RS-232C Users
The ZETA6104Õs
COM 2
port is factory configured for RS-232C
communication (use the left-hand pin descriptions). If you
do not
need to use RS-485 communication, you may ignore this section
and proceed to the Mounting instructions.
Heatsink
Remove the two retainer screws.
(one on the top of the chassis,
one on the bottom of the chassis)
Slide the chassis forward, then
away from the heat sink.
(follow the dashed arrow)
Be careful
not to catch
the 50-pin header clips
on the chassis.

NOTE
: Set the switches to ON (as illustrated) to use the internal resistors. Do this for a single unit or for the
last unit in a multi-drop only. If these resistor values are not appropriate for your application, set the switches
to OFF and connect your own external resistors. See page 8 for resistor calculations and wiring instructions.
COM 2 port for RS-485, set JU1-JU5 to position 1 (as illustrated).
COM 2 port for RS-232, set JU1-JU5 to position 3 (factory default).
RS-232: Leave JU6 set to position 3 (factory default).
RS-485: Set jumper JU6 to position 1
(disables power-up messages, error messages, & echo).
Set the jumpers.
Set the DIP switches.
Reattach the chassis and replace the two retainer screws.
4-wire RS-485, set JU7 to position 3 (factory default).
(4-wire is full duplex: transmit and receive at the same time)
2-wire RS-485, set JU7 to position 1.
(2-wire is half duplex: transmit or receive at any time)
