Introduction
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 redun-
dant 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 on page 10.
Fuses
The EC9535 GSC Node Bus Converter has no user-serviceable fuses.

Introduction
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
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.
Fig. 1-1: Front of EC9535 with Door Closed
Fig. 1-2: Front of EC9535 with Door Removed
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,
If airflow is impeded, overheating may occur.

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 auto-
matically 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:
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

to the attached router through serial connections. (See Serial Control Connections on page 4.)
For installation instructions, see Making System Controller Connections on page 11.
Fig. 1-4: GSC Node Bus Control Connection (Rear View)
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’ corre-
sponds 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.
Fig. 1-5: Serial Control Connections (Rear View)
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 on page 19.) See also the UniConfig
User’s Guide.
Diagnostic connections connect the EC9535 to the computer (PC) running the UniConfig appli-
cation. 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 connec-
tions 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.
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

Installation
When setting up an EC9535 GSC Node Bus Converter for the first time, or reconfiguring an
existing configuration, there are certain steps that must be performed. It is recommended that
initial installation and later reconfiguration tasks be performed in a specific order to avoid
possible complications.
Perform installation and reconfiguration tasks in the following order. If you are reconfiguring,
only perform the step related to the configuration you are changing:
1 Mount the EC9535 in a rack. See Rack Mount on page 10.
2 Make connections between the EC9535 and the SMS7000 system controller. See Making Sys-
tem Controller Connections on page 11.
3 Make connections between the EC9535 and the router. See Making Router Connections on
page 12.
4 Make diagnostic connections. Diagnostic connections enable the router and UniConfig to
communicate. This is important when initially configuring the router and any time the router
is reconfigured. See Making Diagnostic Connections on page 13.
5 Connect the alarm connection on the router to an external indicator. See Making System
Alarm Connections on page 15.
6 Connect power. See Connecting to Power on page 16.
7 Install UniConfig. If reconfiguring, UniConfig does not need to be reinstalled. See the Uni-
Config User’s Guide.

Preparing for Installation
Preparing for Installation
You will need the following items before getting started:
Rack Mount
The EC9535 is designed to mount in a 19″(482.6mm) EIA rack.
How to Rack Mount the EC9535
1 Determine the placement of the EC9535 and the rack in the facility. When placing the frame
and rack, be sure to locate the rack near an accessible AC source power outlet. The AC source
is used to power the frame.
2 Lift the frame into position and attach it to the front of the rack with the appropriate screws.
Be sure to place screws in all frame mounting screw holes.
3 If open, close the front door. This ensures proper airflow for frame cooling.
Installing Control Cards
The EC9535 comes with two control cards (EM0374) already installed. Each control card has a
mezzanine (SM0220) designed to communicate with the SMS7000 control system. The
following are instructions for installing control cards, should the need arise.
Cards are inserted by sliding them into card guides through the front of the frame.
A PC running Windows®2000 or higher, or Windows XP Professional.®This PC is
required for system configuration.
PC hardware requirements:
CD drive.
EIA-232 serial COM port (DE9) capable of operating at 38.4kbps.
10BaseT or 10/100BaseT (preferred) Ethernet port.
Ethernet cables (category 5) with RJ-45 connectors. (optional)
EIA-232 serial cable with DE9 connectors, wired straight-through, male to female.
75ΩBNC connector and coaxial cable.
Frame rack suitable for mounting EC9535.

How to install control cards
1 Open the door at the front of the frame. The door is hinged on the right-hand side and
swings from left to right. Use the handle on the left-hand side to gently pull the door open.
2 There are two control card guides, as shown in Figure 2-1. Insert each control card horizon-
tally into each set of guides. The cards should slide in easily; do not force them.
Fig. 2-1: Front of EC9535 with Door Removed
3 For each card, press the lever(s) inward, making sure each card is fully seated in its slot.
4 Close the frame door. The door must be closed for the router cooling system to work prop-
erly.
Making System Controller Connections
In order for a SMS7000 system controller and a NV8288, NV8288-Plus or NV8500 Family router to
communicate, the system controller must be connected to an EC9535. The SMS7000 system
controller is connected using the ‘GSC NODE BUS’ connection located on the rear of the EC9535
frame. The connection uses a 75ΩBNC connector and coaxial cable.
How to Make SMS7000 System Controller Connections
1 Locate the GSC Node Bus connections on the rear of the router, as shown in Figure 2-2. Sys-
tem controller connections are labeled ‘GSC NODE BUS’.
Fig. 2-2: GSC Node Bus Control Connection (Rear View)
2 Connect to the ‘GSC NODE BUS’ connection using a 75 ΩBNC connector and coaxial cable.
Do not drop, roughly handle, or stack circuit boards. If you cannot easily insert or remove a
board, stop and contact Grass Valley Technical Support.

tions, refer to the SMS7000 documentation.
4 On the unused GSC Node Bus connection, terminate the loop-through by installing a 75Ω
BNC terminator.
Making Router Connections
In order for a NV8288, NV8288-Plus or NV8500 Family router to communicate with a SMS7000
system controller, the router must be connected to an EC9535. The router is connected using
the serial control system connections, located on the rear of the EC9535, and a cable provided
by Miranda (WC0152). The proprietary cable is 20 feet (6.096 meters) long with two DE9 (a.k.a.
DB9) connectors on each end for a total of four DE9 connectors.
The serial control ports are divided into two sets that enable the primary control card or the
secondary control card in the EC9535 frame to communicate with the corresponding control
card in the router frame.
How to Make Router Control Connections
1 Locate the serial control connections on the rear of the router, as shown in Figure 2-3. Serial
control connections are labeled ‘PRIMARY CONTROL’ for the primary control card and ‘SEC-
ONDARY CONTROL’ for the secondary control card.
Fig. 2-3: Serial Control Connections (Rear View)
2 Locate the cable WC0152 provided with the EC9535. The cable has four DE9 connectors as
shown:
