Quick Connect
Serial Connections
The serial interface provides a classic connection for RS232 or TTL development.
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.
2. Make the connections.
Disassemble the enclosure by removing four Phillips screws at the corners of the case.
Locate the green Communication/Power terminal block, and insert cable wires

, up to 17
AWG solid or 18 AWG stranded, using the Com/Power Pinout.
Tighten the M1.6 screws of the terminal block to secure the wires and assemble the enclosure.
3. Create.
Use uProject or a terminal program to get started, and then move on with your own
development. A number of application notes are availab

This time you're on your own. While there are many examples within the Matrix Orbital
AppNote section
too many controllers and languages exist to
cover them all. If you get stuck in development, it is possible to switch over to another protocol
on the standard board, and fellow developers are always on our forums for additional support.
*Note:
Internal headers other than the Comm/Power Connector are not available for the Enclosure Series.
**Note:
Jumpers must be removed from all protocol boxes save for the one in use.
***Note:
Matrix Orbital can design a custom cable for your enclosure, please contact sales for information.
