The PC4400 module is used for sending serial
communications through an RS232 port to a local printer
for on site monitoring of the PC4020.
All programming of the PC4400 is done through the
PC4020.
The printer can be located up to 200 ft (61 m) away from
the PC4400.
An 80 character printer is strongly recommended.
Configuring the Printer
1. Serial interface
2. Baud rate = 300, 600, 1200 or 2400 (PC4020 default
setting = 1200 baud)
3. Parity = None
4. Character length = 8 bits
5. Auto line feed = Off
6. American/Canadian character set
7. DTR Protocol or XON/XOFF (by default the PC4020
sends DTR protocol)
The PC4400 comes complete with a DB-25 (male)
modular jack adapter, and a 6 ft (2 m) six wire extension
cord. A longer extension cord can be used if required,
up to 200 ft (61 m) maximum.
Power down the PC4020, PC4400 and the printer.
Connect one end of the extension cord into the PC4400,
and the other end into the DB-25 modular jack adapter.
Connect the DB-25 modular jack into the RS232 serial
port of the printer.
See the PC4400 wiring diagram.
Power up the printer, then the PC4020 and PC4400. If
the PC4400 is already enrolled and the printer is on line,
the PC4400 will begin transmitting to the printer.
Sample 1 is a printout from the serial printer.
Most actions on the PC4020 that require an access code
are logged to the event buffer, and are sent to the printer
(see Sample 2).
The partition labels, access code names and zone labels
can be changed in the PC4020. See “PAR NAME LABEL” in
the Programming Manual for programming partition labels.
See “EDIT CODE NAME” in the System Manual under [
✱
][5]
commands to program the access code names. See “ZONE
LABEL” in the Programming Manual for programming zone
labels. The printout will then be as Sample 3.
The PC4400 sends events to the printer as they occur.
If the printer is off line or disconnected, the PC4020 keeps
new events in memory until they are ready to be printed.
When the printer is brought back on line, the PC4400 will
send the new events to the printer. If 450 new events occur
before the printer is brought back on line (450 events =
75% of the buffer), the PC4020 will send the “Buf Near Full”
reporting code to the monitoring station. (See ‘Maint Rep
Codes” in the Programming Flow Charts for programming
the “Buf Near Full” reporting code). If over 600 events occur
before the printer is brought back on line, the oldest events
will be overwritten.
The PC4020 contains an event buffer which stores the last
600 events.
To print out the entire event buffer, enter the “Prn Entire
Buff” section in installers programming [
✱
][8][Installer’s
Code][3][0].
The printout will begin with the oldest event in memory and
end at the most recent one.
