EIA-485 Bridging Notes
Controllers with EIA-485 bridging capability will bridge • all MODBUS TCP
TM
communica-
tions arriving from the Ethernet port to the EIA-485 network.
Bridging must be enabled for the controller to send out e-mail, SMS, or SNMP traps trig-•
gered by the state of a device elsewhere on the network.
With bridging enabled, the DB-9 RS-232 connection on the controller cannot be used. •
EIA-485 and RS-232 ports share the same internal hardware and communication errors
will result.
Enabling bridging allows the controller to serve as a 485 master. •
Trendnet TE100-S5 Ethernet Switch Compatibility
The TS-MPPT-60 Ethernet interface will not work properly with the Trendnet TE100-S5 Ethernet
switcheswithoutawiringmodication.TrendnetswitcheshavetheirTx+andTx-lines,andtheir
Rx+ and Rx- lines, swapped. These switches may work with a PC because most computers sup-
port auto-polarity (automatic adjustment to this swapped polarity).
The TriStar MPPT Ethernet hardware does not support auto-polarity. This means that a wiring
modicationmustbemadeifyouwouldliketousetheTSMPPTwiththeTrendnetswitch.
One end of the Ethernet cable should have the following pinout:
