Typical Machine Wiring. Typical RS-232 wiring - COM Port to CNC. CCI Fault Tolerant BTR wiring.The following diagrams depict the cable wiring between a DNC workstation'scommunications ports (either the standard built in COM1 and COM 2 or Rocketport expansionports) and most CNC's. The numbers given are for standard 25 pin D-subminiature RS-232connectors. On the PC side the connector must be a socket. On the CNC side it varies.FANUC and Yasnac's, for example require plugs. Okuma's and Cincinatti's generally requiresockets.If you are going to use the standard COM 1 and/or COM 2 ports that happen to be 9 pinplugs, we recommend using a 9 to 25 pin adapter so that all of your cabling can be alikeand that they can be more easily serviced when a data tester (break out box ) is requiredfor debugging.
We have, however, included wiring instructions for both 25 and 9 pinstyles. Of cable to useIn any factory environment shielded cables are essential. We recommend shieldedcables designed for RS-232 communications.
It is 24 AWG (American Wire Gauge) anddesignated as 'Low capacitance computer cable.' Sometimes you need onlythree conductors but other times you might need 5.

If there is ever a need to useRS-422 communications, such as, cable runs greater that 300' or very electrically noisyenvironment each signal requires a pair of wires. Therefore, we recommend using thefollowing:Overall foil shielded, 3 twisted pair, 24 AWG, stranded, low capacitance computercable. We use Carol CO901 or Belden 1420A. Connector at the P.C. And DB25 at theCNCThis wiringassumes the following:At the PC pins 3 and 7 are outputs.
Pin 5 is logic ground.Pins 2 and 8 are inputs.At the CNC pins 2 and 4 are outputs. Pin 7 is logic ground. Pins 3 and 5 are inputs.PC (25 Pin socket)CNC (25 Pin-as required)33 RXD22 TXD75 CTS84 RTS57 GND6Jumper pin 6 to pin 8 to pin 20.820Note!In general jumpering pins 6 to 20 together will suffice. For Fanuc CNC's jumpering all 3pins is required.Notes!Connect the shield on the P.C.
Side to the chassis of the PC or Rocketportadapter. This is easily done if you use a metal or metallized plastic connectorcover (hood) and make sure that the drain wire (thats an extra wire in a foil shieldedcable that is connected to the foil) or the braid of a braided type shielded cable makescontact with the connector cover.Typical parameter settings on the DNC side are as follows:Protocol: Generic RS-232Data rate: 9600 baud (CNC dependent )Data type: ASCIIParity: EvenStop bits: OneHandshaking: If Fanuc or Yasnac like CNC's, use'Both no wait'. The RTS signal from the CNC goes on at the beginning of any datatransfer, and off at the completion.
If not, you must choose the handshaking methoddepending upon the CNC. BTR wiringconnectors both endsThis wiring assumes the following:At the P. Pins 2 and 4 are outputs.
Pins 3 and 5 are inputs.
USB Connectors Pinouts & Cables There are many connector and cable options for the Universal Serial Bus, USB, the Universal Serial Bus each having standard pin connections / pinouts.USB Universal Serial Bus Includes:There are a number of different types of USB connector that are used on different types of equipment and in different situations. As USB has developed, new connectors have been introduced, generally reducing the connector size.Apart from the connectors that are standardised, the cable lengths are also defined: the maximum allowable length for an individual cable is 5 metres (3 metres for slow devices) and this allows the USB data acquisition module to be located remotely from the computer.Like all connectors, those used for USB have male and female versions to ensure that devices are mated in the correct direction. Type B USB connector USB upstream & downstreamIt is important to ensure that USB connections are made correctly and are able to follow the required protocols. To achieve this, USB remote devices have what is termed an upstream connection to a host. In turn hosts have downstream connections to remote devices.To prevent mis-connection, upstream and downstream connectors are not mechanically interchangeable.
This ensures that they can only be connected in the required direction, thereby eliminating the possibility of issues such as illegal loopback connections at hubs like downstream ports being connected to another downstream port.Until recently there was no peer-to-peer functionality. USB connector typesAs the concept of USB has developed, so too have the connectors. Data transfer speeds have risen, and the requirement for smaller connectors has increased.As a result there are seven USB connector types: Type A, Type B, Mini-A, Mini-B, Micro-A, Micro-B and Micro-AB. Types A and B have 4 pins within the connector, Mini and Micro A and B connectors have five pins. USB type A connector outlinesA USB cable can have one of two forms of connector in the original system. These are designated the 'A' and 'B' connectors.

The connections to the connectors are given below: Type A USB connector pinoutThe USB Type A plug is the male version of the connector. What might be referred to as the socket, is the female connector or receptacle, although it is often referred to as the port.The female connector or receptacle is the type found on the host, e.g. Computer, etc, whereas the male will be seen on items like flash memories, mouse connector, keyboard connector, etc.There is some colour coding on these connectors in terms of their capabilities. USB 3.0 Type A connectors are often, but not always, the coloured blue. USB 2.0 Type A and USB 1.1 Type A connectors are often black, but this is not always the case.USB type B connector outlinesA second connector type known as the Type B was often used for smaller peripherals. This had slightly different pinout arrangement. Type B USB connector pinout USB Type A & B pinouts / connectionsThe basic USB pinouts for the connectors are given in the table below.
Apart from the USB connector pinouts, the table also gives the wire colours used within the cables.Type A & B USB connector pin connectionsPinWire colourSignal Names1RedVbus (4.75 - 5.25 V)2WhiteData -3GreenData +4BlackGroundShellDrain wireShieldThe connectors used for USB are designed to enable the power and ground connections to be made first applying power to the device before the signal lines are connected. This prevents the possibility of the signal lines being connected first with the possibility of power being drawn through them that could cause damage to the device. USB mini connectorWith the reduction in size of many items of electronic equipment, even the Type-B connector was too large. As a result a USB Mini connector was devised and this is used on many cameras and mobile phones where space is at a premium.

Two versions are available, namely the USB mini-A and the USB Mini-B.These USB mini connectors, both the Mini-A and Mini-B provide very compact connectivity, while also being able to provide a robust connector solution. The Mini-A and Mini-B plugs are approximately 3 by 7 mm USB micro connectorWith space being even more confined on may items like today's modern cell-phones, an even smaller connector solution was needed and accordingly developed.Known as the USB micro connector, again both USB Micro-A and USB Micro-B versions are available.The Micro-USB plugs have a similar width and approximately half the thickness of their Mini-USB counterparts.
This enables them to be used in much thinner items of electronic equipment.The micro-A connector is 6.85 by 1.8 mm and it has a maximum over-mould size of 11.7 by 8.5 mm. The micro-B connector is 6.85 by 1.8 mm and this one has a maximum over-mould size of 10.6 by 8.5 mm.There is also a Micro-AB receptacle (socket) that can mate with both USB Micro-A and USB Micro-B plugs.The USB Micro connector has been adopted by many organisations as a standard.
The Open Mobile Terminal Platform, OMTP, endorsed Micro-USB as the standard connector for data and power on mobile device. Also the International Telecommunication Union, ITU, announced that it had embraced micro-USB for its Universal Charging Solution, thereby enabling chargers to all use the same connector and allowing standardisation and for one charger to be used for multiple types of equipment, e.g. Phones from different manufacturers, etc. Mini and Micro USB connector pinoutsThe connector pinouts or pin connections for the mini and micro USB connectors are given in the table below.

The different connectors also ensure that connections are only made in the right direction.
Although the number of USB connector and cable types is increasing, there is normally not to much of an issue in finding the right cable for connecting the right items together.
