SMS7000 EC9535 Router

command

status

command

status

The EC9535 GSC Node Bus Converter is a communications protocol converter that allows
Miranda’s NV8288, NV8288-Plus and NV8500 family routers to communicate with an SMS7000
router control system.

A router must have (1) a GSC Node Bus connector and (2) a control card that follows the
SMS7000 protocol. The NV8288, NV8288-Plus and the NV8500 family routers do not have these
items.

The EC9535 has the GSC Node Bus connector and the control cards that follow the SMS7000
protocol. The SMS7000 connects to the EC9535, which in turn, connects to the router:

The EC9535 interprets commands from the SM7000, sending equivalent commands to the
router. It also interprets status mesages from the router, returning their equivalent to the
SMS7000.

Product Overview

The EC9535 GSC Node Bus Converter is used as an interface between a SMS7000 system
controller and a specific Grass Valley router. Unlike a router, the EC9535 does not actively
manage signals. Instead the EC9535 provides a GSC Node Bus to serial interface that enables a
SMS7000 system controller to communicate wit h Miranda routers that feature only serial
system controller connections. In addition, the EC9535 provides high reliability through redun­dant power supplies and redundant control cards, as well as deterministic communications
processing.

Mounting

The EC9535 GSC Node Bus Converter mounts in a rack with minimum dimensions of 2RU high
(3.47 inches, 88.1mm), and 16.0 inches (406 mm) deep. When placing the rack in your facility, be
sure to leave enough space for air flow through the front and rear of the EC9535 and within easy
access of an AC power source. For mounting instructions, see Rack Mount

Fuses

The EC9535 GSC Node Bus Converter has no user-serviceable fuses.

Introduction

EC9535

GSC Node Bus Converter

Frame Front

Cooling

The EC9535 GSC Node Bus Converter has one fan providing forced air cooling. The fan is
accessed from the front of the frame. The fan draws cooling air from the front of the frame,
through the door, and exhausts it through a grill in the rear door. The EC9535 must have the
door correctly installed and closed for proper airflow through the chassis.

Power Supply

Power for the EC9535 is supplied through the Grass Valley PS0007 power supply module. The
PS0007 power supply module accepts a wide range of AC input voltages and produces +48 VDC
outputs. The power supply automatically senses the AC input voltage range (90–130 and 180–
250 VAC) and adjusts to maintain a relatively constant DC output; no voltage selection is
required.

Frame Front

If airflow is impeded, overheating may occur.

The front of the EC9535 GSC Node Bus Converter features a single door. When facing the front of
the frame the right-hand side features an open grill through which a fan draws cooling air. A
handle is provided on the left-hand side. The door is hinged on the right-hand side and swings
open from left to right. By opening the door, you can access the control cards.

Figure 1-1 shows the front of the EC9535 with the door closed. Figure 1-1 shows the EC9535
with the door removed. The card guides that house the control cards are visible.

Control Cards

The EC9535 has two control cards (EM0374), one primary and one secondary. The secondary
card is optional and used as a redundant, or stand-by, controller. Each control card is equipped
with a special mezzanine (SM0220) that facilitates communication between the control cards
and the SMS7000 system controller. Each card receives commands from a router control system,

and in turn, sends commands to the connected router’s control cards. Only the active control

card sends commands. The active control card updates the stand-by control card.

Both the primary control card and the secondary control card receive commands from the
router control system, but only the active control card responds. Because both cards receive
router control system commands, if the active control card fails, the stand-by control card auto­matically takes over processing without interruption. In addition, the primary control card and
secondary control card communicate with each other. Should either control card fail, the newly
active control card communicates the failure to the router control system.

Four LEDs on the front of the control card indicate the card’s status: low battery (red), alarm
(red), active (amber), and operating normally (green). For more information, see Indicator LEDs
on page 21.

Rear Connections

The rear of the EC9535 frame features a back plate containing several connections for managing
system functions and two power connections:

EC9535

Reference Manual

Fig. 1-3: EC9535 (Rear View)

These connections enable you to connect to a system controller, reference signals, power
sources and system alarms. When facing the rear of the frame, the far right-hand side has a grill
behind which is located the fan for frame cooling. All system and power connections are located
to the left of the fan.

GSC Node Bus Control Connections

The EC9535 GSC Node Bus Converter has one port labeled ‘GSC NODE BUS’, as shown in
Figure 1-4. This connection is used to connect a SMS7000 system controller to the EC9535. In
turn, the EC9535 is connected to a NV8288, NV8288-Plus or NV8500 Family router. Through the
GSC Node Bus connection, the SMS7000 router control system sends commands to both the
EC9535’s primary and secondary control cards. In turn, the control cards forward the commands

Serial Control Connections

Figure 1-5 shows the serial control connections to the router. The ports are divided into two sets,
one primary control and one secondary control. Primary control is the connection to a router’s
primary control card. Secondary control is the connection to a router’s secondary control card
(which is optional for redundancy). Each set is further divided into connections that correspond
to router control systems: ‘CTRL 1’ corresponds to the primary control system and ‘CTRL 2’ corre­sponds to an alternate control system. Only ‘CTRL 1’ is used. ‘CTRL 2’ is not used because there is
no alternate control system (i.e., backup system) for the SMS7000 system controller. However,
the connection is provided for future flexibility. For installation instructions, see Making Router

Connections on page 12.

Diagnostic Connections

The diagnostic connections enable the EC9535 to communicate with the UniConfig application.
UniConfig runs on a PC separate from the EC9535 and is used to perform system setup tasks,
and configure and monitor EC9535. (See Configuration

Diagnostic connections connect the EC9535 to the computer (PC) running the UniConfig appli­cation. Two diagnostic connections are located on the rear of the EC9535, labeled ‘DIAG’. The
ports are divided into two sets: one primary and one secondary, as shown in Figure 1-6 on page

5. The primary control connects to EC9535’s primary control card. The secondary control

Ethernet Connections

The EC9535 has two Ethernet ports, labeled ‘10/100BT’, as shown in Figure 1-7. These ports are
divided into two sets, one primary (‘PRI CTRL’) and one secondary (‘SEC CTRL’). These connec­tions can be used to connect to a PC running UniConfig. However, in general these connections
are not used at this time and provided for future network use.

Fig. 1-7: Ethernet Control Connections (Rear View)

In order for EC9535 to communicate with UniConfig through an Ethernet connection, you must
configure an IP address for each of EC9535’s control cards. The IP address is set using UniConfig.
However, UniConfig runs on a PC and cannot communicate with EC9535 until an IP address has
been entered. Therefore, you must use a serial connection

— the ‘DIAG’ port(s) — to communi-

cate with the computer (PC) running UniConfig to define the IP address(es). See Making

Diagnostic Connections on page 13.

If using an Ethernet connection, 50ohm terminators must be installed on the ‘10 B 2’
connectors.

AES Reference Connections

The AES reference is used for clock generation, which provides a timing reference for AES
synchronous signals and for timing circuits on the EC9535 control card. This reference is not

Video Reference

The EC9535 provides timing reference connections for video signals, labeled ‘VIDEO REF 1’ and
‘VIDEO REF 2’, as shown in Figure 1-9. Located on the rear of the frame, these connections
provide a reference input for determining the video frame switch point. The video reference
connections require a stable source of PAL, NTSC or Tri-level sync. This reference is not currently
used, but provided for future flexibility. For more information, contact Technical Support. (See

Grass Valley Technical Support

on page 35.)
