PATCH232 Test Program
PATCH232 can assist in solving problems relating to speed, format and protocol as well
as being particularly useful for diagnosing intermittent problems.
System Requirements
MAXPRO-Net Server communicates with external devices and accepts commands from
external computers, keyboards, GUI's, access control systems etc. An on-board VGA
chip-set is included for displaying system configuration and diagnostic software. One
PCI Bus 8 Port Serial RS-232 COM card is included, providing for communications
between external devices, such as matrix switching sub-racks, pan/tilt and dome
receivers and keyboards. Keyboard and mouse included.
In order to use PATCH232, you will require an IBM compatible computer with two serial
communications ports (COM1 & COM2), preferably a portable unit. A Hard Disk Drive is
recommended if the recorder function is going to be used. A variety of patch cords and
adapters are usually required.
Overview
PATCH232 is a very useful service tool as it allows you to look at the data being passed
down an RS-232 link. This enables you to evaluate the data and check that what data
you think should be appearing is actually there. It also allows you to see any data
corruption, which can be very hard to find if you are not able to see the data. Another
very useful feature is the ability to insert a command in either direction. PATCH232 has a
recording mode that allows it to act as a data logger. This feature is handy for any
intermittent problems as you can leave PATCH232 to record all data passed over the
link, to be examined at a later date.
Instructions for Use
PATCH232 can be used at either end of the link. To connect the laptop remove the
cable going to the MAXPRO-Net
or High-Level Interface) and connect it using any necessary adapters to COM2 on the
laptop. Then connect COM1 of the laptop to the communications port on the MAXPRO-
Net
®
Control Computer using a NULL MODEM adapter or cable. When this is complete,
turn the power to the laptop ON and run 'PATCH232.EXE'. The program will then prompt
you for the required low level protocol, i.e. Baud rate (19200, 9600, 1200, 600, 300),
Parity (even, odd, none), Number of data bits (7 or 8) and the Number of stop bits (1 or
2).

19200, E, 7, 1
•
9600, E, 7, 1
These are indicative only, as most devices can be configured differently to suit the site.
Please check your documentation for the correct values if PATCH232 does not seem to
work.
