X21 Plug-in 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 8.192Mbps are supported.
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.
INSTALLATION PROCEDURE
1) Configure DIP-Switches
2) Install Module in the Chassis and Connect Cables
3) Verify Operation
1) CONFIGURE DIP-SWITCHES
FRONT PANEL DIP-SWITCHES
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-334-C specification.
When the DIP-switch is in the Receive Clock Inverted “Inv” position, the data on the
serial port is sampled on the inverted clock edge.
SW3 - DTE SET CLOCK (TXC)
POLARITY
When Terminal Timing mode is
enabled, this DIP-switch will determine
the clock edge used to transfer data.
When the DIP-switch is in the Terminal
Timing Clock “TTC” (default) position,
the clock edge used to sample the data
on the serial port is defined by the TIA/
EIA-334-C specification. When the
DIP-switch is in the Terminal Timing
Clock Inverted “Inv” position, the data
on the serial port is sampled on the
inverted clock edge.

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.
