Refer to Serial Ports on page 43 for details on configuring RS-232 and RS-422 for the OEM6 family.
Each port may support some or all of the following signals:
• Request To Send (RTS) [COM1 and COM2]
• Clear To Send (CTS) [COM1 and COM2]
• Received Data (RX)
• Transmitted Data (TX)
All six COM ports on the OEM638 have all signals (TX/RX/RTS/CTS). In addition,
638
COM2 has DTR/DCD flow control signals.
If using the Ethernet connectivity, the distance between the RJ45 connector and the
628
magnetics must be no more than 10 inches (25.4 cm) and the distance between the
device and the magnetics must be no more than 1.5 inches (3.8 cm). The OEM638 and
638
OEM628 uses the Micrel KSZ8851SNLI device. Follow Micrel's recommendations for
transformer selection.
Port settings (bit rate and parity, for example) are software configurable. See Chapter 4, Operation OEM6
Cards and Enclosure on page 42
further information on data communications specifications and pin assignments.
OEM615 AND OEM617D RECEIVERS
COM1, COM2 and COM3 are CMOS LVTTL level I/O pins only. These ports require the addition of an
RS-232/RS-422 transceiver to provide appropriate signal levels. Most RS-232 or RS-422 transceivers
provide adequate ESD protection.
Refer to Section A.1.2, Logic-Level I/O and XXX for details.
