The LVK204-25-422
provides an industrial alternative to the standard RS232 communication protocol.
Rather than single receive and transmit lines, the RS422 model uses a differential pair for each of the
receive and transmit signals to reduce degradation and increase transmission lengths. Power can be
transmitted at distance to a -VPT module or supplied from the immediate vicinity to a regular or -V unit.
RS422 signals are
available in a six pin connector as
described in the RS422
Connections
section.
RS422
Connections
The LVK204-25-422 provides a robust RS422 interface to the display line. For this interface, a series of
six wires are usually screwed into the RS422 terminal block provided. An alternate header is also
available to provide local power to a regular or -V unit. To connect to your LVK204-25-422, follow
the
steps below.
1.
Set the Protocol Select Jumpers.
?
RS422: The LVK204-25-422
offers
only RS422 protocol and does not require any jumper
changes.
2.
Make the connections.
a.
Screw one wire; sized 16 to 30 on the American Wire Gauge, into each of the six terminal block
positions.
When local power is supplied,
a floppy cable may
link to the alternate power header.
b.
Connect the Vcc wire to the positive terminal of your power supply and the GND terminal to
the negative or ground lead to provide appropriate power as in
Table 43.
c.
Secure the A and B wires to your non-inverting and inverting output signals respectively, while
attaching the Z and Y wires to your inverting and non-inverting inputs.
3.
Create.
?
In a PC environment, uProject or hyperterminal will serve to get you started. In addition, a
variety of application notes are also available in a number of different languages to aid in
development. Instructions for the former can be found below and the simple C# example at
www.matrixorbital.ca/appnotesis a great first reference for the latter.
