2 ! Important Safety Notice Please read this note carefully before using the product. Warning The module should be disconnected from the power supply before handling. The power supply should be switched off before connecting or disconnecting the power or interface cables. The module contains electronic components that generate high voltages (approx.3v) which may cause an electrical shock when touched. Do not touch the electronic components of the module with any metal objects. The VD used on the module is made of glass and should be handled with care. When handling the VD, it is recommended that cotton gloves be used. The module is equipped with a circuit protection fuse. Under no circumstances should the module be modified or repaired. Any unauthorized modifications or repairs will invalidate the product warranty. The module should be abolished as the factory waste. AN-E-322 [Important Safety Notice]

And each one can be displayed independently and ON/O controlled as well. Also each screen can be composed (OR,EX-OR and AND). The followings are all commands of this module. Command (C/D = "") Setting Data (C/D = "L") unction Screen & 2 are Displayed off Screen is Displayed on 2 Screen 2 is Displayed on 3 Screen & 2 are Displayed on 4 Write/Read address is automatically incremented 5 Write/Read address is holed 6 Unused Screen 2 select D D Display data write-in 9 D D Display data read-out A D D Setting lower address for Screen started B D D4 Setting upper address for Screen started C D D Setting lower address for Screen 2 started D D D4 Setting upper address for Screen 2 started E D D Setting lower address of Write/Read D D4 Setting upper address of Write/Read OR display of Screen & 2 EX-OR display of Screen & 2 2 AND display of Screen & 2 Note) " "in the above table is shown that the setting data is not needed.

8 3-4. UNCTION O COMMANDS Screen Display on/off control ( 3) The latest command becomes effective. At power on, screen and 2 are set to display off mode. Therefore, the display on mode command should be written in, after display pattern data. (If it is executed in order, random pattern may be displayed.) Screen OR/EX-OR/AND Display Select ( 2) The latest command becomes effective. When these commands are executed, in advance, a "" command is needed to be executed (screen 2 is enabled to display.) Setting of Write/Read Address Mode (4,5) These commands select either the write/read address is incremented automatically or is held after data write/read. Screen 2 select () This command is enabled screen 2 to displayed. Data Write/Read (,9) After executing the Write/Read address setting command, this command shall be executes. At executing the data Read, the first byte is invalid. Dummy read is necessary. The correct data can be read from the second byte. Setting of Display Start Address (A D) The display start address is just pointed to the left and the top line of the display area. Screen and 2 can be independently set the display start address each other. This address is divided to the two portion with upper (five bits) and lower (eight bits) address, and lower address shall be set first, then set the upper address. The smooth scroll of displaying can be achieved by synchronizing with the Change of display address by the INT signal at every frame. Setting of Write/Read Address (E,) This command is set the write/read address of displaying data, This address is divided the two portion with upper (five bits) and lower (eight bits) address, and lower address shall be set first, then set the upper address. And only the upper address is available to be changed independently. When the lower address is changed, it is required to change the both address. AN-E-322 [5/2]

15 . WARRANTY This display module is guaranteed for year after the shipment from UTABA.. CAUTIONS OR DETERMINING AND EXPORTING REGULATED GOODS OR SERVICES This product does not correspond to the goods or services regulated by Japan s oreign Exchange and oreign Trade Law. If this product is combined with other products in order to make equipment, whether this product is regulated or not is judged by such newly made equipment. We ask you to determine by yourself whether the equipment corresponds to the regulated goods when this product is incorporated in the equipment. We also ask you to confirm that this product will not be incorporated in any weapon or used for manufacturing any weapon. If you export or re-export this product, we recommend you to adopt measures for appropriate export procedures, if any. 9. CAUTIONS OR OPERATION 9-. Applying lower voltage than the specified may cause non activation for selected pixels. Conversely, higher voltage may cause non-selected pixel to be activated. If such a phenomenon is observed, check the voltage level of the power supply The DC/DC converter generates approximately 3Vdc, avoid touching it with bare hands, or to other circuits Avoid using the module where excessive noise interface is expected. Noise affects the interface signal and causes improper operation. Keep the length of the interface cable less than 3cm. (When the longer cable is required, please confirm there is no noise affection.) 9-4. When power is turned off, the capacitor will not discharge immediately. Avoid touching IC and others. The shorting of the mounted components within 3 sec., after power off, may cause damage When fixed pattern is displayed for a long time, you may see uneven luminance. It is recommended to change the display patterns sometimes in order to keep best display quality DC/DC converter is equipped on the module, the surge current may be approximately 5 times the specified supply current at the power on. REMARKS : The specification is subject to change without prior notice. Your consultation with UTABA sales office is recommended for the use of this module. AN-E-322 [2/2]
