Interconnecting Multiple Units via SymLink
This is relatively straightforward, however the following points are important to
keep in mind:
• SymLink is a ring network unlike EtherNet which uses a hub and spoke
topology making a single connection to each device from the hub. Each device
on a SymNet network has two connections: TRANSMIT and RECEIVE. With
SymNet the last unit’s TRANSMIT connector must connect to the rst unit’s
RECEIVE connector.
• SymLink cables must be shielded, and are limited to 10 meters length (each).
• It is not necessary to follow any particular numeric order when interconnecting
units. This may be helpful when units are located in adjacent racks.
• Each unit must have a different Unit ID number. The master unit must be
Unit ID #1. Remember where this unit is, because the PC running SymNet
Designer must be connected there.
