Printer Specification

An 80-column dot matrix printer with a serial

interface is required. The serial interface must be set,

using switches and/or jumpers with the following

parameters:

• 4800 baud

• 8 data bits, 2 stop bits

• No parity

• Hardware handshake using DTR/CTS. When

the printer is busy, it should force DTR, usually

pin 20, low.

• The printer must be capable of receiving at least

82 characters after a busy signal is sent (DTR

going low).

Readykey

have used the EPSON LX series and the

OKI Data Microline 182 printers successfully in the

past.

Baud Rate

You must make sure that the baud rate at the master

door controller is set to 4800. See the INST

command (see Section 6.1.5 INST Command).

Printer Cable

The following cable is required:

Use 24 AWG (0.5 mm), 4-conductor, unshielded

cable, maximum length: 50 ft. (15 m)

Testing the Printer

Once the printer is connected and the parameters set

as above, switch on the printer and make sure that it

is 'on-line'. If everything is set correctly, you should

immediately get some transactions printed out. If

not, pres the reset button on the controller.

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).

6.2.2 PC Interface Kit

Description

Readykey for Windows 16/32:

When an access control system is administered from a

PC, a PC interface kit is used to connect the PC to the

door controller. This involves connecting an interface

unit to the PC, along with a desktop key reader, and

connecting this, via a 4-conductor cable, to a small line

driver unit plugged into the door controller.

See the installation documentation for each

administration system for connecting the interface unit

to the PC and establishing communications.

This section describes the installation of the line driver

at the door controller.

You

cannot

use any other type of communications devices

such as line drivers, dial-up modems, etc

Cable Specification

Use multi-stranded, unshielded, 4-conductor 24 AWG (0.5 mm) signal cable.
