may be used to connect the modules to a standard serial port such as COM ports on PCs. To connect this
module to a PC, a 1 foot serial cable and a 4-BR cable are needed. These accesories can be purchased at
the following link: www.matrixorbital.com/pages/accessories.asp?CatID=5. This device complies with the
EIA232 standard in that it uses signal levels from +/-12V to +/- 12V. It will also operate correctly at TTL (0
to +5V) levels. To use standard RS-232 no modifications are required.

If a standard module is ordered a 5 Volt input must be applied. You have two options for this to be
If a wide voltage module is ordered a 7-15 Volt input must be applied. There is two options for this to
A 4 pin SIP connector can be connected to a Matrix Orbital supplied PC cable .
The RS-232 connector on the PC cable is wired so that a standard ’straight through’ 9 pin D-sub cable
NOTES
• A common ground should be used at all times.
• Each module ordered has specific voltages and cannot be interchanged.
