Standard Module
The standard version of the LK202-25/VK202-25
allows for user configuration of three common
communication protocols.
First, the unit can communicate using serial protocol at either RS323 or TTL
voltage levels.
Second, it can communicate using the Inter-Integrated Circuit connect, or I2C protocol.
Connections for each protocol can be accessed through the four pin Communication/Power Header as
outlined in the Serial Connections
and I2C
Connections
sections below.
Recommended Parts
Figure 5: Communication/Power Cable
(SCCPC5V)
The most common cable choice for any alphanumeric Matrix Orbital
Display, the Communication/ Power Cable offers a simple connection
to the unit with familiar interfaces. DB9 and floppy power headers
provide all necessary input to drive your display.
Figure 6: Breadboard Cable (BBC)
For a more flexible interface to the LK202-25/VK202-25
a Breadboard
Cable may be used. This provides a simple four wire connection that
is popular among developers for its ease of use in a breadboard
environment.
Serial Connections
A serial interface provides a classic connection to the
LK202-25/VK202-25.
The Communication/Power
Cable is most commonly used for this set up as it provides connections for DB9 serial and floppy power
cables. To place your board in Serial mode, adhere to the steps
laid out below.
1.
Set the Protocol Select jumpers.
?
RS232: Connect the three jumpers*
in the 232 protocol box with the zero ohm jumper resistors
provided or an alternate wire or solder solution.
?
TTL: Connect the two jumpers*
in the TTL protocol box.
*Note:
Jumpers must be removed from all protocol boxes save for the one in use.
