Serial Connector Pin-out
The host computer or serial converter device must incorporate a 9-pin
D-Subminiature RS-232 connector (DE-9). The cable to the ICE450 should
not exceed 20m for RS-232 applications. Note that many varieties of serial
converters are available from third-party suppliers to convert from RS-232
to RS-485/RS-422, USB, Ethernet and so on, depending on your interface
requirements.
The ICE450 requires only a minimal three-wire connection for RS-232
communications although a standard full DTE-DCE cable may be used in
most cases. A few things to note regarding the ICE450 DE-9 connector
interface include:
• A loop back jumper is pre-wired from RTS (Pin 7) to CTS (Pin 8).
• Pin 9 provides a +5V (100mA maximum) fused output in reference to
serial ground (SGND, Pin 5) for customer use.
