Making Diagnostic Connections
How to Make Control System Expansion Connections between Two Routers
1 Locate the control system expansion connections on the rear of the two routers, as shown in
Figure 3-11. The connections are labeled ‘10 B 2’.
Figure 3-11. Expansion Connections to Control System (Rear View)
2 On the
primary
router (the router directly connected to the control system), connect to the ‘10 B
2’ BNC connection in either the ‘PRI CTRL’ or ‘SEC CTRL’ section using a 50
Ω
BNC con-
nector (12115898) and 10Base2 cable.
3 Connect the other end of the cable to the ‘10 B 2’ BNC connection in either the ‘PRI CTRL’ or
‘SEC CTRL’ section on the
secondary
router using a 50
Ω
BNC connector.
4 On all unused control system expansion BNC connections, install a 50
Ω
BNC terminator.
Terminating Unused Control System Expansion Connections
All unused control system expansion connections must have terminators. Unused control system
expansion connections are terminated with a 50
Ω
BNC terminator. The BNC terminator is supplied
by Miranda (part 1211598).
How to Terminate Unused Control System Expansion Connections
1 Locate the control system expansion connections on the rear of the router, as shown in Figure 3-
11. The connections are labeled ‘10 B 2’. See Figure 3-11.
2 On all unused control system expansion BNC connections, install a 50
Ω
BNC terminator
(Miranda part number 1211598).
Making Diagnostic Connections
The diagnostic connections enable the NV8256-Plus to communicate with the UniConfig applica-
tion. UniConfig is installed on a unit, separate from the router (e.g., PC), and is used to perform
system setup tasks, and configure and monitor the router. For information about using UniConfig,
see the
UniConfig User’s Guide
.
Diagnostic connections are made by connecting the router to the unit running the UniConfig appli-
cation. There are two types of diagnostic connections: temporary and permanent. A temporary
diagnostic serial connection is located on the front of each control card. Permanent diagnostic serial
connections are located on the rear of the router, labeled ‘DIAG’. For a detailed description of the
serial connections, see
on page 12.
