Two 9-way D-type serial ports are provided which are RS232/TTL compatible. In addition, the module’s front panel screw terminals (T6 - T15) provide two RS485/RS422, 2- or 4- wire ports, giving a total of four serial ports. All ports can operate at speeds up to 115K2baud.
Various protocols are available (eg: Serial Modbus, Modbus/TCP, Ethernet IP etc) in addition to Serial Tunnelling. The 9461-ET is designed for Zone 1 hazardous-area mounting inside a suitable IP6x enclosure and has intrinsically safe ATEX and IECEx approvals with FM and CSA approvals pending.
The approvals cover both surface industry and mining applications. The design is based on a high performance ARM9 155MHz 32-bit RISC Processor (ARM926EJ-S).
