Technical Description

The CPS-1052 is constructed using two identical CPS-1050 PCB assemblies. The following descriptions therefore

only refer to the CPS-1050. Additional functions available on the CPS-1052 are provided by interconnection

between the two CPS-1050 assemblies and identical functionality could be obtained using two CPS-1050’s.

Power supplies:

The CPS-1050 does not have its own power supply, but uses either +10 Vdc or +12 Vdc power from the first

connected switcher through the remote control logic connectors PL 4 and PL 5.

Pins 1A on both connectors are joined and are the power supply pins for the panel. This is to allow the power

supply to continue to the next control panel where more than one panel is required.

The +12 Vdc input (the only supply required) is reduced to +5 Vdc by a three terminal regulator.

A number of 10 µF and 100 nF tantalum tag capacitors are located at key points in the circuit to suppress

interference on the DC rails. Should any of these fail they should be replaced by high quality tantalum tag

capacitors of at least 16 Vdc rating.

Switching Logic:

Control logic for each switcher module is performed by a Programmable Logic Array (PLA) which has been

programmed for the required operations. This component will only function correctly when loaded with the correct

program and is therefore only available through IRT.

Each module of the switcher group has two control connectors on its rear assembly.

They are labelled PL 4 and PL 5. For descriptive purposes PL 4 is called the “input” connector and PL 5 the

“output” connector.

The pins on these connectors have the following functions:

PL 4 PL 5

1A +12 Vdc NC

1B Ground Ground

2A Data 4 Data 4

2B Data 3 Data 3

3A Data 2 Data 2

3B Data 1 Data 1

4A Data 0 Data 0

4B Switch pulse in Switch pulse out

5A Busy out Busy in

5B Unlatch in Unlatch out

The CPS-1050 remote control panel also has PL 4 and PL 5 but Pins 1A on both connectors are joined and are the

power supply pins for the panel. This is to allow the power supply to continue to the next control panel where more

than one panel is required. This is necessary as the CPS-1050 does not have its own power supply, but derives its

power from the first connected switcher.

The 5 bit codes on Pins 2A to 4A represent the input selected. This code is in BCD (Binary Coded Decimal) where

the Data 0 to 3 represent the binary numbers 0 to 9 (Inputs 1 to 10 if Data 4 is 0 or Inputs 11 to 20 if Data 4 is 1).

The unlatch out signal is asserted by a switcher if any of its front panel switches is operated or if its unlatch in

signal is asserted. The presence of an unlatch in signal causes any switcher to release control of the data lines (if it

had control of them).

A switcher signals that it has control of the data lines by asserting busy out. Busy out also ripples busy in.

The operation of a push-button ripples unlatch to modules farther down the chain, causing any of them with control

of the bus to release it, and in so doing clear the busy line.

As soon as the requesting module sees its busy in line clear, it takes control of the bus and asserts its busy out. The

busy out signal then ripples up the chain causing any other modules release control (if they had it).

1050-cps & 1052-cps.ib.rev9.doc Page 6 of 16 17/10/2007

Configuration

A CPS-1050 remote control panel must be powered by either:

(a) Connecting its PL 5 to PL 4 on a powered 3000 series module (i.e. one of the switcher group or a

CDC-3060 logic control module).

or

(b) Connecting its PL 5 to PL 4 on another CPS-1050 or CPS-9001 that is configured as in (a).

or

(c) Connecting its PL5 to a 1 RU series 10 x 1 switcher.

Connection details are provided in the following sections.

Interconnecting control panels:

Note: All connections between PL 4, PL 5 and PL 6 connectors are on a pin for pin basis.

Cables may be wired using the connectors provided or may be ordered from IRT using the following part number:

GDW-3011 300 mm cable for joining modules in 1 RU frames.

Multiple 10 x 1 control: Control panels are looped by joining PL 5 (data out) on one CPS-1050 to PL 4 (data in)

on the next. Link LK 2 is set to out on each panel.

PL 5 on the last control panel is then connected to the first switcher to be controlled.

20 x 1 control: Control panels are looped by joining PL 5 (data out) on one CPS-1050 to PL 4 (data in)

on the next and setting link LK 2 out on the 1 to 10 panel and in on the 11 to 20 panel.

PL 5 on the last control panel is then connected to the first switcher to be controlled.

10 x 1 breakaway: Control panels are looped by joining PL 6 (data out) on one CPS-1050 to PL 4 (data in)

on the next and setting link LK 2 out on both panels.

In addition IC U 2 type 74HC365 must be fitted to the control panel on which PL 6 is

used. This is the control panel for the video switcher and PL 5 on this control panel is

then connected to the first video switcher to be controlled.

PL 5 on the other panel is connected to the first audio switcher to be controlled.

Interconnecting switchers:

For 3000 series modules see separate manual.

Power on reset:

Power on reset is needed so that at power on only one switcher or control panel drives the buss. LK 3 on each of the

3000 series Switcher Group or the CPS-1050 remote control panel is used to select which unit is in control at power

on.

If LK 3B is not installed and the control panel is configured to be for Inputs 1-10 then at power on that unit will

take control of the buss and select input 1.

In the case of a multi-panel set up all of the panels except one should have LK 3B installed.

Safety enable switching:

LK 3 has another function. If LK 3A is not installed then any CPS-1050 switcher will act as tally only -- the

operation of any of its buttons will have no effect. This feature may be used to provide a safety enable switch.

The metalwork for the CPS-1050 & CPS-1052 panel is provided with a 6.35 mm hole at each end of the panel so

that a toggle or push-button switch may be mounted.

This switch may be connected in place of link LK 3A.

In operation the panel will display tally only and the front buttons will not effect a change in switcher output unless

the enable switch is operated whilst the selection is made.

1050-cps & 1052-cps.ib.rev9.doc Page 7 of 16 17/10/2007

Multiple switcher set ups

Eurocard 3000 series switchers may be combined to form 10 x 1, 15 x 1 and 20 x 1 switchers. For details of the

inter-module connections and link settings required see 3000 Series Switcher Manual.

Link Settings:

LK 2:

Sets the crosspoint range of the control panel as follows:

1 - 10 OUT

11 - 20 IN

LK 3:

Local / remote control selection.

If the switchers on the front of this unit are to be active then install LK 3A, otherwise install LK 3B.

1050-cps & 1052-cps.ib.rev9.doc Page 8 of 16 17/10/2007

Wire per crosspoint operation

In most cases the BCD encoded remote control system offers the most satisfactory way of controlling one or more

switchers. There are however, situations where it is necessary to provide a wire per crosspoint access for control and

/ or a line per crosspoint tally system.

Both of these facilities may be made available on the 3000 series and the AVS-1210, AAS-1220, VA-400, VA-410,

AA-293 and AA-294 - for details see the manuals on these switchers.

The CPS-1050 module provides direct access to both wire per crosspoint control and individual tally outputs via

connectors PL3 and PL7 respectively. These connectors are not normally fitted to the CPS-1050 but may be ordered

as follows: RS532-080 HE14 16 way 2 row header straight PCB mount.

RS532-327 HE14 16 way 2 row IDC socket.

These connectors may be specified when ordering from IRT or may be obtained from RS Components direct.

In addition to these connectors RS Components have termination tools and HE14 connectors with crimp termination

instead of the IDC types supplied by IRT.

Connection pinout details are shown in the Installation section following.

When wiring the wire per crosspoint input a choice may be made between connecting directly to ground on pin 6B

or via LK 3 using pin 5B. If connection is made via LK 3 then a supplementary contact closure may be used to

enable or disable the remote control function as described in Safety enable switching.

The tally out indication is normally high (+5 Vdc) for un-selected inputs and falls to ground for the selected input.

Cable connections to switchers:

Connection to 3000 series Eurocard switchers:

Connection to the 3000 series Eurocard switchers is made using 10 way ribbon cables observing the direction of

PL 5 (out) connects to PL 4 (in) on either switchers or control panels.

The cables are wired on a pin for pin basis.

Before activating the switchers and control panels a check should be made of all link settings on both switchers and

panels to ensure that no conflicting settings are present.

Daisy chain wiring from the control panel to the switchers may be used for all normal requirements except audio

breakaway operation where it is necessary to provide separate connections to the audio and video switchers from

the two CPS-1050 PL 5 (out) connectors.

In all cases the number of switchers connected to one control panel should not exceed 10.

Connections to 1 RU series 10 x 1 switchers:

The AVS-1210, AAS-1220, VA-400, VA-410, AA-293 and AA-294 switchers may be used with the CPS-1050 and

CPS-1052 for 10 x 1, 20 x 1 or 10 x 1 with audio breakaway switching.

These switchers use a similar protocol to the 3000 series, but there are important differences which place limitations

on their use and preclude a simple pin for pin wiring system.

Each configuration of these switchers needs to be wired separately according to the following tables.

10 x 1 operation:

The following connection may be used to connect a CPS-1050 to the following combinations:

1 x VA-410

1 x VA-410 plus y x VA-400 plus z x AA-294 (where y + z <=4)

n x VA-400 (where n <=5)

1 x AA-293

1 x AA-293 plus n x AA-294 (where n <=4)

n x AA-294 (where n <=5)

y x VA-400 plus z x AA-294 (where y + z <=5)

The following cable is required between the first VA-410 or AA-294 and the CPS-1050.

10 x 1 Audio breakaway operation:

This accomplished by logic control in the two CPS-1050’s (or CPS-1052). Connection to the video and audio

switchers is made separately from each CPS-1050 PL 5 (out). The wiring to the switchers is as described above.

20 x 1 operation:

This requires a different program to be present in PLA U 1 of each half of a CPS-1052. This must be specially

ordered from IRT and details of connections will be supplied with the replacement PLA chip (CPS1050U).

A cable as specified above will be required between each 10x1 switchers and their respective PL 5 connector on the

CPS-1052. In addition a cable as specified below is required between PL 6 on each half.

Maintenance & Storage

Maintenance:

No regular maintenance is required.

Care however should be taken to ensure that all connectors are kept clean and free from contamination of any kind.

This is especially important in fibre optic equipment where cleanliness of optical connections is critical to

performance.

Storage:

If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed

plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be

included to deter corrosion.

Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures

should be followed when inserting or removing cards from these bags.

Warranty & Service

Equipment is covered by a limited warranty period of three years from date of first delivery unless contrary

conditions apply under a particular contract of supply. For situations when “No Fault Found” for repairs, a

minimum charge of 1 hour’s labour, at IRT’s current labour charge rate, will apply, whether the equipment is within

the warranty period or not.

Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on

components shall be extended by IRT only to the extent obtainable from the component supplier.

Equipment return:

Before arranging service, ensure that the fault is in the unit to be serviced and not in associated equipment. If

possible, confirm this by substitution.

Before returning equipment contact should be made with IRT or your local agent to determine whether the

equipment can be serviced in the field or should be returned for repair.

The equipment should be properly packed for return observing antistatic procedures.

The following information should accompany the unit to be returned:

1. A fault report should be included indicating the nature of the fault

2. The operating conditions under which the fault initially occurred.

3. Any additional information, which may be of assistance in fault location and remedy.

4. A contact name and telephone and fax numbers.

5. Details of payment method for items not covered by warranty.

6. Full return address.

7. For situations when “No Fault Found” for repairs, a minimum charge of 1 hour’s labour will apply,

whether the equipment is within the warranty period or not. Contact IRT for current hourly rate.

Please note that all freight charges are the responsibility of the customer.

The equipment should be returned to the agent who originally supplied the equipment or, where this is not

possible, to IRT direct as follows.
