PRINTER HOOKUP:
When connecting the unit to a printer, you must first program
the desired baud rate, parity and strobe list with a computer.
After the unit is programmed it can be connected to the printer.
Connect the transmit line(s) of the unit to the receive line(s) of
the printer and be sure that both devices have common
grounds. When the strobe line is triggered the unit will transmit
the selected strobe list which you had previously pro-
grammed.
