Ethernet Modules.
The ethernet port of these
modules are not automatic
MDI/MDI-X crossover, but
the use of an auto-crossing
switch eliminates the need
to make a distinction between
straight-through and crossover
cables.

The ethernet port of the PC is
generally not automatic MDI/MDI-X
crossover and is wired MDI.
Because the Acromag ethernet switch
900EN-S005 is automatic MDI/MDI-X
crossover, use of a direct (straight-through)
or crossover cable is permissible.
IMPORTANT: IF THE HOST PC CONNECTS DIRECTLY TO THE MODULE,
YOU MUST USE A CROSS-CONNECT CABLE (MDI-X), AS BOTH THE PC
AND THE 9XXEN MODULE ETHERNET PORTS ARE WIRED MDI.
ETHERNET SWITCHES AND HUBS ARE WIRED MDI-X.
THE ACROMAG ETHERNET SWITCH IS AUTOMATIC MDI/MDI-X AND
ELIMINATES THE NEED FOR MAKING A DISTINCTION BETWEEN
THE USE OF STRAIGHT-THROUGH (MDI) AND CROSSOVER (MDI-X)
CABLE CONNECTIONS.

5-Port Ethernet Switch
or equivalent.
The ethernet ports of this
switch are automatic MDI/MDI-X
crossing and do not require
crossover cables.
USE OF AN ETHERNET SWITCH TO NETWORK
A HOST PC TO MORE THAN ONE MODULE
Acromag offers a straight-through patch cable (Model 5035-355), or a
crossover cable (Model 5035-360) for use with Series 9xxEN modules.
You can use this switch to build a network of Acromag Ethernet modules,
similar to that shown below. This drawing shows how to network-connect
this switch to a host PC and four Acromag Series 9xxEN Ethernet I/O
modules.

Connect 15-36V DC to the power terminals labeled DC+ & DC-.
Optionally connect redundant (backup) power to the second DC+
terminal. Observe proper polarity. For supply connections, use No. 14
AWG wires rated for at least 75
°
C.
CAUTION:
Do not exceed 36VDC
peak.

Connection to program port P1 is not required to achieve basic
operation.
Connection to this port is only required if you wish to make
use of more advanced programmable features of this device, such as
port-based VLAN support, broadcast storm protection, rate limiting, and
priority control. An optional accessory cable (Model 5035-365) and
software are required to interface with this port. This software is
included on the CDROM that contains this manual and shipped with your
unit, or it may be optionally downloaded from our web site at
www.acromag.com. Refer to the Technical Reference section at the
back of this manual for more information regarding advanced features
and optional program port connections.
