| 5 | | For normal environments, [http://trac.factoryswblog.org/wiki/CableRj I like using RJ45 cables to connect my CANOpen equipment]. If all CANOpen equipment had dual RJ45 jacks, connecting the devices together would be easy. Unfortunately, many devices aren't available with dual RJ45's. For example, older AMC servo drives use a single DB9M, the IMS MDrives use a single DB9M (Plus, Plus2) or M12 (Plus2-65), and most CAN interfaces use a single DB9M. My approach is to convert all the other devices to use dual RJ45 jacks. |

| | 7 | My approach is to convert all the other devices to use dual RJ45 jacks; for DB9M-equipped devices, that means using a DB9M/RJ45 Modular Adapter connected to a RJ duplex (tee) adapter. The advantage is now all the equipment has the same configuration: dual RJ45 jacks. So it's easy to put any device anywhere in the network. The first and last devices have RJ45 terminators. |

| | 9 | If you have only one or two devices with DB9M connectors, then you don't need to use the RJ45 duplex adapters. You can use the DB9/RJ45 Modular Adapter with a DB9 pass through terminator such as [http://stores.can-connection.com/-strse-77/CAN-Terminator--dsh--pass/Detail.bok this Ixxat model], which looks nice but is a little pricey at $25. For example, a system with a DB9 CAN interface, three Copley Accelnet Panel drives, and a IMS MDrive 17 Plus could be connected like this: DB9 CAN inteface DB9 is connected to the DB9 pass through terminator connected to a RJ45 modular adapter connected to RJ45 patch cable connected to Copley 1 connected to patch cable connected to Copley 2 connected to patch cable connected to Copley 3 connected to patch cable connected to RJ45/DB9 adapter connected to DB9 pass through terminator connected to the MDrive. |

| | 31 | === Procedure === |
|---|
| | 32 | 1. If the modular adapter isn't a Norcomp RJADK09S7080831 or Pan Pacific ADM-9F8, then you need to determine which wires are connected to which pins. |
|---|
| | 33 | 1. With the contacts on the bottom, RJ45 pin 1 is the contact on the far right. |
|---|
| | 34 | 1. '''Carefully''' insert the crimped pins into the appropriate hole in the DB9F connector until they snap into place and won't come out. A small screw driver or insertion tool can help. |
|---|
| | 35 | 1. Be careful - so far in my experience, removing DB crimp pins is a huge pain. If you don't have the proper tools, it's just about impossible. Even with the correct crimp pin removal tool, it is not easy -- don't expect your removal tool to last very long. |
|---|
| | 36 | 1. Test the adapter in your CANOpen network. |
|---|
| | 37 | 1. Once you've verifed it works, chop off the extra wires. |
|---|
| | 38 | 1. Snap the DB9F connector into the backshell, pushing the the wires into the backshell. |
|---|
| | 39 | 1. Test again |
