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.

iConverter 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.

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 Standalone Module and Connect Cables

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.

Figure F: LED Indicators

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.
