Cutter driver (U2: R-200/R-200K) (JP29: R-400/R-400K/R-600/R-400plus/R-400Kplus)
In order to prevent the cutter from stuck, relay function cutter baby board will be handle the
cutter stop position.
RS232 driver/Receiver (U4)
To convert the serial port signal to/from micro-controller to RS232 voltage level, a RS232
driver/receiver with integral charge pump circuit is used.
CENTRONICS interface (U11, U13, U15)
Through these interface, all the data come from the host controller are latched them read by the
Micro-controller, EPROM, and DRAM...etc.
AC/DC converter (D1, C2, C3, C4, C5) (R-200/R-200K only)
To convert the AC 19V to DC 24V for motor drivers, TPH, and option deice cutter usage.
DC/DC regulator (R-200/R-200K only)
To regulator the 24V input power to 5V, to be used as the power supply for micro-controller,
EPROM, DRAM...etc.
DC/DC converter (U20, L1, D2)
To convert the 24V input power to 5V, to be used as the power supply for micro-controller,
EPROM, DRAM...etc.
Relay (RY2)
To prevent the TPH from being damaged by the unstable power condition when the printer is
switched on, RY2 disconnected the power supply (24V) to the TPH. RY2 has to be activated
before printing.
Extension slot (JP11)
This slot designate for the connection of all the optional extension modules.
USB (U2) (R-400plus/R-400Kplus only)
