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.

3.2.2 External Relay Wiring Considerations
Components of external relay wiring are illustrated in Figure 4.
3.2.3 Communication Connectors
Communication to and from the unit is provided through two RJ-45 ports on the
rear of the CM9760-REL. The ports are physically referenced as IN and OUT ports.
The RJ-45 IN connector allows the REL unit to be connected to an appropriate
Sercom port on the rear of a CM9760-CC1 controller. This port is factory set for
RS-422 communications.
The RJ-45 OUT female connector on the rear of the unit is always configured for
RS-422 and is used for cascading subsequent REL units.
The RJ-45 connector pin-outs are illustrated in Figure 5.

3.2.3.2 RJ-45 Data Cables
NOTE:
or reverse cable for
Use the supplied “flipped”
all
data connections to the relay unit whenev er
possible.
Because both RJ-45 connectors have the same wiring pin-outs, they require the
same “flipped” cab le . In other words, the IN connector requires a “flipped” cable for
connecting the first unit to the CC1, and the OUT connector requires a “flipped”
cable for cascading other units. A “flipped” cable is as follows: Pin 1 of the cable at
one end becomes pin 8 at the other end. Refer to Figure 6.
Note that the active pin-outs are associated with the outer four pins; namely, 1, 2, 7,
and 8. All accessories on the System 9760 require that the “flipped” cable be used
to attach peripheral equipment. This includes the REL unit.

3.2.4 Power Connections
The CM9760-REL utilizes an auto-ranging internal transformer circuit that allows
input power to range from 100-240 VAC, 50/60Hz. Associated with the input power
is the power ON/OFF switch and the input power fuse. The fuse is easily changed
as illustrated in Figure 7.

3.3 SETUP
3.3.1 Preliminary Discussion
NOTE:
At present, 700 GPIs are
available per system node. This
limit must be kept in mind when
configuring cascaded systems.
Some devices utilize more GPIs
and therefore more F rame Address
Space than other devices.
NOTE:
Only one de vice type at a
time can utilize the same frame
start address.
FRAME ADDRESSES
The IRC, VCRC, and the CM9760-REL Relay Interface Unit, all use software GPIs
to activate control of external devices.
The number of GPIs required by each hardware device v aries. The number of GPIs
(General Purpose Interfaces) required by the REL is eight.
The address setting entered into the DIP switches, however, is based on what is
called a frame address.
There is a direct numerical relationship between GPIs and frame addressing, which
is as follows:
THE USE OF 32 GPIs SPANS ONE FRAME ADDRESS, REGARDLESS OF DEVICE TYPE USED (device types other than REL units also utilize GPI control).
Therefore a single REL, which uses eight GPIs, occupies only 1/4 of a frame address (refer to Figure 8).
This means that four relay units fit into one frame address space. T o uniquely identify and address REL units within this frame address space, two additional address
bits (sub-frame bits) are used (refer to Figure 10).
The frame address entered in the DIP switch for the REL (or any other device)
serves as a ST AR TING point f or the frame address space it needs. Once a starting
frame address is entered, the REL can be thought of as allocating for itself the next
eight GPIs or the equivalent 1/4 frame address space it needs to operate. The REL,
of course, is unique in that when you have an y grouping of REL units totaling four or
less, they will all more than likely share the SAME FRAME ADDRESS, and differ
only in their SUB-FRAME address bit settings.
Figure 8. Relationship of Frame
Address Space and
the Relay Interface
Unit
ADDITIONAL REMARKS REGARDING FRAME ADDRESSES AND GPIs
One frame address is equivalent to the use of 32 GPIs. With a total of only 700 GPIs
available, only 700/32 or 21.8 (rounded up to 22) frame addresses are needed.
Frame addressing starts at “0”, so frame addressing runs from 0 to 21, or 22 total.
The layout of all 22 frame addresses and corresponding GPI ranges can be found
in T ab le A.
THE RELAY INTERFACE MEMORY FUNCTION
SW3 DIP switch settings (SW3-3 through SW3-6) control what can be thought of
as the contact “memory” function for the REL unit.
One would normally expect that when power is cycled (via a power failure or front
panel reset) that the relay contacts would return to their default settings, which for
the REL, would be determined by the normally open, normally closed (N/O, N/C)
settings entered into DIP switch 2 (SW2-7 through SW2-10).
The additional DIP switch settings for the memory function allow you to ov erride the
default setting in the event power is cycled. With a switch setting of “1” (memory
enabled), the contacts (in groups of 16) will retain the contact setting they had at
the time power was cycled. For groups not enabled, the contacts will defer to their
default values (per DIP switch 2 settings) if power is cycled (refer to Figure 10).
Pelco Manual C538M-A (3/04) 11
NOTE:
Figure 9 does not necessarily represent the order in which
REL units are
physically
connected together (for that, refer to
Figure 14).
Figure 9
does
illustrate that fr ame
address settings:
(1) Must be unique for each unit.
(2) Must follow the working rules
listed.
When setting frame addresses on the front panel switches for a group of daisychained REL units, keep in mind a few working rules:
WORKING RULES
1. Start with frame address 0, which is associated with physical GPI 1, and work
sequentially forward until all relay interf ace units are accounted for . Insure that
frame address space is contiguous (see EXAMPLE ONE and TWO of Figure 9).
2. The physical order in which relay units are connected is irrelevant. In a cascaded situation, however , leftov er REL combinations using less than one frame
address space should be placed at the tail-end of allocated frame address
space.
3. Do not overlap frame address spaces (see EXAMPLE FOUR in Figure 9).
4. Do not leave any open frame address spaces in the layout (see EXAMPLE
THREE in Figure 9).
For explanatory purposes, the setup in Figure 9 is used again in other parts of
the manual to illustrate various aspects of REL configuration and setup.

3.3.3 Software Considerations
NOTE:
When writing macros to
control REL operation, keep in
mind the following:
The macro must reflect your actual
equipment configuration; if you
change the configuration, you must
adjust the macro accordingly. For
example, if a macro were written
to control three RELs in a daisychain configuration and one of the
RELs was subsequently removed,
then any previously written macro
that included these three RELs
would have to be rewritten to reflect that change. Similarly, changing the frame address setting of
any of the RELs is essentially the
same as physically removing it
from the configuration.
Access to the operation of specific devices connected to REL units using keyboards
commands or macro operations depends on the GPI and the specific GPI ranges
each REL unit is assigned. For this to be possible, the software GPI Define File
must be configured using the MGR program. What follows is a brief introduction to
the configuration of the GPI and COMM setup files that need to be programmed for
successful REL operation. This introduction ma y not address other items that might
be needed for your particular system operation. Consult your MGR manual and
associated software for other specific or detailed information.
On a PC and monitor containing the 9760 MGR setup program, start the program
and access the GPI File (GPI file). Refer to Figure 11.
Each GPI can control up to eight relays; w e theref ore need to configure eight GPIs
to control the 64 relays on one REL unit.
1. Program the logical GPI numbers for all the physical GPI n umbers that will be
used. In most cases it is advisab le to program the logical number to be equal
to the existing physical GPI number.
2. For each associated GPI defined, configure individual relays as momentary or
latching, depending on the application.
Latching . . .
If the box is checked, it is latching; otherwise it is mometary (refer to Figure 11).
3. Define operator access, save the GPI file, return to the MGR main menu screen
and press the tab to bring up the COMMS file (.SCP file). Refer to Figure 12.
4. In the COMMs file, assign an equipment number (PIN) of 17 to the port on the
CC1 that will be used for communicating with the REL. Set the communication
settings for 9600 baud and ev en parity. Save the COMMs file, bac k out of the
MGR program and transfer all appropriate configuration files to disk and load
these files onto the CC1 to which your REL configuration is attached. You
should now be ready to operate your REL via direct control from the CM9760KBD. For manual or automatic control of REL functions under macro control,
consult the appropriate sections of the MGR manual.

Physical installation of the REL unit is relatively simple, although v arious configurations are possible.
4.1 DIRECT RACK-MOUNT HOOK-UP
The REL unit mounts in a standard 19-inch rack and occupies only one RU (1.75"
or 4.45 cm) of rack space (refer to Figure 13).
4.2 REMOTE OPERATION
The relay unit may be mounted to something other than a standard 19-inch rac k by
relocating the rack ears to another position. If it is desired to place the REL unit
some distance from the controller (CM9760-CC1), the RS-422 communications
from the relay unit to the controller should not exceed 4,000 feet (1,219 m).
4.0 INSTALLATION
Figure 13. Unit Dimensions and Rack-Mount Installation
Pelco Manual C538M-A (3/04) 17
4.3 DAISY-CHAINING
Daisy-chaining occurs when more than 64 relays are required.
More importantly, each unit must be configured to ha v e a unique address, referred
to as a Frame Address. F rame addressing with respect to REL units w as discussed
in Section 3.3.1. What follows is a discussion about the ph ysical hook-up of multiple
REL units. System software supports up to 700 GPIs or 5,600 relays. Whether
daisy-chaining two or multiple REL units, the first unit is connected from its “IN”
connector to the CC1 and connected to the second unit through its “OUT” connector. Subsequent units are chained together in the same way.
NOTE:
Since VCRC units also utilize GPI addressing, they can be
bussed together with REL units.
THE DIAGRAM BELOW DEPICTS VALID PHYSICAL HOOKUP VARIATIONS
OF THE SETUP DISCUSSED IN FIGURE 9 (MANY OTHERS ARE POSSIBLE).
SINCE EACH UNIT HAS A UNIQUE ADDRESS, IT MAKES NO DIFFERENCE
WHERE, IN THE CASCADED CHAIN, A PARTICULAR UNIT IS LOCATED.
HOOK-UP (1) AND (2) BELOW DIFFER PHYSICALLY, BUT ARE OPERATIONALLY
THE SAME (SEE NOTE).
(REFER TO SECTION ON COMMUNICATION CONNECTORS)
Figure 14 illustrates the physical hook-up of two cascaded configurations, each
containing nine REL units having the frame addresses illustrated in Figure 9.
Note that the physical order that any unit has in the configuration is independent of
its frame/sub-frame address.
Also note that the remarks made in the previous section regarding RS-422 wiring
run distances applies here when considering cables distance runs between daisychained units.
SWAPPED OR REVERSE CABLES

(2)
NOTE: PHYSICAL LOCATION OF REL 9 IN (2) IS DIFFERENT THAN REL 9 IN (1),
BUT OPERATIONALLY THE SAME BECAUSE THE FRAME ADDRESS HAS
NOT CHANGED.

5.0 OPERATION
5.1 OPERATIONAL OVERVIEW
The basic function of the REL unit is to allow the user/operator to control various
peripheral equipment via relay contacts. Each REL unit processes and executes
only commands with addresses that match that of the RELs (frame address). When
an REL receives a command with an inappropriate address, it passes it on to the
next unit (if applicable) via its OUT port.
When power is first applied to the unit, RAM is cleared and initialization routines
are called. The power LED is lit, operational chips are configured, interrupt priorities are set and the Data LED starts flashing on and off at about 1/2 second
intervals (refer to Section 3.1.2, LEDs). The unit is waiting for its first valid command.
5.2 OPERATING THE CM9760-REL FROM THE CM9760-KBD
Direct control operation of peripherals attached to RELs from a CM9760-KBD is
relatively straightforward once you have determined which GPI to call and AUX to
activate. In the ne xt section, we discuss two methods f or obtaining this inf ormation.
Method 1 uses Figure 16 and Table A; Method II uses the CM9760-REL GPI/AUX
CALCULATOR only (ignore VCRC references on the backside of the calculator).
5.2.1 Information Retrieval
OUR EXAMPLE: Assume you ha v e five cascaded REL units and you wish to activate the peripheral device attached to relay 39 on REL unit 5.
What information do you need to know?
Where can you find the information?
First, you need to determine two things:
1. Which GPI to call of the 704 available.
2. Which AUX, associated with the GPI, to press.
Method I – Table A and Figure 15
Figure 15 is a physical representation of OUR EXAMPLE. We will also use it to
recap the information needed to perform the steps illustrated in Figure 16.
First, the GPI range. Ev ery REL unit is associated with a range of eight GPIs. In our
sequential run of cascaded units, REL 5 has a GPI range of 33-40. (Had we instead
been interested in REL unit 1, then the GPI range we would want would be 1-8).
The GPI range can be determined in a number of ways: (1) you ma y already have a
list or (2), you can match the frame/sub-frame address on the physical REL unit
with those listed in Table A and thus find the GPI range and (3), if you already know
the frame/sub-frame address, you can use Table A alone.
Starting on the left in Figure 15, you can follow the line to the right of GPI 37 over to
where it intersects with the AUX associated with relay grouping 33-40. GPI 37,
therefore, is the specific GPI we need to accomplish our task. Of eight AUX associated with GPI 37, we can see that AUX 7 is the one we need. F ollow the vertical line
from AUX 7 up to where it intersects the associated relay n umbers and you will find
number 39.

Method II – The CM9760-GPI/AUX Calculator
If we revisit the EXAMPLE just discussed and illustrated in Figures 15, we can
immediately find the information needed by direct read-off from the information
boxes on the front of the calculator.
Move the calculator wheel until the number “five” appears in the Relay Unit # box.
Go to the table to the right of that and locate relay 39 in the yellow highlighted bo x;
travel to the left along that row and read off GPI 37 on the GPI Range slot. Next,
read off the AUX needed by looking at the Associated A ux ro w and locate the Aux #
directly above 39. You no w hav e the inf ormation needed (call GPI 37, press AUX 7)
to operate the desired relay from the 9760-KBD . Once the GPI and AUX inf ormation
is at hand, control from the keyboard is easy. (Refer to Section 5.2.2, KEYBOARD
OPERATION.)
Other Operations Using the Calculator
The CM9760-GPI/AUX Calculator comes in handy for oper ations other than obtaining the information needed for direct keyboard control operations.
Other uses might include the following:
1. As a reference for setting frame/sub-frame address s witches when installing a
group of cascaded REL units in a system installation. J ust displa y each Rela y
Unit # in the order it is installed (1-5, say) and at each setting of the wheel,
read off the frame/sub-frame Dip Switch readings and set the corresponding
switches on the REL unit itself.
2. If you need to know the GPI range of a particular unit, move the wheel until the
unit’s DIP switch settings match those that appear in the calculator’s frame/
sub-frame address boxes. Directly read off the GPI range for the given REL
unit.
3. Check on the validity of a GPI call.
4. Use the wheel while programming GPI and other related files to double-check
the relationship of the GPIs being defined with respect to the relay actually
being set up for use on which unit.
5. As an information source in troubleshooting situations.
5.2.2 Keyboard Operation
Using the specific GPI/AUX information obtained via Method I or Method II, it is
possible to control the desired peripheral device from the CM9760-KBD.
Below are listed the steps needed to utilize this information for direct control operation from the 9760 keyboard.
Pelco Manual C538M-A (3/04) 21
NOTE:
Figure 16 uses the setup
configuration of Figure 9 to illustrate
the steps involv ed to activate rela y
39 output on REL unit 5.
Once the system is running and a keyboard is on-line, direct control of an REL is as
follows (refer to Figure 16):
1. From the Default menu, use the keyboard keypad to enter the GPI number
that contains the relay output you wish to activate (data obtained via Method I
or Method II).
2. After entering the desired number, press the GPI button to bring up the GPI
sub-menu.
3. The GPI sub-menu shows the first six of eight auxiliary function icons, corresponding to six relays associated with the selected GPI. Press the MORE
button to see the remaining two.
4. Press the appropriate AUX function button directly below the desired A ux icon
to activate the relay and associated peripheral device.
5. Repeat steps 1 through 4 to control additional devices.
