c.
Connect the RS-232 device to the 9-pin D-subminiature (DE-9) connector on the back of the
fiber
optic
remote.
Terminal assignments for the device port connectors are the same as those
shown in Figure 2-6 for the RFL 9660's rear panel PORT connectors.
You do not have to make connections to all pins. Wiring will depend on the
specific device being connected to the port. Refer to Section 16 for application
notes for the specific device you are wiring, or refer to the manual supplied with
the
device.
d.
Set TX PWR switch S2 for the required optical output power.
S2 has four possible settings, producing four different power levels:
Output
S2-1
S2-2
-16
dBm OFF
OFF
-13
dBm ON
OFF
-11
dBm OFF
ON
-10 dBm
ON
ON
When setting S2, remember that OFF is up, and ON is down.
e.
Set ADDRESS switch S1 for remote module's address.
S1 sets up a binary number that represents the port number assigned to the
device. (See Table 2-1 for the proper settings for each of the RFL 9660's 32 port
numbers). When setting S1, remember that OFF is up, and ON is down.
f.
Repeat steps 2a through 2e at all other fiber optic remotes.
2.6 SYSTEM EXPANSION
Your RFL 9660 was shipped with the correct number of device I/O modules for the number of device ports you
ordered. Up to four device I/O modules can be installed in the RFL 9660, for a maximum capacity of 32 device
ports.
When installing additional device I/O modules, the following rules apply:
1.
The bottom I/O module slot must always be occupied.
2.
Additional device I/O modules must be installed from bottom to top; do not skip any I/O module slots.
3.
An RFL 9660 may contain both RS-232 and fiber optic device I/O modules. If both types are to be
installed, the RS-232 I/O modules must be at the bottom, with the fiber optic module on the top.
4.
If you are adding an RS-232 I/O module to an RFL 9660 that already has a fiber optic I/O module, the
fiber optic I/O module must be moved up one slot and the RS-232 I/O module installed below it. If the
RFL 9660 has already been programmed for the devices connected to the fiber optic loop, it will have
to be re-programmed, since the fiber optic devices have now been moved up eight port numbers. The
address settings on the remote fiber optic modules must also be changed.
