CS CHARACTER SPACING
This element determines the spacing between each character. If
this element is not used, then the default value for the
selected character generator (CGN) is selected.
TSP TEXT STARTING POSITION
This element determines where to start using data in the
selected text string (TSN). If this element is not used, then
it will be set to a value of one.
CLX CHARACTER CELL LENGTH X DIRECTION
This element will override the width of the characters in the
selected character generator (CGN). If this element is not
used, the default value for the selected character generator
(CGN) is selected. This element is used only for special cases.
CLY CHARACTER CELL LENGTH Y DIRECTION
This element will override the height of the characters in the
selected character generator (CGN). If this element is not
used, the default value for the selected character generator is
selected. This element is used only for special cases.
4.1 INTERFACE
Models 1100, 1400, 2000, M450, and M460 printers contain an RS-232C
compatible asynchronous communications port. This port is configured
as Data Communications Equipment (DCE). This allows a `One For One'
connection with a dumb terminal.
The following is the pin-out for the 25 pin RS-232C connector:
PIN 2 HOST DATA (To printer from terminal or host)
PIN 3 PRINTER DATA (From printer to terminal or host)
PIN 5 CLEAR TO SEND (From printer to terminal or host)
PIN 7 SIGNAL GROUND
The baud rate can be set by changing the jumper configuration. The
jumper can be found on the control board for the M450 and M460
printers. For the 1100, 1400, and 2000 they are on the serial I/O
board.
Other serial port functions can be set via the dip switch setting.
See the section on DIP SWITCHES.
4.2 DIP SWITCH SETTINGS
The dip switches on the memory expansion board inside the printer
allow the user to change communication parameters.
