3) VERIFY OPERATION
Once the module has been installed and configured per steps 1 and 2, verify the
module is operational by viewing the LED indicators.
The Power LED indicates the module is receiving power.
The Fiber Optic link LED indicates the fiber optic connection has been established.
Verify the serial port is configured for the correct mode of operation. Check the DCE/
DTE and TD/RD LEDs.

X21 Standalone Module USER MANUAL
®
The Omnitron
iConverter
X21 is a serial to fiber media converter featuring several
configuration modes enabling connection to a wide variety of X.21 and RS-530
applications. Data rates of up to 8Mbps are supported.
INSTALLATION PROCEDURE
1) Configure DIP-Switches
3) Verify Operation
1) CONFIGURE DIP-SWITCHES
FRONT PANEL DIP-SWITCH
SW1 - DCE/DTE
When this DIP-switch is in the "DCE" (default) position, the serial port is configured to
connect to a DCE device. When the DIP-switch is in the "DTE" position, the serial port
is configured to connect to a DTE device.
SW2 - SET CLOCK (RXC) POLARITY
When this DIP-switch is in the
Receive Clock "RC" (default)
position, the clock edge used
to sample the data on the serial
port is defined by the TIA/EIA-
SW1
334-C specification. When the
DIP-switch is in the Receive
Clock Inverted "Inv" position,
Down
the data on the serial port is
sampled on the inverted clock
edge.
The X21 supports standard DCE
sourced timing and terminal timing
modes. The included adapter cable
accommodates different connector
gender types. The X21 features
local loopback on the serial and fiber
ports to facilitate testing and
installations.
