3.2.1.6 Testing the Printer
Once the printer is connected and the parameters set as above, switch on the printer and make sure that
is 'on-line'. If everything is set correctly, you should immediately get some transactions printed out.
3.2.1.7 Possible Problems
If you do not get immediate printing of events, check the following:
• Check the cable - it should be wired as described above.
• Check that the printer's serial port is being used. Most printers are sold with a parallel port as
standard - the serial port is supplied as an add-on option. There may be a switch that selects which
port the printer should use.
• Check that both the door controller and the printer are set to a baud rate of 4800. If you get random
characters on the printer, the baud rates may not match. The printer will usually have DIP switches or
jumpers that need to be set to give the correct baud rate. Always switch off the printer before you
change any settings.
• If you get normal printout but after one or two pages the lines break up or you get random characters,
the 'handshaking' may not be working. Check that the printer is using pin 20 for its DTR signal. Some
printers allow you to select a different pin number (often pin 11).
3.2.2 Line Driver
When a PC interface kit is used to connect the PC to the door controller a line driver is supplied for
connection to the door controller. This section describes the installation of the line driver at the door
controller.
For further details, see the documentation supplied with the PC interface kit.
3.2.2.1 Cable Specification
Use multi-stranded, unshielded, 4-conductor 24AWG/0.22mm² signal cable.
