Manual Update: The CM9760-CC1 has been replaced with the CM9700-CC1 and the CM9760-MGR manage-

ment software has been replaced with the CM9700-MGR management software.

Keep the following in mind when referring to the instructions contained in these manuals:

• The CM9700-CC1 contains the latest CC1 software (version 9.01 or higher), and is
programmed with the new CM9700-MGR management software.

• Despite the difference in model numbers, the CM9700-CC1 functions the same as the
CM9760-CC1 and most of the information in these manuals applies to version 9.01 (or
higher) CPU.

•You can add the CM9700-CC1 to an existing CM9760 system if you upgrade the existing
CM9760-CC1 units with the current software (version level 9.01 or higher).

Software version 9.01 requires a minimum of 16 MB of RAM in the CPU. If required, you
can upgrade the RAM in older CM9760-CC1 units using the software upgrade kit
appropriate for your CPU.

• Do not use the CM9760-MGR instructions contained in these manuals. Refer to the
CM9700-MGR Getting Started Software Guide, on-screen help, or Online Help for
instructions.

1.0 GENERAL

1.1 IMPORTANT SAFEGUARDS AND WARNINGS

Prior to installation and use of this product, the following WARNINGS should be
observed.

1. Installation and servicing should only be done by qualified service personnel
and conform to all local codes.

2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X ,6 or
6P enclosure, it is designed for indoor use only and it must not be installed
where exposed to rain and moisture.

3. Only use replacement parts recommended by Pelco.

4. After replacement/repair of this unit’s electrical components, conduct a resis­tance measurement between line and exposed parts to verify the exposed
parts have not been connected to line circuitry.

The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage constituting a
risk of electric shock is present within this unit.

This symbol indicates that there are important operating and
maintenance instructions in the literature accompanying this
unit.

CAUTION:

RISK OF

ELECTRIC SHOCK.

DO NOT OPEN.

TO REDUCE THE RISK OF ELECTRICAL SHOCK,

DO NOT REMOVE COVER. NO USER-

SERVICEABLE PARTS INSIDE. REFER SERVICING

TO QUALIFIED SERVICE PERSONNEL.

CAUTION:

Please thoroughly familiarize yourself with the information

in this manual prior to installation and operation.

2.0 DESCRIPTION

The CM9760-REL Relay Interface Unit is an optional accessory of the System 9760®.
The relay interface unit provides dry contact switching for direct or automatic con­trol of peripheral equipment. The unit connects to any RS-422 COMM port on the
rear of the CM9760-CC1.

Some of the more important features of the CM9760-REL are as follows:

• Each unit provides up to 64 single-pole, single-throw (SPST) contact outputs
for operating different peripheral equipment.

• Relay output contacts may be configured for N/O (factory default) or N/C op­eration.

• With a handy “memory” feature , relay groups can retain or hold their pre-power
loss contact position in the event of a power failure or front panel reset.

• Multiple units may be cascaded to extend the number of rela y contact outputs
controlled from a single port on the CC1 (over 5,000 relay outputs can be
configured).

• The relay unit may be remotely placed up to 4,000 f eet (1,219.2 meters) from
the controller (RS-422 operation).

• The unit is powered by an auto-ranging power supply.

• The unit is a unique, one rack unit chassis (1.75 inches or 4.45 cm) accommo­dating multiple types of mounting.

3.0 PRE-INSTALLATION INFORMATION

3.1 FRONT VIEW AND DIP SWITCH ACCESS

Figure 1 illustrates a front view of the unit with its front panel removed. P ower (green)
and Data (red) LEDs occupy opposite ends of the unit’s front panel. As illustrated,
the removal of the five flat-head Phillips screws that hold the front panel in place
allow access to the units three DIP switches and the reset switch. All other s witches
and connectors are on the rear of the unit.

3.1.1 DIP Switches

The relay interface unit has three 10-position DIP switches that configure the com­munication parameters for the unit as well setting the parameters for relay contact
output operation. DIP switch functions are discussed in Section 3.3.2, DIP Switch
Settings.

3.1.2 LEDs

The green POWER LED located on the left side of the front panel of the unit comes
ON at power up.

The red DATA LED located on the right side of the front panel continually flashes on
and off at a regular rate (about 1/2 second intervals) until the first valid command is
received. The LED will not flash again until another valid command is received. In
cascaded configurations, each relay unit only indicates receiving data when the
data has the corresponding address of the unit. In other words, LED activity is
address specific.

In addition, if power is cycled, if a DIP switch slide switch position is moved, or if a
front panel reset occurs, the LED will again flash intermittently until the first valid
command is received.

3.2 REAR VIEW

The rear of the unit is illustrated in Figure 2. From left to right are the following:

1. Four blocks consisting of 16 contact pairs, each with mating plugs for the at­tachment of peripheral equipment. (Only the bloc k for the first 16 contact pairs
is shown with mating plugs.)

2. RS-422 input/output communication connectors (RJ-45 type).

3. One DB-9 connector (factory use only).

4. The grouped input power functions, consisting of input power terminals, a fuse
and an ON/OFF switch.

3.2.1 REL Contact Pair Connections

NOTE:

The numbers that appear
on the mating plugs in Figure 3 are
placed there for explanatory pur­poses only. The terminal positions
on the actual physical plugs are not
numbered.

Physically, each relay block consists of 16 relay contacts and two mating plugs.
Since a relay contact requires two terminal positions, each plug provides 8 contacts
via 16 screw terminals.

To determine the screw terminal pin numbers for a particular contact, refer to
Figure 3.
