Installation
DTE and DCE
Each J/RS232-xx-01 model is configured as a:
•DTE (Data Terminal Equipment) with a male RS-232 port, or a
•DCE (Data Communication Equipment) with a female RS-232 port.
So, the type of media converter and the application in which it is used
determines which type of RS-232 cable is needed:
•Straight-through configuration cable, or
•Null-modem configuration cable.
NOTE: The J/RS232-xx-01 only uses pins 2, 3 and 5.
Install the RS-232 Cable
Sections 1-4 (below and on page 3) illustrate which type of RS-232 cable
should be used for the various applications:
1. J/RS232-CF-01 Media Converter / DCE Device
Use a null-modem RS-232 cable with a male connector when connecting
a J/RS232-CF-01 or J/RS232-CF-01(SC) media converter to a DCE device.

installed at both ends.
2. Connect the fiber cables to the first J/RS232-xx-01 media converter as
described:
• Connect the male TX cable connector to the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other J/RS232-xx-01 media converter as
described:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.

Power the Media Converter
NOTE: The external power supply provided with this product is UL listed by
the power supply’s manufacturer.
• Connect the barrel connector on the power adapter to the media
converter’s power port (located on the back of the media converter).
• Connect the power adapter plug to AC power. Verify that the media
converter is powered by observing the illuminated LED power indicator
light. (For DC power see the SPS1872-xx DC external power supply.)
