EtherTRAK®2 and Etherbus®Dual Ethernet I/O Module3.3 RS485 Jumper on the E2-MIX20884-D baseOn the E2-MIX20884-D module has a jumper to set the RS485 termination instead of the “TERM” screw terminal on theother EtherTRAK-2 bases. The “storage” position should be used when termination is not required on the RS485 port.When a termination is used on the RS485 network and the EtherTRAK-2 is one of the end points the jumper should beput into the “termination” position. See below for a diagram of the jumper and RS485 equivalent circuit.ToRS485Device-+GNDEquivalentRS485 CircuitPhone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
