5.2 SynqNet Onboard
Connection to the SynqNet Network can be made using the X5 (in port) and X6 (out port).
5.3 Synqnet Cables
You can connect to the SynqNet network using RJ-45 connectors.
5.3.1 Recommended SynqNet Cabling
The following is recommended for SynqNet Cabling:
l
Use shielded category 5 cabling.
l
The RF immunity of 100BT networks when using unshielded cable is moderate. Kollmorgen recom-
mends that only shielded cabling is used.
l
Braid + foil shielding is the most effective, but foil + drain wire shielding is acceptable.
l
If unusually high levels of interference are generated by the machine or nearby equipment, consider
using shielded cables with built-in ferrites.
l
Ensure that each SynqNet node is effectively grounded, which implies connecting a short fat strap to
the machine chassis or busbar.
l
There is no minimum length requirement for 100BT cables. However, cables must not be longer than
100m. Longer links are possible over copper using repeaters or over fibre using media converters.
Contact the cable factory for further information.
l
The machine chassis must be effectively bonded together. This is particularly important when using
SynqNet nodes that do not have independently shielded IN and OUT ports.
l
Be sure to take the usual precautions to secure the cabling so as to avoid chafing and fatigue.
l
High flexure cables are required for cable retractors. Only two signal pairs are needed.
l
Do not use cable couplers. Commercially available units generally have poor shielding and are con-
sequently an EMC hazard.
l
SynqNet is not compatible with standard Ethernet hubs or repeaters.
l
SynqNet does not support POE (Power-over-Ethernet).
5.3.2 Synqnet Cable Length
The SynqNet cable lengths are derived from the measured propagation delays during network initialization.
This information is used to determine the spacing between packets for each node. SynqNet networks can
have up to 32 nodes and cables can be up to 100 meters in length. By measuring the actual propagation
delays and optimizing the packet spacing, the network performance and actual bandwidth is improved.
