CONNECTING TO THE RS-232 PORT
Connection is made with a null-modem serial cable with a DB-9
male plug to the CM16a. The
RS-232
port can be used for setting
various operational parameters that are CRITICAL to proper
operation of the CM16a. The network address settings can be
changed through this port.
Do Not Change the Network
Address unless you are certain of what you are doing!
Refer to Section 3
(page 27) for more information.

CONNECTION TO 10BASE-T (network connection)
Connection to the Ethernet network is made using the RJ-45 type
connector labeled
10BASE-T
on the rear panel.“RJ-45” is the
standard network connector for Ethernet networks. Insert the RJ-
45 plug into the receptacle with the lock-tab oriented toward the
bottom of the CM16a and push firmly until the connector locks
into place (usually an audible “click” can be heard). Refer to
Section 1 of this manual for Ethernet connection schemes and
cabling. If the CM16a is connected
directly
to the system control-
ler computer’s network interface card, a
crossover
type cable is
required. All other connection methods utilize normal Ethernet
cabling.
CONNECTING TO 4-CHANNEL AMPLIFIERS
Two basic rules must be adhered to:
First
, both DataPorts of the amplifier must be used.
Second
, both must be connected to the same CM16a.
If only one DataPort connection is used, the CM16a will not
control or monitor the amplifier correctly (the same applies for
connecting the two amplifier DataPorts to two separate CM16a’s;
the system will not function properly). Insure that both amplifier
DataPorts are used and that they are connected to the same
CM16a. You do not have to use adjacent ports on the CM16a (i.e.
PORT C
and
PORT D
). You can use any two ports for convenience;
the only impact of doing this is that the System Manager
software control panel will not show all four channels next to
each other.
CONNECTING TO 2-CHANNEL AMPLIFIERS
2-channel amplifiers require a cable connection from the amp’s
DataPort to the appropriate
PORT
receptacle on the CM16a.
These HD-15 type connectors are labeled
PORT A
through
PORT
H
. Use standard 15 pin VGA monitor cables (the same type of
cable that interconnects PC’s & monitors).
To connect the cable to the CM16a, orient the HD-15 connector
with its wider-side down (look at the connector, one side of the
plug’s metal surrounding is wider than the other) and align it with
the receptacle, then gently push into the receptacle until it is
firmly seated. Use the retaining screws on the cable ends to
secure the plug to the CM16a and the amplifer. Tighten “finger
tight” to avoid damage to the HD-15 receptacle. The same basic
procedure applies for connecting the other end of the cable to the
amplifier’s DataPort.
