Xantrex Technology XG 850 manual Ethernet Enet or Gpib Connector Optional

Hardware and Connection Setup

Ethernet (ENET) or GPIB Connector (Optional)

The power supply can be programmed from a remote terminal using a General Purpose Interface Bus (GPIB interface) or Ethernet (ENET). If you have a GPIB or ENET card, see the XG 850 Watt GPIB and Ethernet Interface Option Operating Manual (Part number M370078-06).

The GPIB interface is an 8-bit parallel data bus having a host of bus commands for synchronization and up to one megabyte data transfer rate. Use standard IEEE-486, 26 AWG GPIB cable up to 3 metres length.

For connecting the power supply to ENET, use a LAN RJ-45 and RJ-45 STP, Cat 5 cross-cable 9.84 feet (3 m) in length or longer. Use a standard RJ-45 and RJ-45 cross-cable.

Multiple Power Supply Connections to RS-485 Bus

Up to 30 units may be connected to the RS-485 bus. The first unit (master unit) connects to the controller via any appropriate port, and the other units (slave units) are connected with the RS-485 bus via the J6 connector. All units connected together should also have unique multichannel addresses.

A standard straight-through RJ-45 ethernet network cable can be used to provide the connection between the power supplies. See Figure 5-13.
