Product – ADC v11 and v12

Topic: Evertz 1200 Series 12x2 Routing

Switchers

This document describes the setup and use of the Evertz 1200 series routers in the ADC-100

environment. The modified GVG TEN-XL ASCII command protocol is used to control the Evertz

1200 series routers.

There are some hardware differences between the 1200 series routers and the Grass Valley

TEN-XL routers that have required differences in implementation of the protocol for the 1200

series routers. Since the GVG TEN-XL protocol is based on 10 input crosspoints and the Evertz

12 x 2 router family contains 12 input crosspoints, the protocol was extended to include

crosspoint #11 and #12.

Additionally, the 10XL protocol was originally designed to support an RS-485 bus containing a

number of 10x1 switchers. While it is not recommended to connect devices to ADC-100 in an

RS-485 configuration (there is no support for flow control on the Device Server), this driver

supports the concept of addresses for the purpose of directing commands to one of the two

destinations.

Device Set-up

The Evertz 1202S-AES router requires internal configuration for RS-422 communication. Consult

the manufacturer’s manual for other 1200 series models. On the 1202S-AES, remove the screws

in the top cover to access the jumpers and ribbon cables. To configure the serial port for RS-422

communication:

1. Move the ribbon cable on J29 to J23.

2. Set the jumper on J26 to pins 2 and 3 (toward header J23).

The firmware must be configured with the appropriate communications parameters. On the front

panel of the 1202S-AES:

1. Press the Setup button and scroll down to REMOTE CTL. Press Select to enter the

remote control menu.

2. Scroll until Baud Rate is displayed. Press Select to enter the Baud Rate menu. Scroll

until you find 38400. Press Selectagain to activate the 38400 setting. Press Setup to

back out to the Baud Rate menu.

3. Scroll down to Serial Format. Press Select to enter the Serial Format menu. Scroll until

you find 8e1. Press Select again to activate 8e1. Press Setup to back out to the Serial

Format menu.

4. Scroll down to Serial Address. Press Select to enter the Serial Address menu. Set this

to the desired base address*for the low output of the router (the high output will be the

next consecutive number), and press Select. Press Setup to back out to the Serial

Address menu.

5. Scroll down to Serial control. Press Select to enter the Serial control menu. Scroll until

you find Slave. Press Select again to activate the Slave mode. Press Setup to back out

to the Serial control menu.

6. Scroll down to Protocols. Press Select to enter the Protocols menu. Scroll until you find

gvg ten xl ascii. Press Select to activate gvg ten xl ascii. Press Setup to back out to the

Protocols menu.

7. Press Setup twice to back out to the EXIT menu and select Save and Exit.

*IMPORTANT NOTE About the Base Address and Crosspoints: The ADC-100 driver supports

base addresses for the router between 0 and 63. This makes the driver appear as a 12x64 router

object, but the switcher will react to only two destination crosspoints: The base address

crosspoint (for the first output) and the next consecutive number (the second output). Other

commands with different destination crosspoints issued to the router will be ignored. Additionally,

the Evertz router begins at address (destination #) zero, and ADC-100 is one-based. This means

that a base address of 0 on the router is represented by destination 1 on ADC-100. If destinations

14 and 15 are configured on the ADC-100, for example, then the base address of the Evertz must

be set to 13.

Device Server Set-Up

To configure the Evertz 1200 series router on the Device Server, you need access to the Device

Server Configuration Utility:

IMPORTANT Configuration Note: When you have finished making changes on a configuration

screen, press Apply and all changes made upon the current configuration window will be applied

to the driver. Press OK, and any configuration changes made upon the various tabs will be

applied, however, the configuration window will close. Press Cancel and none of the

configuration changes will be applied to the driver and the configuration window will close.

1. From the File menu select the Configured Devices item to display the “Configured

Devices” window.

2. From the list in the right hand pane select “EVERTZ 1200” from the “Router/Switchers”

category. Use the mouse pointer to drag this item over the top of one of the icons in the

right hand pane that has the caption “NO DEVICE”.

3. Select the E1202 icon you just created and press the right mouse button to bring up a

menu. Select “Properties” from this menu, or simply double-click on the icon instead.

4. Select the General tab to set the other parameters. Each of these parameters is

explained below (always remember to click Apply if you have changed something on the

tab:

•Device Name: An identifier up to 16 characters that is displayed in the device status

window and is used as the ID when secondary switcher crosspoint events are used.

•Input Crosspoints: Number of sources on the router. This should normally be left at

the default setting of 12.

•Output Crosspoints: There can only be two destinations on the 1200 series, but this

should be set to the base address + 1 (see Device Setup notes). The router will

ignore crosspoints that are lower than the base address, or higher than the base

address +1.

•Latency: The value is in frames (-999 to 999) and can be used to adjust the switcher

for frame accuracy. The default setting of 0 should normally be used.

5. Serial Port: Select the Serial Port tab. Set this to the physical serial port number on the

Device Server where the router is connected (start from the first serial card on the left;

the ports are numbered top-down). You need not use the same value as the Channel

number for the Serial Port, although it may make troubleshooting easier for you in the

future.

•Sources: Select the Sources tab and fill in descriptions (up to 8 characters) and

crosspoints for each of the source inputs. This is important if you plan on using the

router in conjunction with ADC-100 record events, which use the descriptions to

identify the source on the router. Otherwise, it is not necessary to fill in this

information (the Transmission List will not use this information for Playout events).

•Destinations: Select the Destinations tab and fill in descriptions and crosspoints for

the destinations (outputs) of the 1200, if needed.

6. System Inputs: Select the System Inputs tab and fill in the crosspoints as described

below, if desired:

•Black Input: When the Transmission List Option “Switch to Black” is selected, and

the most recent event on the list was running on a device configured to use this

router, then the crosspoint listed here (if non-zero) will be switched to the output

crosspoint used by that event if the list stops because of an error, if the event ends

and there is a Hard-Start delay until the next event begins, or if it ends normally and

there are no more events on the list. If it is set to 0 then nothing will happen.

•Colorbars: This crosspoint is used only when the Colorbars button is pressed on the

diagnostics control panel (Configuration Utility or Air Client). If it is set to 0 then the

Colorbars button will have no action.

•Station ID: When the Transmission List Option “Station ID on Skip” is selected, and

the most recent event on the list was running on a device configured to use this

router, then this crosspoint will be switched to the output crosspoint used by that

event if an operator invokes Skip on the Air Client’s control panel. When the next

event begins to play, the crosspoint is switched to whatever that event requires.

•Initial Input: This crosspoint will be switched to all outputs of the router when the

Device Server application is launched. If it is set to 0 then nothing will happen. In

most cases it is recommended to leave this function disabled (0).

•Reporting: There are three available options on the Reporting tab, depending on the

amount of information that is necessary to be logged into the ADC-100 error file when

the router is used. The actual log is configured on the Air Client application, but the

information supplied to the logging mechanism from the router driver is regulated

here.

•Errors: Enables the logging of critical failures, such as the device failing to confirm

that a transition command was executed, or when communication is lost with the

router.

•Warnings: Enables the logging of other information reported by the router. The 1200

series routers do not provide such information to automation; so enabling Warnings

will have no effect on the system.

•Crosspoint Changes: Enables the logging of each transition with a timestamp from

when it occurred.

7. The Log tab contains configurations for Manual Intervention Logging. The 1200 series

routers do not report to automation when a crosspoint change has occurred manually or

by another controller, thus changing any of the options on the Log tab will have no effect

on the system.

8. On the Backup tab, select the router that is to be used as the redundant backup router,

or leave it set to None if there is not one. The router that is configured here will receive

all of the transition commands that are sent to the main device. For this reason the

Backup router must be wired identically to the Main. There are other methods for driving

a second switcher if this limitation cannot be accommodated.

9. Cascade is an advanced configuration used for triggering additional crosspoint changes

using a single event or command from the Transmission List. For more information on

Cascade, consult the ADC-100 user manual.

10. The Wire tab configures the driver to operate in Simplex or Full Duplex mode:

•2 Wires: The driver will ignore any input from the device and never report any comm.

errors. If RS-485 operation is attempted with multiple routers (not recommended),

this option must be used and the return lines from the switcher must be

disconnected. The Device Server hardware is not capable of negotiation on an RS-

485 bus.

•4 Wires: The driver will look for confirmation from the router that a transition has

occurred, and retry (twice) if there is no reply. If there is still no reply after three tries,

the driver will stop trying and report an error (if Warnings is selected on the Reporting

tab). This is the recommended mode of operation, but only one router can be

connected to the driver.

11. Switching: There is nothing to configure on the Switching Tab; it is a diagnostic panel

that can be used to check that the router is working. Note that the Sources and

Destinations tabs must be configured prior to using this panel. There is a similar panel

available on the Air Client that does not require configuration of the Sources and

Destinations tabs; it uses the crosspoint numbers.

12. When all of the parameters are set, click OK. You will be prompted to save changes.

Operation Notes

Before the router can be used on a Transmission List, there are additional configurations required

for the List (A/V Tables). This configuration is described in the ADC-100 user guide.

Manual intervention is possible from the front panel of the 1200 series router while under

automation control, but there is no support for reporting such interventions through an as-run or

error log. If the router is to be used primarily under automation control, care should be taken

when considering the location for the control panel to minimize the risk of accidental crosspoint

changes.
