| With
Serial Port Monitor, you can capture binary data from the computers
serial port, and with the use of a serial to parallel converter, you
can capture the data from the printer port of another device. It is useful in capturing data from devices that do not have the ability to "print to file". Key Features:
Serial Port Monitor fills a need where the device being captured is either proprietary, or does not have the ability to print to file. It can even capture data from your own computer for software that insists on printing to LPT1:, with the use of a parallel to serial converter. What you will need:First, you will need to
determine if the device qualifies to be connected to. Do not guess or
experiment with the ports of an undocumented device. The 9 and 25 pin
connectors are commonly used for all types of interfaces and aren't
always serial or parallel ports. In general, if the device was already
connnected to a printer, then you can connect it to Serial Port
Monitor. A tool, called a "breakout box" can be used to determine if a
port is a serial port. Do not use Serial Port
Monitor as a breakout box. When the signals are in their inactive
state, the line voltage is NEGATIVE (-) 12 volts, which could cause
serious damage to incompatible ports. In addition to Serial Port Monitor, you will require hardware to connect the sending device to the receiving PC. The cables, adapters, and optional parallel to serial converter are avalable at your local computer store or at various internet stores. If the sending device has a
parallel port, you will need a parallel to serial converter. The serial
connection on this converter becomes the "device" in the following
table. If the device is
transmitting its data directly out its serial port, use the table to
assist in determining the type of connecting hardware. The table
assumes that devices wired as Data Terminal Equipment, or DTE, have a
male connector and Data Communications Equipment, or DCE, have a female
connector. Be careful of certain
Parallel to serial converters. Often they can be switched to be DTE or
DCE, but of course the connector will remain the same, which will
require a gender changer for the device if the combination of switch
setting and connector gender deviates from the standard of DTE=male and
DCE=female. Also, be sure to select one that is primarily
a parallel to serial converter instead of a serial to parallel
converter. This will save you a lot of trouble with cabling. In
particular, make sure the parallel end has a female connector, with
wire "ears", that accepts a standard parallel cable. Some devices, including the
PC, require the support of the DCD line. Most crossover/null modem
cables have special wiring built in to support it, but a straight
through cable does not. This is because a crossover cable is used to
connect 2 DTE devices and the DCD pin on a DTE is input only. For this
reason, if given the choice of using or not using a crossover / null
mode cable, choose to use one. Adapters that change the
connector type and/or gender do not change the DCE/DTE status of a
connection unless the adapter specifies it does, with a term such as
"null modem".
* Caution:
May be a parallel printer port. Never connect a parallel port directly
to a serial port. Consult the documentation for the device to verify if
its a serial port and if not,use a parallel to serial converter. Try before you buy! Download:
