5.4 Connecting a User Port to a Printer
To connect one of the IRRInet-XL RTU RS-232 ports defined as User Port to a printer,
use either the FLN6457 or the FLN6458 cable. Since the printer connection is not
defined by the RS-232 standard, different printer manufacturers have their own
definitions for the connectors. Select the specific adaptor according to the functions
defined in your printer for the various pins.
If the FLN6457 cable (with female 25-pin D-type connector) is used, refer to the following
table:
RS232 Function 25-pin Female Used As Direction
RX-DATA 3 Printer Rx-Data To Printer
DTR 20 Printer Ready From Printer
GND 7 Ground
If the FLN6458 cable (with male 25-pin D-type connector) is used, refer to the following
table:
RS232 Function 25-pin Male Used As Direction
TX-DATA 2 Serial Data To Printer
CTS 5 Printer Ready From Printer
GND 7 Ground
