Revision 1.6 7700PTX-CTP - 1
1. OVERVIEW
The 7700PTX Universal Protocol Translator module provides an interface between third-party and Evertz
equipment. The 7700PTX communicates with third-party equipment either via one of four serial ports or
via a built in Ethernet port. These ports can provide bi-directional protocol support.
Function:
The function of the 7700PTX generally falls into one of 4 categories:
1. Third-Party Router Control: In this mode the 7700PTX affords VistaLINK®the ability to control
and monitor third-party routers. The 7700PTX can convey UMD information to Evertz monitoring
equipment.
2. Third-Party UMD Interface: In this mode the 7700PTX translates third-party UMD protocol data
into a format suitable for Evertz monitoring equipment.
3. Third-Party Switcher Interface: In this mode the 7700PTX extracts tally information from third-
party switchers and translates and conveys that tally information to Evertz monitoring equipment.
4. Third-Party Device Control: In this mode the 7700PTX allows VistaLINK®to control third-party
devices such as satellite controllers.
Features:
•4 serial ports RS232/422 selectable
•Modular, conveniently fits into 7700FR-C 3RU frame
•Frame status trigger
•VistaLINK®- capable for remote monitoring and control via SNMP (using VistaLINK®PRO)
The 7700PTX-CTP is a protocol translator that can accept, on any of its 4 serial ports, the Contribution
Tally Protocol.
The typical environment, as Figure 1-1 shows, has the 7700PTX-CTP connecting to a switcher. The
7700PTX-CTP, in turn, communicates with a MVP via a TCP link.
Figure 1-1: Typical 7700PTX-CTP Setup

7700 MultiFrame Manual
7700PTX-CTP Contribution Tally Protocol Translator
7700PTX-CTP - 2 Revision 1.6
The function of the 7700PTX-CTP is to monitor the Contribution Tally Protocol to:
1. Determine which, if any, of the switcher’s inputs is contributing to the switcher’s program output.
This is represented by the 7700PTX-CTP as a collection of virtual GPIs and conveyed via TCP to
the display card(s) of an MVP.
2. Determine which, if any, of the switcher’s inputs is contributing to the switcher’s preview output.
This is represented by the 7700PTX-CTP as a collection of virtual GPIs and conveyed via TCP to
the display card(s) of an MVP.
3. Determine the names of the switcher’s inputs/sources and convey them via TCP to the display
card(s) of an MVP.
As an example, suppose:
1. 12 video sources are supplied to inputs 1 – 12 of the switcher.
2. A MVP is monitoring these sources.
3. A 7700PTX-CTP communicates with the switcher via a RS-422 link.
4. The 7700PTX-CTP communicates with the display card of the MVP via TCP.
5. The MVP’s output card display matches that of Figure 1-2 where each input has associated with it
a program tally, a preview tally, and a UMD.

The names of the switcher inputs will appear on the UMD located beneath each display window. If the
input contributes to the program output the tally on the left will be active. If the input contributes to the
preview output the tally on the right will be active.

4. CONFIGURATION
4.1. CONFIGURATION STEPS
The basic steps required to configure the 7700PTX-CTP are as follows:
1. Connect a PC running a console application to the PTX debug/monitor port via the adapter cable.
2. Configure the network parameters of the 7700PTX-CTP.
3. Configure the parameters of each serial port to match those of the connected switcher.
4. Configure the CTP protocol parameters should changes to the defaults be required.
5. Configure the IP address and TCP port of the UMD peer(s).
6. Save all configuration parameters.
7. Power off the 7700PTX-CTP.
8. Physically wire the serial port(s) of the 7700PTX-CTP to the switcher.
9. Power on the 7700PTX-CTP.
4.2. DEBUG/MONITOR PORT CONNECTION
The 7700PTX-CTP is configured via the debug/monitor port, the header of which is labeled J1. A special
Evertz adapter cable allows this port to connect to the COM port of a personal computer. The following
steps describe this procedure.
1. Locate the small, keyed, four–pin end of the upgrade cable provided by Evertz.
2. Connect it to the four-pin interface (J1) near the front of the 7700PTX, directly above the card
unlock latch.

"The 7700PTX-CTP must be rebooted for any network setting changes to take effect.
4.5. SERIAL PORT SETUP
4.5.1. Parameters
The 7700PTX-CTP has 4 serial ports. The parameters associated with each serial port are listed in Table
4-2.
Parameter Special Notes
Baud Rate
Data Bits
Parity
Stop Bits
Standard For serial port 4, only RS-232 is valid.
Table 4-2: Serial Port Parameters
Typically the switcher uses 8 data bits, no parity, and 1 stop bit. The highest baud rate supported by both
the switcher and 7700PTX-CTP should be used (typically 115200).
"The serial port settings of the 7700PTX-CTP must match those of the switcher. The
7700PTX-CTP must be rebooted for any serial parameter changes to take effect.

4.6.1. VGPI Image Video Display Id
This value is used for the transport of the VGPI data. A value should be selected that does not conflict
with another display ID.
4.6.2. VGPI Refresh Count
The switcher sends tally information to the 7700PTX-CTP on a continuous and repetitive basis, even in
the absence of changes to this tally information.
Figure 4-9: Tally Info Transmission
The VGPI refresh count parameter specifies how many iterations of non-changing tally information the
7700PTX-CTP receives before it provides a VGPI refresh to the MVP. For instance, if the VGPI refresh
count is set to 750 it means the 7700PTX-CTP will receive the unchanging tally information 750 times
before it sends a VGPI refresh to the MVP. The VGPI refresh is beneficial should the MVP lose power.

4.6.3. Program Output Number
This parameter represents the output of the switcher that corresponds to the program output. The default
for this parameter is 5.
4.6.4. Program VGPI Offset
This is the value added to the switcher’s source number to obtain the program VGPI number that the
7700PTX-CTP transmits to the PPV(s). Table 4-5 shows the default offset (0) as well as a user-defined
offset (1). Selecting an offset of –1 will disable the transmission of the program VGPIs.

VGPIs.
4.6.5. Tx Program UMD
Suppose the switcher’s program output is being monitored by a display window of the MVP.
Figure 4-11: Program UMD
The display window can have a UMD associated with it. When the Tx Program UMD parameter is set to
yes, the 7700PTX-CTP will transmit the name(s) of the switcher source(s) contributing to the program
output.
4.6.6. Program UMD Display Id
This parameter should match the protocol ID of the UMD displaying the names of switcher source(s)
contributing to the program output. For the example of Figure 4-11, the program UMD display ID would be
set to 175.
4.6.7. Preview Output Number
This parameter is the output of the switcher that corresponds to the preview output. The default for this
parameter is 6.
