Product information
| Features |
|
| Opto-Isolation | The CS-428/9AT ISO Opto-Isolation protects up to DC 2.5KV between RS232 and RS422, RS485 sides. Opto-Isolation perfectly isolates two endpoints so devices are protected from unfavourable electrical conditions such as ground potential differences, lightning and line interference. This results in more stable and reliable communications. |
| What is Isolation? | When an electrical shock caused by power or ground is passed on to the system it can cause severe, if not irrecoverable damage. This can be prevented by using Opto-Isolation. In addition, isolation has other benefits by reducing problems caused by signal distortion and signal line impedance matching. |
| Auto RTS Control (Auto Toggling) | The CS-428/9AT ISO has a built-in hardware feature that performs automatic toggling to prevent devices from sending data simultaneously. This operation is crucial when multiple devices are connected to prevent electrical collisions that lead to errors and unstable communications. |
| Indepentent | No additional software is required for operation. With an easily accessible DIP switch you can configure the interface for RS422 or RS485. The CS-428/9AT ISO has high performance 2.5KV Opto-Isolation to protect your equipment. The terminal block and DB9 connector make it simple to physically connect. |
