Communication Interface
The Configuration Menu gives the user the option of setting the printer to use an
RS-232C serial port. (See “Configuring the Printer” for instructions on how to
enter the Configuration Menu.)
RS-232C Serial Interface Settings
If the user sets the printer to use an RS-232C serial interface, the Configuration
Menu can be used to set the following RS-232C-specific settings:
♦
Set a baud rate of 115200, 57600, 38400, 19200, 9600, 4800, 2400, or 1200 baud
♦
Set the number of data bits to seven or eight
♦
Set the number of stop bits to one or two
♦
Enable or disable parity
♦
Set flow control to software (XON/XOFF) or Hardware (DTR/DSR)
♦
Set the printer to ignore data errors or print a “?” upon encountering an error
The settings used will depend on the software the operator is using and the
capabilities of the host computer.
Diagnostic Modes
This function allows the user to put the printer into the following diagnostic
modes:
♦
Normal Mode:
this is the normal operating mode of the printer.
♦
Datascope Mode:
the receipt printer prints incoming commands and data in
hexadecimal format.
♦
Receipt Test Mode:
the receipt printer prints two code pages.
♦
Slip Test Mode:
the slip printer prints two code pages.
♦
MICR Test Mode:
the receipt printer prints all characters recognized by the
MICR.
♦
Check Flip Test Mode:
the check flip mechanism will flip an inserted check.
These diagnostic modes are enabled or disabled by using the Configuration
Menu. See “Configuring the Printer,” for instructions on how to enter the
Configuration Menu.
Datascope Mode
Datascope Mode allows the user to test the printer's communications. When in
Datascope Mode the printer receives all communications, but instead of
executing the commands it prints them out on receipt paper as hexadecimal
numbers in the order received. For example, the ASCII character “A” is printed
as the hexadecimal number 41 and so on.
To run the Datascope Mode:
1. Enter the Configuration Menu. See “Configuring the Printer for instruction
on how to enter the Configuration Menu.
