Ithaca Series 70 Impact Printer
Series 70 Manual Configuration Dip Switches
Main Board Switch Settings
CHECK AND SET SWITCHES
The factory switch settings apply to most customer applications and normally do not need to be reset; however, the switch settings should be checked and set at this time, if necessary.
CONTROL BOARD
All Series 70 printers contain one large circuit board called the control board. Located on that board is one DIP switch pack containing 8 switches (called DIP SW on the circuit board).

SWITCHES 1 & 2
When this unit is shipped from the factory, the switches are set so that the unit prints US ASCII characters and the numeric 0 without a slash through it. The following table shows the available languages and switch settings.

SWITCH 3
Switch 3 controls the automatic line feed. It is set in the OFF position because most configurations of personal computers automatically send a line feed to the printer after the carriage return at the end of each line. If your configuration doesn't send a line feed at the end of each line, switch 3 can be set to the ON position to provide the line feed automatically. If your PC configuration does provide an automatic line feed, switch 3 can be used to provide automatic double spacing.
SWITCH 4
Switch 4 is used to select the take-up function of receipt/journal and receipt/journal/validation printers. With switch 4 ON, the journal take-up is disabled and with switch 4 Off, the take-up is enabled. The factory setting is OFF.
SWITCH 5
Switch 5 is used by the factory and should remain in the factory setting (OFF).
SWITCH 6
Switch 6 disables the 10 CPI print mode. With switch 6 in the ON position the printer will ignore the 10 CPI command (DC2) and will remain at the default setting of 17.1 CPI. Setting switch 6 to the OFF position enables the 10 CPI command. The factory setting is OFF.
SWITCH 7
Switch 7 selects the character set. This switch is factory set in the OFF position and establishes Character Set 1 as the default character set. In the ON position, Character set II, the IBM Graphics printer compatible character set is established as the default character set.

SW1:
SWITCHES 1 & 2 (SW1)
These switches work together to set the parity of the printer to match the parity of the computer system. The factory switch setting is for NO parity.

Note: 7-bit no parity is not a true 7-bit mode, it is 7-bit but does not care about parity. The parity bit must be present or the host must be configured for 7 bits with 2 stop bits.
SWITCH 3 (SW1)
This switch is set ON at the factory to select 8-bit data. Set this switch OFF for 7-bit data.
SWITCH 4 (SW1)
This switch is set ON at the factory for Printer Ready/Busy protocol. Set this switch OFF in the computer uses XON/XOFF protocol.
SWITCHES 5 & 6 (SW1)
These switches work together to run two serial cable tests. One test checks for proper switch settings, the other test checks the data cable to see if it is communicating properly. The factory setting is the non-test mode, called the print mode.

If the READY/BUSY protocol is selected (switch 4), then the line on which the printer sends the busy signal and the signal polarity (low or high) may be selected by setting switches 7 & 8. The switches are set at the factory for a negative (low) busy signal on pin 20 (DTR).

SWITCH 4 (SW2)
If the printer has pin #6, DSR, connected to the computer, then set this switch to the ON position. If the computer does not use the DSR signal, then leave this switch in the OFF position.
SWITCH 5 (SW2)
This switch is factory set to ON so that the printer waits until the print buffer has room for only 32 more bytes before sending a busy signal to the computer. If some data is lost during transmission, set this switch OFF. Then the printer sends a busy signal when room for 256 more characters remain in the buffer.
SWITCH 6 (SW2)
This switch is set ON at the factory for a 200 ms busy time. This is the period of time it takes the printer to empty the print buffer and get ready to receive data. If the computer requires more time to process a response set this switch to the OFF position.
SWITCHES 7 AND 8 (SW2)
These switches work together to control the Multidrop Communications Mode. On printers not equipped with the Multidrop Option, leave the switches in the factory setting, 7 on and 8 off.
