supplied by E-mail to our Distributors.
116 Appendices I DISCOVERY PROJECT TASKS The integration of a Light Information Terminal like the Discovery into a store IT system is slightly more complex than linking a mouse to your PC. Therefore you find below ,to prevent any miscommunication, a general guideline describing “Who Does What While Launching A Discovery Project”. Scantech supplies: Discovery Hardware Configuration (excl. network cabling).
Scantech-ID Discovery SG-20 - Configuration of the Discovery terminals, through the regular store application plus the Discovery buttons or alternatively through the Scantech utilities (I/U-Start). - One minute swap time due to smart mounting, - No need to open the Discovery. - RS-485 Network Trouble shooting facility is available within I-Start (build up database).
118 J Appendices DISCOVERY IN SG-10 MODE The Discovery SG-20 has an operating mode, which makes it downwards compatible with its predecessor : the ScanGuide SG-10. This feature makes it rather easy for our Customer base of SG-10 users to migrate to the SG-20, without any alteration on their BackOffice software. At a later stage the Discovery BackOffice software can be upgraded, in order to take full advantage of all the functionality's of the Discovery.
