Wiring
WARNING: Electrocution hazard. To avoid personal injury or death from electrocution, remove all sources of
power and allow stored energy to discharge before installing or removing equipment.
Notes
• Use a serial cable with a 25 pin, D-Sub male connector on one end. The cable can be purchased locally or
constructed using the DB-25 connector provided with the printer.
• Serial printer connections are power-limited and may or may not be supervised, depending on the control
panel.
• Locate supervised serial/USB printers in the same room as the equipment to which they connect.
• Locate unsupervised serial/USB printers in the same room and within 20 ft. (6.1 m) of the equipment to which
they connect. Enclose wiring in conduit or equivalent protection against mechanical injury.
• Serial connection requires UL Listed and CSA Approved shielded RS-232C cable. Cable length may not
exceed 50 ft. (15.2 m).
Serial cable requirements
• Shielded RS-232C cable, UL and CSA approved
• DB-25 serial connector (included with the printer)
