INSTALLATION
Set Switches
Use a small flatblade
screwdriver or a similar
device to set the recessed
switches according to the
2-wire
site installation.
1. Set the 2-wire /4-wire
slide switch to the 4-
wire setting to enable the "receive – RS-485 4 wire, RS422 and receive +
RS-485 4 wire, RS-422" pair for RS-422 4 wire full duplex operation.
2. Set the RS-485/RS-422 slide switch to the RS-485 position to prevent
echo in two-wire mode. Set the RS-485/RS-422 slide switch to the RS-
422 to allow transmit only on "transmit/receive - (B) RS-485 2wire,
transmit - RS-422 and transmit/receive + (A) RS-485 2wire, transmit +
RS-422" pair.
Refer to the drawing and notes below for setting the 4-position dip switch.
* Position 1 ON inserts 130 ohm terminator on the "receive – RS-485
4 wire, RS-422 and receive + RS-485 4 wire, RS-422" pair.
** Position 2 ON inserts 130 ohm terminator on the "transmit/receive -
(B) RS-485 2wire, transmit - RS-422 and transmit/receive + (A) RS-
485 2wire, transmit + RS-422" pair.
*** Position 3 ON enables 1K ohm pull down on "transmit/receive - (B)
RS-485 2wire, transmit - RS-422".
**** Position 4 ON enables 1K ohm pull up on "transmit/receive + (A)
RS-485 2wire, transmit + RS-422
Install Slide-In-Module in E-MCC-1600 Chassis
NOTE: Media Converter Slide-in-Modules can be installed in any installation
slot, in any order.
1. Remove the Media Converter Slide-in-Module protective plate from
the selected installation slot by removing the two (2) screws that
secure the plate to the front of the E-MCC-1600.
2. Carefully slide the Media Converter Slide-in-Module into the
installation slot, aligning the Media Converter Slide-in-Module with
the installation guides.
NOTE: Ensure that the Media Converter Slide-in-Module is firmly
seated against the backplane.
3. Secure the Slide-in-Module by securing the panel fastener screw
attached to the Slide-in-Module to the E-MCC-1600 chassis.
DOWN=ON Inserts 130 resistor on "receive"*
DOWN=ON Inserts 130 resistor on "transmit"**
DOWN=ON Enables 1K "pull-down"***
DOWN=ON Enables 1K "pull-up"****

INSTALLATION
COPPER /DB-9 CONNECTOR
NOTE: Shielded cables are required on DB-9 for EMC compliance.
1. Locate or build TIA/EIA-574-DB-9 compliant cables configured as
shown on page 7, with a male DB-9 connector at one end of the
cable and with a straight-through cable.
2. Connect the male DB-9 connector at one end of the cable to the
Media Converter female DB-9 connector.
3. Connect the other end of the cable to the node device.
COPPER /TERMINAL BLOCK CONNECTOR
1. Locate or build TIA/EIA-574-compliant terminal block cables
configured as shown on page 7 and with straight-through cable.
2. Using a small flatblade screwdriver or a similar device, release each
terminal block installation location as necessary. Refer to the
diagram on page 7, connect the wires at one end of cable to the
Media Converter terminal block connector.
3. Connect the other end of the cable to the node device.
FIBER
1. Locate or build TIA/EIA-574-compliant fiber cable with male two-
stranded TX to RX connectors at both ends.
TX
RX
2. Connect the male TX and RX cable connectors at one end of the
cable to the TX and RX female connectors, respectively, on the
Media Converter.
3. Connect the male TX and RX cable connectors at the other end of
the cable to the RX and TX connectors of the IEEE 802.3™
compliant fiber device.
Connect to Power
The Media Converter is powered by the E-MCC-1600.
