FAQS
| Q: What took you so long? |
| A: I have been working on Greg's Boards for 10 years. |
|
|
| Q: What the heck is GAIO? |
| A: GAIO Stands for "Greg's Agile Input Output.
The pin configuration is conventional to standard Hobby servos often called
Airtronics, Futaba or JR. This being ground, IO, +5. The ground
pin is typically marked on the PCB and the +5 is always the middle pin
to protect inadvertent damage due to accidental reverse insertion of the
connector. Hobby Servos can be connected directly to a GAIO connector
on any of Greg's Boards.
Care should be taken to overload the +5vdc power supply on each board. Some of Greg's Boards have a 2-screw terminal connector to allow the use of an external power source for the GAIO connector. The GAIO connector will be one of two types. 1. Three .1 center pins or a 3-Pin Molex Type. On the 3-Pin Molex connector, pin 1 is the IO Signal and pin 3 is ground. |

| Q: What then is a GSIO? |
| A: GSIO is Greg's Serial Input Output. A
GSIO connector is typically an RJ45 connector used for the purpose of communication
between 2 or more of Greg's Boards or another computer.
GSIO connectorsl meet the RS232 three wire electrical standard by means of the MAX232 interface chip. Each connector can be programed to be "Master" or "Slave" depending on the setting of the Tx Rx jumpers. |

|
| Q: Why are there 2 GSIO connectors on my board? |
| A: Most of Greg's Boards that have a Serial Interface have two RJ-45 connectors to allow "ganging" or "daisy-chaining" multiple systems. Both GSIO RJ-45 connectors are identically wired (unless specifically marked) (ie: some of Greg's Boards have two RJ-45 Connectors that can be jumpered individually, see the documentation for the individual board. |

|
| Q: What is RJ45 Power? |
| A: Most of Greg's Boards that have Serial IO or
GSIO connectors for interboard communication. Greg has provided a
means whereby you can power your board from a GSIO cable. Each of
Greg's Boards that has this feature will have jumpers to allow you to connect
or disconnect the RJ45 power.
RJ-45 Power can be used to source unregulated +12vdc from one of Greg's Boards to another. It is your responsibility to make sure that you do not overload the printed circuit board traces that are provided when using the RJ45 connector as a power source for other systems. |

|
| Q: What is the Pin Out of a GSIO RJ45 Connector? |
| A:
Pin(s) 3,4 -- RS232 Signal Common "ground" Pin(s) 5,6 -- RS232 Tx and Rx Signals (determined by jumper settings) Pin(s) 7,8 -- 12 vdc ground connection (if jumpered in) Greg has adapters available that can be purchased to convert the GSIO to Standard DB-9 male or female connectors. |
|
|
| Q: What is the 10-pin "Program" connector used for? |
| A: Most of Greg's Boards use the Basic Stamp have
a 10-pin male ribbon connector for programming and re-programming the Basic
Stamp (or other microprocessor) that is used on each board. See the
product documentation for further use.
Greg has adapters available that can be purchased to convert the 10-pin Ribbon Connector to Standard DB-9 female that will connect to a standard PC 9-pin serial port. |
