Supported communication channels

For optimal performance, use a wired connection for computers that browse to the JCT.

Ethernet network interface card 10/100/1000 Mbps

Wireless IEEE 802.11 connection

4G Network

Notes:
  • JCT may run over a 3G network. However, browsing to the JCT over 3G is not recommended or supported.
  • High latency (also called lag or wait time) can cause the JCT to disconnect from the SCT computer.
  • Signal strength impacts the overall performance of the JCT. For the best results, ensure that you have a strong signal for your wireless connection.
  • To avoid slow performance, use a network with at least 20 mbps upload speed.

For more information on supported server platforms for installation of the JCT software, refer to the Metasys Server Installation and Upgrade Instructions (LIT-12012162) and SCT Installation and Upgrade Instructions (LIT-12012067).

Note: On any phone with an Android operating system, we recommend that you use a third-party keyboard for commanding. First, download and install a third-party keyboard of your choice. Then go to Settings > Personalization > Language and Input > Keyboard and Input Methods > Default and select the third-party keyboard you installed. The location for changing the keyboard may vary depending on your device.

Is the data shown in the JCT current?

No. The widgets, the Graphics Manager, and the Graphics Editor do not display data values. In place of current data values, Point Info displays. If Point Info displays, it validates that there is a point configured for the piece of equipment.

Why does my screen look different on different devices?
