[. . . ] CITIZEN User's Manual MINI DOT MATRIX PRINTER MODEL iDP-3530 Japan CBM Corporation Information Systems Div. iDP-3530 User's Manual IMPORTANT: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own expense will be required to take whatever measures may be necessary to correct the interference. CAUTION: Use shielded cable for this equipment. [. . . ] 4) Nothing shall be placed on the ventilation slots of the printer. 5) Always place your printer on a stable desk which is set horizontal. 6) No organic solvent (thinner, benzene or the like) shall be used in sweeping clean the surface of the main body case. 7) Make sure that the power of the printer is turned off whenever you do the following. (1) Taking out any foreign matter which were dropped into the printer. (2) Replacing the ribbon cassette. CITIZEN 13 iDP-3530 User's Manual 5. Serial Interface 5-1 Specifications 1) Synchronism : Asynchronous 2) Baud rate : 1200, 2400, 4800, 9600 BPS (Selected by user) 3) Composition of one word : Start bit : 1 bit Data bit : 7 or 8 bit (selected by user) Parity bit : Odd, even or parity (selected by user) Stop bit : 1 bit or more. 4) Signal polarity : RS-232C : Mark = Logic "1" (-3V to -12V) : Space = Logic "0" (+3V to +12V) 4) Receiving Control (DTR signal) : RS-232C : Mark = Data transfer not possible : Space = Data transfer possible 5-2 Connector Pin Assignment Pin No. 1 3 7 14 20 Signal Name FG RD SG FAULT DTR Direction Host / Printer Function Safety Ground Received Data Signal Ground Printer ALARM Signal Printer BUSY Signal RS-232C ¡ ¡ ¡ Notes: 1. The signal for RS-232C use are based on EIA RS-232C level. Please always maintain the "Mark state", when received data is not being transferred.

If the reading is SPACE, a start bit is recognized. 2) Data bits and Parity bit Data bit and Parity bit are checked out every bit form the half point of start bit. Signal level of these points (Mark = 1, Space = 0) are read as input data. The sequence of these bit is Bit 0, Bit 1 ~ Parity bit from Start bit. 3) Stop bit The stop bit consists of one or more bits at "mark" level. When "space" level is detected for a stop bit, a framing error occurs. 5-5 Error Detection The printer detects Parity, Framing and Overrun Error. When any error is detected, the data is printed out as (7FH). Framing Error; Framing error occurs when SPACE signal is checked out at STOP BIT and the printer print out (7FH). Parity Error; Parity check is carried out only when user designates it on the printer pre-setting. Input Control and Buffering; (over-run-error) The printer is designed to output DTR signals for each word. If the host computer neglects DTR signal and transmits the data, it may cause the "OVER-RUN ERROR". [. . . ] (3) Red Color Print Mode Designation DC2 (12) DATA CR (0D) All print data including DC2 are printed in red color and it's not possible to mix the black and red color characters on one line. This command will be automatically cancelled after the line feed. If DC2 commands are used 2 times on the same line by error, the printer will print out all characters in black color. (4) Paging Designation and Page Length Designation ESC (1B) c (43) n Input ESC + "C" (1B 43) at the top of the line and next input n, which are integers. [. . . ]
