Device Port Interfaces
RS-232 RJ45 Interface
The device ports are located on the front of the EMG unit in the I/O module device port bays (see
).
All devices attached to the RJ45 device ports must support the RS-232C (EIA-232) standard. For
serial RJ45 device ports, RJ45 cabling (e.g., category 5 or 6 patch cabling) is used.
Serial RJ45 device ports for the EMG are reversed by default so that straight-through RJ45 patch
cables may be used to connect to Cisco and Sun RJ45 serial console ports. See
. The RJ45 ports have software reversible pinouts to switch between DTE and DCE
applications.
Note:
RJ45 to DB9/DB25 adapters are available from Lantronix. For serial pinout
information, see the
Appendix C: Adapters and Pinouts on page 409
Additional device port features:
RAW TCP, Telnet or SSH to a serial port by IP address per port or by IP address and TCP port
number
Simultaneous access on the same port - “listen” and “direct” connect mode
Device ports support the following baud rate options: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, and 921600 baud.
