Figure 17-1: Event Log Printer Connections - ADEMCO VISTA-32FB Installation And Setup Manual

VISTA-32FB Installation and Set-Up Guide
1
The printer must be configured as follows:
•
7 data bits, even parity, 1 stop bit.
•
300 or 1200 baud (1200 required if alphanumeric pager interface is installed).
•
Hardware handshaking using DTR signal.
The 4100SM Module is supplied with a 10-foot RS232 cable. A longer cable or an extension
cable can be used if the VISTA-32FB and serial printer are separated by more than 10 feet,
but the total cable length should be less than 50 feet.
The 4100SM Module must be connected to the panel using the distance of the trigger cable. The
wires cannot be lengthened to mount the module in a remote location.
Most printers either ignore the CTS, DSR, and CD signals, or require them to be high (i.e., 3-
15VDC as measured on RS232 DB25 Connector Pins 5, 6, and 8, respectively, with respect to
Ground Pin 7). The 4100SM Module sets these pins high. If the printer being used will not
operate with these pins high, then clip the blue (CTS), white (DSR), or red (CD) jumpers on
the 4100SM Module to set the corresponding signal floating. Important pins on the RS232C
cable are Pin 3 (data out), Pin 7 (ground), and Pin 20 (DTR - ready).
The DTR signal, as measured at 4100SM TB1, should be high (9.5-14VDC) when the printer
is powered, properly connected, on-line, and ready to print. This signal will be low (0-
1.5VDC) when the printer is not powered, not properly connected, off-line, or out of paper.
The VISTA-32FB will not send printing data to the printer unless the DTR signal is high.

USING DTR SIGNAL
NOTE: IF EARTH GROUND FAULT SENSING IS ENABLED,
-YOU MAY GET AN EARTH GROUND FAULT INDICATION
IF YOU USE A PRINTER OR PC WHICH HAS A 3-PRONG
GROUNDED POWER CORD. IF THIS OCCURS, FIRST
VERIFY THAT PIN 1 (CHASSIS GROUND) IS ISOLATED
FROM PIN 7 (SIGNAL GROUND) ON THE 4100SM'S RS232
CONNECTOR (EARLIER PRODUCTION VERSIONS OF THE
4100SM-ADT HAVE AN UNMARKED, 3/8" LONG, BARE
WIRE JUMPER LYING NEAR THE PIN 1 SIDE OF THE
RS232 CONNECTOR WHICH MUST BE CUT TO ISOLATE
THESE PINS). THEN VERIFY THAT THESE PINS ARE
ISOLATED ON YOUR PRINTER'S RS232 CONNECTOR.
FOLLOW THE INSTRUCTIONS PROVIDED WITH YOUR
PRINTER TO ISOLATE THESE PINS IF REQUIRED.
