Ethernet / Modbus Connection, J2

This connector is used for Ethernet communications from the Turbo PMAC2 Eth Ultralite to a

PC or into an Ethernet network. The default IP address for all Delta Tau products with Ethernet

communication capability is 192.6.94.5 which can be changed with the proper software

provided by Delta Tau.

This port can support Modbus communication and act as either Server or Client on a Modbus

Network. There are four sockets available on this port and each can be configured as Modbus

Server/ Modbus Client / PMAC ASCII or PMAC INTR. If you want to use this port for

communication purposes with the controller, you need to set at least one of the sockets to

PMAC ASCII.

NOTE:

Delta Tau Systems strongly recommends the use of RJ45 CAT5e or better

shielded cable.

Newer network cards have the Auto-MDIX feature that eliminates the

need for crossover cabling by performing an internal crossover when a

straight cable is detected during the auto-negotiation process.

For older network cards, one end of the link must perform media

dependent interface (MDI) crossover (MDIX), so that the transmitter on

one end of the data link is connected to the receiver on the other end of

the data link (a crossover/patch cable is typically used). If an RJ45 hub is

used, then a regular straight cable must be implemented.

Maximum length for Ethernet cable should not exceed 100m (330ft).
