16.3.1 Hardware Installation and
Connections
To install the Low Speed Data (232) Module and
interface, complete the following steps.
1. Bring the FOCUS chassis “on line”.
Click on the “Online” speed button
.
This uploads to the FCS the current status,
settings, operating statistics, etc., for the
FOCUS chassis — and the 232 module.
2. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Setup
menu or click on the “Unlock FOCUS
Chassis” speed button .
This puts the chassis into a configurable state,
allowing you to install the 232 module and
interface.
3. Insert the Low Speed Data (232) Module
into the FOCUS chassis.
Carefully insert the 232 module into the top
and bottom grooves of any open slot on the
FOCUS chassis. Slide it all the way in until it
is well seated in the slot. Lock it into place
using the black ejector clip on the front of the
module.
When you first insert the 232 module, the
red/green status LED is red. If the module is
functional, the status LED turns green within
20 seconds. If the module is non-functional,
the status LED stays red, even after 20
seconds have elapsed.
4. Connect the 232 interface module to the
FOCUS chassis.
Attach the interface module to the rear of the
FOCUS chassis so that it connects to the 232
module.
5. Connect the proper wiring/connector to the
232 interface module.
Use a DB9 male connector to connect your
equipment to the interface. To properly wire

the male connector, refer to the pin assign-
ments in Figure 16-2.
The Low Speed Data (232) Module interface
board has two DB9 female connectors, as
shown in Figure 16-2. The connectors have
threaded standoffs so that you can secure the
cable you are connecting. We recommend you
