3.4- COMMUNICATIONS INTERFACE
Serial Serial interface RS232/TTL (baud options 203400, 115200, 38400, 19200, 9600)
USB USB 2.0 480Mbit/s
3.5- INTERNAL BUFFER
The standard EPC1800 printer has a 32 Kbytes internal memory buffer, whose functionality is
dynamically shared by the receiving buffer.
The buffer is being filled at the same time that buffered data is being printed, for that reason high
transmission speed is required in order to ensure that data is available for printing at any time. Data
transfer of at least 115200 bauds or USB connection increase the printing performance substantially.
3.6- ELECTRICAL SPECIFICATIONS
Power supply: 5VDC ± 10% or 12-24VDC ± 10%
Consumption: The figures below show the relationship between average current and power
Fig. 2 - Current consumption vs input voltage (12-24VDC version)
consumption with the input voltage at a ambient temperature of 25ºC. Each
graph contains 6 parameters corresponding to when printer is in Stand-by, when
the printer is just feeding paper, and when the 25%, 50%, 75% and 100% the
dots are energized and paper is being feed at the same time. In both graphs,
parameters in blue have been multiplied by 10 for better representation.
*Paper Feed and Stand-by parameters are shown multiplied by 10.
