Introduction
This installation guide is designed for the use of persons concerned with the installation
and configuration of the protocol converter and any devices connected to it. Relevant
international, national and – if applicable – local electronic engineering standards should
be observed at all times.
Intended use
The ZP-EPC10 protocol converter is designed to provide an interface between the CEC
C328 matrix switcher and the dome cameras of the SMD series from CBC. The device
converts the data transfer between protocols RS422 and RS485. The unit is designed
exclusively for this function. No other application is permitted.

EU directives
The ZP-EPC10 protocol converter fulfils the specifications of European Union directive
89/336 (covering electromagnetic compatibility).
Identification plate
Precise identification of each unit is provided by the plates attached to the front and rear

Security Measures
Safety Measures
Danger by Electric Current
• The device must be connected to the appropriate power supply.
• Only use a suitable adaptor (see technical data).
• Disconnect the adaptor from the mains supply when an error occurs.
• Only use the adaptor and device in a dry, weather protected environment.
• If safe application of the device is no longer guaranteed, it should not be used but be
protected against inadvertent handling. Safe use is no longer possible, e.g.
– when the device or cables are visibly damaged,
– when the device does not work properly,
– when the device has been exposed to rain or wet conditions,
– when the item has been pierced,
– after prolonged storage in unfavourable conditions or after difficult transportation.
Have the device checked by CBC.
Installation
• When installing the device, electrical engineering regulations should be adhered to.
• Follow the instructions for installation and operation other equipment, e.g. cameras.
These instructions contain important advice on safety and approved use of equipment.
• Carefully follow guidelines for installation and use. Not doing this could lead to personal
injury, damage to property or to the equipment itself.
Repair and Maintenance
• Never open the housing of the protocol converter. The device does not contain parts
that you can repair or replace yourself.
• Ensure that repair or maintenance work is carried out by qualified personnel (electrical
engineers).

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
☞Note:
Observe the examples and explanations given from page 15 onwards.

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
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.
