RS-232 Connectivity

Serial Port Configuration
The enhanced serial port on the Vista Turbo Series control operates at a speed of 9600bps. Earlier Vista series
panels used a speed of 1200bps. (Please note that 1200bps option has is no longer supported.) Depending on your
application, you may need to adjust the configuration of your printer, home automation system or external software
package to match the faster speed. Consult the documentation for your external hardware or software for directions
on how to do this. In some cases you may need to contact the vendor of this external hardware or software for an
update patch or driver.
Printer must be configures as 9600 Baud rate, 8 Data Bits, No Parity, and 1 Stop Bit.
Serial Port Connections
On all Vista Turbo Series panels, there are two methods of connecting to the serial (printer/automation) port:
NOTE: TB4 and J9 support WIN-PAK® and Pro-Watch®, however if you want to connect to a printer you must use
TB4 to get the printer DSR supervision ("Printer Off Line").
1. Flying leads from terminal block TB4 to a 9- or 25-pin serial connector.
2. The VT-SERCBL cable into header J9. This connector terminates in a 9-pin serial connector.
NOTES:
• To connect this to a PC, you must use a standard straight through serial cable with a 9-pin connector on the
panel end and the appropriate connector for your PC on the other end.
• The TB4 method is intended for permanent wiring, e.g. when connecting to WIN-PAK or Pro-Watch. The J9
method is ideal for direct-connect programming, where the serial connection being made is only temporary.
• When connecting via TB4, observe the TB4 pin configuration shown on the Summary of Connections label.
IMPORTANT: When connecting the VT-SERCBL cable into header J9, the red strip (pin 1) on the ribbon cable
should be on the left.
NOTES:
•
TB4 and J9 cannot be
used simultaneously. If
you are using one of these
connection points to
communicate with the
panel, you MUST
temporarily disconnect the
other wiring.
•
You cannot use WIN-PAK
or Pro-Watch and the
Printer at the same time.
You cannot simultaneously use a serial printer and Home/Facility Automation.
