1. Does your simulator work with third-party GigE Vision clients and SDKs? |
|
We tested GigESim against several third-party GEV clients/SDKs and they worked with no issues. However we recommend using our ActiveGigE SDK on the client
side as it offers functionality not available in other SDKs. One good example is JPEG compression available in both GigESim and ActiveGigE. |
|
|
2. Do you offer a discount on a combined purchase of GigESim and ActiveGigE? |
|
Yes we do. You will receive a 20% discount in comparison to the sum of individual orders. |
|
|
3. Can I use GigESim on the same computer where my client GigE Vision application is installed? |
|
Yes, you can. Running both GigESim (GigEmulator) and your client software on the same computer is the most practical way of testing and debugging your GEV-compliant
application when an actual camera is unavailable. |
|
|
4. I am running GigEmulator and my viewer on the same computer, and I am getting the black screen with no video frames coming. |
|
Make sure to go to your network card properties and disable a network filter driver which your client software/SDK is using. If your client SDK is ActiveGigE,
disable GCAM GigE Vision Filter. Filter drivers are helpful when used with external video sources, but they block internal network traffic. |
|
|
5. ActiveGigE sees the simulator, but no video is displayed. What is wrong? |
|
Make sure to disable the firewall in your system. If this doesn't help, set the packet size of the virtual camera to 1500 bytes. |
|
|
6. I am getting a corrupted video stream. Image is broken in parts or frozen. Why? |
|
Your network adapters or network switch are not fast enough to support the requested bandwidth. Make sure to select the Jumbo option
in your network adapter configuration settings and set the packet size for both network adapters and simulator to at least 8000 bytes.
If your adapters or switch do not support Jumbo frames, you may need to replace them. |
|
|
7. I expect to get the transfer speed between GigESim and my client application close to 1 Gbps, but I am barely getting 50% of it. |
|
Your network packets are too small. Make sure to select the Jumbo option in your network adapters configuration settings and set the packet size
for both network adapters and virtual camera to at least 8000 bytes. If your adapters or network switch do not support Jumbo frames, you may need
to replace them. |
|
|
8. Do I always have to use Gigabit NICs when working with GigESim? |
|
No, you do not. GigESim will work with any network adapter, ranging from 100 Mbps to 10 Gbps. Make sure though to use a packet size
corresponding to your network configuration. If you are working with 100 Mbps NICs, your packet size should not exceed 1500 bytes. If you are using 10 Gbps NICs,
the packet size should be set to 16 KB. |
|
|
9. Can I use GigESim to create a virtual wi-fi GigE Vision camera? |
|
Yes you can. Connecting GigESim to a wi-fi adapter is no different from connecting it to a wired one. A client GigE Vision application executed on a remote
wi-fi equipped computer will be able to receive video from your virtual camera. However, you should consider bandwidth limitations of the wi-fi standard. For example, the
actual speed of 802.11g and 802.11n standards are only 20 Mpbs and 50 Mbps respectively. This limitation can be overcome by using JPEG or .H264 image compression formats
supported by GigESim and ActiveGigE. |
|
|
10. How do I use multiple virtual cameras at the same time? |
|
If you are using our GigEmulator application, you could simply run several instances of it. If you are integrating GigESim API into your own application,
you should instantiate several virtual camera objects, each one having a different serial number, MAC and IP address. |
|
|
11. Can I attach several virtual cameras to the same network card and have them stream video in parallel via a single Ethernet cable to another PC? |
|
Yes you can as long as each virtual camera is assigned a unique MAC and IP address. However, the total bandwidth will be limited to the throughput
of a single network connection. For high-performance multi-streaming systems we recommend using several network adapters. |
|
|
12. Can the IP address of my virtual camera be different from the IP address of the network adapter to which it is linked? |
|
Yes it can, but it should be in the same subnet with the IP address of the receiving network adapter. |
|
|
13. Can I purchase a run-time license and use it without purchasing GigE Vision simulation software (GSIM-DL)? |
|
No. Runtime licenses can only be used for additional installations and deployments. Your first purchase should always include GSIM-DL which comes with a developer license
allowing you to create your own virtual camera application. |
|
|
14. How many virtual cameras are covered by one runtime license? |
|
One runtime license covers one virtual camera. Additional cameras require additional runtime licenses. |
|
|
15. Can I transfer my license to another PC? |
|
Yes, if you purchase a USB dongle. Otherwise a license is computer-bound and non-transferable. |
|
|
16. How do I add adjustable features to my virtual camera? |
|
You do it by calling the CreateFeature function and processing ReadFeature and WriteFeature callbacks. Refer to GigESim User Guide for more details. |
|
|
17. I have read both the documentation and FAQ, and I still have a question. What should I do? |
