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.

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.

Figure 1-2: 7700PTX-CTP Example
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.

2. CARD EDGE CONTROLS
2.1. DETERMINING CURRENT IP ADDRESS SETTINGS
To read the current IP address during normal operation, press the toggle switch DOWN. The IP address
can be read on the four-character alphanumeric display.
2.2. RESTORING FACTORY DEFAULTS
To restore all settings to factory defaults, apply power to the card while holding the toggle switch UP until
the green LED is illuminated.
2.3. CARD EDGE LEDS
LED 22 is illuminated when Ethernet activity is detected.
All other card edge LEDs are for factory use only.

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.
