Communications support
   

 

The Gecko processor supports general communications and custom network designs by providing interfaces to the two most common physical layers, RS-232 and RS-485.

RS-485

• Solder-bridge selectable 120R termination resistors.
• Solder-bridge selectable 2-wire (half duplex) or 4-wire (full duplex).
• Solder-bridge selectable 560R bias resistors.
• Connection to RJ45 8/8 socket through patch panel.
• Patch panel has access to various power options for power over network.
• Rx/Tx swappable under program control for auto polarity detection .
• ESD protection.

RS-232

• MAX232 chip
• 4 full spec signals, Tx, Rx, plus one control in and one out

There are screw terminal blocks for all RS-485 and RS-232 signals plus a patch panel allows any combination of RS-485 and power signals to be connected to an on-board RJ45 socket.
