Summary of features
The ZP-EPC10 protocol converter is designed to convert control signals between
RS422 (full-duplex) and RS485 (half-duplex) protocol. In addition to adjusting for diffe-
rent pin assignments, the unit also converts the protocols used by the CEC C328 video
multiplexer and the SMD-type dome cameras manufactured by CBC. A single protocol
converter can support up to 31 dome cameras. It is also possible to cascade up to nine
protocol converters to control a maximum of 256 dome cameras using a single multi-
plexer.
Both SMD-type and CEC VSD-type dome cameras (only the former use RS485 proto-
col) may be operated jointly.
The following dome camera functions are supported:
❚Pan, tilt, zoom, focus, iris
❚Presets
❚Writing EEPROM
❚Start position (Home)
❚Auto-focus, auto-iris, manual iris control
❚Automatic pan or tilt function between presets 1 and 2
❚Control of pan and tilt speed
❚Camera speed control

Installation
zCaution!
The device is intended for indoor use. Do not expose it to either extreme tem-
peratures or extreme humidity at any time and choose its setup site accord-
ingly. The ambient temperature must fall within the range from 5 to 40 °C at all
times, the relative humidity of the air must not exceed 90 %.
❚Do not set up the device in the immediate vicinity of radiators or other heat sources.
Avoid sites which are exposed to direct sunlight.
❚Create sufficient space for lines and cables.
❚Ensure sufficient ventilation of the device.
❚For cable connections, use only cables which have been part of the delivery or are
otherwise suitable and which help to suppress electric interference.
❚When laying out the lines and cables, make sure that they cannot be easily damaged
and ease wherever possible tensile loads and stresses.
Connections
Dome cameras
Connect the dome cameras (maximum 31 cameras per converter) to the converter’s
DOME contacts.
Use Belden cables for connections if possible or twisted pair cables, based on the same
Belden standard.

Matrix switcher and further receivers or converters
You can lock the protocol converter in place on its own or as one of several devices into
a RS422 bus on the CEC C328 matrix switcher. The order or position of each of the sin-
gle devices has no particular effect because each device has its own address within the
bus system.
Installation

ZP-EPC10 9
(05/2000)
Installation
When the device is switched off, internal relays produce direct connections between
Command (Input) and Command (Output), as in between Answer (Input) and Answer
(Output) so that the signals are transmitted transparent between the remaining devices.
Use Belden cables for connections if possible or twisted pair cables, based on the same
Belden standard.
• Connect the CPU contacts with the RCVRS (J4) connection of the matrix switcher
when connecting the protocol converter directly to the matrix switcher.
• When positioning the converter anywhere in the RS422 chain, connect the CPU
contacts to the RCVRS contacts of the receiver or converter nearest to the matrix
switcher.
• Connect further RS422 receivers (e.g. CEC PTR or CEC VSD) or converters with
RCVRS contacts of the protocol converter.

Configuration
Termination
If you are using several units in a daisy chain configuration (RS422 or RS485), you must
terminate the end-connectors with a resistor equivalent to the cable impedance, otherwi-
se the system may not communicate properly.
The factory settings for the protocol converter are such that its RS422 connections are
already terminated. It is possible to bypass the terminal resistors, if you decide to chan-
ge your system to a different configuration in the future. Normally the TERM 1 switch
should be left in the ON position.
If the protocol converter is the first unit in the dome camera daisy chain (DOME connec-
tion), the TERM 2 switch must be in the ON position to terminate the daisy chain correct-
ly at this end. The last dome camera in the daisy chain should also have the terminal resi-
stor connected.
In an RS485 cascade, if cabling constraints make it impossible to connect the protocol
converter in the first position, then the TERM 2 switch should be in the OFF position
(down). The first and last dome camera in such a daisy chain must have their terminal re-
sistors connected.
Installation

ZP-EPC10 11
(05/2000)
Installation
Addressing
The system needs to be able to address every individual dome camera separately. This
is done by assigning a unique address to each camera in a daisy chain. The protocol con-
verter manages camera addressing for the multiplexer. Rotary selectors on the front pa-
nel of the converter are used to select an address area: two switches each are provided
for choosing a lower and an upper address; because hexadecimal coding is used, this
makes it possible to assign any address between 1 and 256.
A single protocol converter supports a block of up to 31 addresses. For this reason, the
values of the lower and upper address may not differ by more than 31. If a range greater
than this is selected, the unit will automatically change the upper address to: (value of the
lower address +31).
If it is desired to control more than 31 dome cameras, it will be necessary to cascade
several protocol converter. Assuming the first cascaded unit addresses 1 to 31 (i.e. lo-
wer address = 1), the subsequent unit will address cameras starting with 32 and so on.
If several protocol converters are cascaded together in a single system, the lower
addresses of consecutive units must differ by at least 31. If necessary, the protocol con-
verter assigns the upper addresses automatically.
zCaution!
If you connect several protocol converters in a cascade, ensure that each
address is used only once. If an address is duplicated, your system may not
operate properly.
The two rotary selectors on the left are used to set the lower address, those on the right
are used for the upper address. The address is coded in hexadecimal (if you are unsure,
see the conversion table in the Annex, page 14).
Example 1: Twelve cameras in the system, using addresses 1 to 12
Selector 1 to position 0, selector 2 to position 1 (= address 1)
Selector 3 to position 0, selector 4 to position C (= address 12)

12 ZP-EPC10
Example 2: 45 cameras in the system, using addresses 1 to 45
Cameras 1 to 31 are connected to the first converter, 32 to 45 are connected to a
second unit.
First converter:
Selector 1 to position 0, selector 2 to position 1 (= address 1)
Selector 3 to position 1, selector 4 to position F (= address 31)
Second converter:
Selector 1 to position 2, selector 2 to position 0 (= address 32)
Selector 3 to position 2, selector 4 to position D (= address 45)
☞Note:
Please refer to the system examples and explanations on page 15.
Switching on and off
Connecting to electrical power
Make sure that you have made all the other connections of your unit, before hooking up
the power supply as the last step.
Note that the protocol converter does not have a power on/off switch. Simply connect
the power supply to the protocol converter, and then plug it into the wall mains (power
socket). A red LED will light up on the front panel, indicating that the unit is ready for ope-
ration.
Function test
The CEC C328 video multiplexer has a large number of special features and different
modes. Once you have installed and set up your system, check all system components
to ensure that they are operating correctly.
As a minimum, you should make the following checks:
❚Selection of every camera connected to the system
❚Correct operation of functions controlled through the video multiplexer
❚Correct execution of programmed functions (e.g. pre-programmed camera positions)
❚Correct execution of automatic functions (e.g. auto-pan)
