3. OPERATING RECOMMENDATIONS
* Since a DC/DC converter is used, the range of +5V
* Uses RS-232 serial interface with communication speeds from 4,800 to 38,400bps.
* Display windowing commands are available using PTC or Epson command sets.
* High quality blue-green(505nm) vacuum fluorescent display provides an attractive and readable medium. Other colors can
* Has the ability to design user-defined characters that are stored in a non-volatile EEPROM.
* Command emulation modes include: PTC, EPSON, ADM787, ADM788, AEDEX, UTC_S, UTC_E, DSP800, ICD-2002.
* This specification applies to VFD module (Model No.; 20LL04DA1) manufactured by SSVD (Shanghai Samsung
* Avoid applying excessive shock or vibration beyond the specification for the VFD module.
* Since VFDs are made of glass material, careful handling is required. i.e. Direct impact with hard material to the glass
* When mounting the VFD module to your system, leave a slight gap between the VFD glass and your front panel. The
* Avoid plugging or unplugging the interface connection with the power on, otherwise it may cause the severe damage to
* Exceeding any of maximum ratings may cause the permanent damage.
* Since the VFD modules contain high voltage source, careful handling is required during powered on.
* When the power is turned off, the capacitor does not discharge immediately. The high voltage applied to the VFD must
* The power supply must be capable of providing at least 5 times the rated current, because the inrush current maybe 5
* Avoid using the module where excessive noise interference is expected. Noise may affect the interface signal and causes
* Since all VFD modules contain C-MOS ICs, anti-static handling procedures are always required.
* Fixed display for prolonged periods of time leads to deterioration of the quality of display. Mobile display or changing
