CONTROL Connectors
The CONTROL connectors on the UDM-RX02N include the SERIAL (RJ12) connector, the IR Rx
(IR receive), and IR Tx (IR transmit) ports.
SERIAL (RJ12) Port
The SERIAL (RJ12) port (FIG. 37) allows administrators to control the various functions to the UDM-RX02N
from a command line prompt and terminal connection.
Requires a DB9-to-RJ12 adapter cable (FG-RS01) to connect to a PC.
Default settings = 9600, 8 bit, No Parity, 1 Stop Bit.
The Serial port can also be used as a control port for sending serial data to a connected device. In this mode the
UDM-RX02N supports baud rates from 1200 - 115200. If a display device is controlled using a serial
connection instead of IR, then a serial cable is connected from the UDM-RX02N to the serial port on the
display device.
Depending on the screen manufacturer, it may be necessary to introduce a cross into this connection by instead
using the FG-RS02 cable, or a null modem DB9-DB9 adaptor with the FG-RS01. In some cases the null
modem adaptor may need a link between RTS/CTS at the DB9 end.
For example, NEC LCD panels act as DTE equipment and work with standard serial cable, while Fujitsu and
Panasonic Plasma screens act as DCE equipment and therefore require cross connections.
FIG. 38 describes the pinouts on the SERIAL (RJ12) connector.
The UDM-RX02N can be controlled via SEND_COMMANDS (UDM-0808-SIG), or via
the (optional) UDM-RC05 IR Remote Control (FG-UDM-RC05)

SERIAL (RJ12) Port
The baud rate on the UDM-RX02N must match the baud rate as the receiver is set up
for. For example, if the baud rate has been changed to 115200 for a certain display,
then you’ll need to change your terminal to the same 115200 baud rate.
Also note that you must type ‘setup’
within
30 seconds of powering up
- after this
time period, anything typed will be sent back to the UDM Hub.
