CBM-202PC User’s Manual 3.4 RESET CIRCUIT With RES terminal set to "Low", reset state is created. In order to assure resetting, it is necessary to hold "Low" for min. 20ms on supply of power and for min. 625ns while in operation. When external reset is not used, those parts inside the broken lines are not required.
CBM-202PC User’s Manual 3.5 OSCILLATION CIRCUIT A clock oscillator, being installed, generates a system clock and an internal clock. Two clock supplying methods are available including one to connect a ceramic oscillator and the other to input an external clock. When using a ceramic oscillator, you are recommended to use CSTCS16.00MX0C3 (with a condenser) manufactured by Murata Mfg. Co..
CBM-202PC User’s Manual 3.6 HEAD-UP DETECTION CIRCUIT Up/down state of the head is detected so that no power is supplied in head-up state, with the head-up sensor installed in the printer. With head UP, it becomes "OPEN". With head DOWN, it becomes "CLOSE". In head UP state, CPU's HEADUP (Pin 88) gets "HIGH", where printing is immediately stopped with error output if it is while in print operation. Printing is resumed when it becomes head DOWN.
CBM-202PC User’s Manual 3.7 HEAD DETECTION CIRCUIT VP is controlled so as to prevent the head from electrolytic etching. When turning ON the VP, set 11VC (Pin 4) of the gate array (CBM-202LA)to "HIGH". When turning it OFF, set the HVC to "LOW". It is also provided with a temperature detection circuit which serves to prevent print quality from being deteriorated or destroyed by temperature.
CBM-202PC User’s Manual 3.8 PAPER END DETECTION CIRCUIT Existence of printing paper is detected by the paper sensor which is installed in the paper not to supply power when paper runs our. Without printing paper, CPU PAPER (Pin 99) gets "HIGH". When this takes place while in printing operation, the operation stops at the end of the line, sending an error output. Printing is automatically resumed when paper is supplied.
CBM-202PC User’s Manual 3.9 MOTOR CONTROL CIRCUIT Except while in paper feed, the motor is held unexcited by CPU INH (Pin 97) so that heating of the motor is prevented. While INH is held in "HIGH", the motor is maintained unexcited. On supply of power, 4 dot lines of line feed is performed to meet the motor phase. Avoid continuous printing over 15 min.
CBM-202PC User’s Manual 3.10 AUTO CUTTER CONTROL CIRCUIT This CPU, by using the gate array (CBM-202LA), has auto cutter control function. When an auto cutter is not used, set DS1-1 to OFF. When DS1-1 is ON, alarm state is created where normal operation is interrupted.
CBM-202PC User’s Manual 3.11 PARALLEL INTERFACE CIRCUIT This circuit performs 8-bit parallel interface by mainly using the gate array ports. When the parallel interface is not used, pull up STB (Pin 52) of the gate array (CBM-202LA) through use of 10KΩ resistance. Also, either connect CPU's STB (Pin 87) to INTR (Pin 56) of the gate array or pull it up with 10K Ω resistance.

(negative logic) BUSY 55 Output Signal to indicate that data receiving is possible. (positive logic) Send data while it is in "LOW".
CBM-202PC User’s Manual 3.12 SERIAL INTERFACE CIRCUIT Serial interface applies asynchronous serial system. When not using serial interface, pull up, CPU's RXD (Pin 15) and DSR (Pin 100) with 10K Ω resistance.
CBM-202PC User’s Manual Signal Names and Functions SIGNAL NAME TXD PIN NO. 13 I/O FUNCTION Output Transmits status. When data receiving is not available while in XON/XOFF, XOFF (13H) is transmitted. When receiving is made possible, XON (11H) is transmitted. RXD 15 Input Receiving data signal. On occurrence of a framing error or parity error, the data are printed in "?".
CBM-202PC User’s Manual 3.13 SWITCH CIRCUIT This circuit is provided with switch input function for printer paper feeding. Also, a function for self printing is equipped through use of this switch. (Either supply power as pushing this switch or apply resetting in power supplied state as pushing this switch. Self printing starts automatically and, on completion of printing, normal standby state is recovered.
CBM-202PC User’s Manual 3.14 ERROR OUTPUT CIRCUIT Two kinds of error output are held for output of various errors. (Max. 10mA current can be taken for display with mainly LED, etc.. When this level is exceeded, however, CPU may be destroyed. Pay attention, therefore, to select an appropriate current control resistance, LED, etc..) CPU's LEDPE (Pin 4) is exclusively for output of paper error. When printing paper has got scarce, "LOW" is output automatically. When paper is supplied, it becomes "HIGH".
CBM-202PC User’s Manual 3.15 FUNCTION SELECTION CIRCUIT The gate array input ports have terminals for function selection. To connect a DIP switch, etc., do it as it is. When fixing with a jumper, etc., connect to GND only for those to be set to "LOW".

CBM-202PC User’s Manual 6. SPECIAL REMARKS FOR MOUNTING 6.1 CAUTIONS As relative humidity gets low, static electricity tends to be charged. Although surface mount type packages need to be stored in dry environments not to be affected by humidity, there is no worry for charging as the packages in storage are not subject to friction.
CBM-202PC User’s Manual 1) Thermal Gradient 1 On a sudden temperature increase, unevenness in temperature is produced among package parts of a surface mounting device, where difference in thermal expansion coefficients of materials can cause a warp in the package, resulting in damaged chips. Attention, therefore, should be paid to the upper limit for the increase speed. The lower limit is based on operation efficiency of the reflow device.
CBM-202PC User’s Manual 6.4 CLEANING METHOD As flux residue from soldering adversely affects reliability of parts and base PCB, it should be normally removed by cleaning. Ultrasonic cleaning, for example, is performed in the following conditions, for which cares should be taken to an applied frequency, electricity (especially, peak power), time and device resonance to prevent the device from breakage: Frequency Ultrasonic output Time Others ..... 28 to 29KHz (Device should not resonate.) .....
