CAUTION
•Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
•Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
•Keep circuit boards in their antistatic bags when they are not in use.
•Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.
•For more complete information on electrostatic discharge safety
precautions, refer to BellcoreTM Technical Reference # TR-NWT-000870.

OPTION NUMBER FEATURES
B12-49009-00 RS-232 Current Loop Interface Subassembly
GENERAL DESCRIPTION
The 49009 Current Loop Interface Subassembly provides a bi-polar current loop or EIA Standard RS-232 data communi-
cations interface for use with the 460 Alarm and Control Sys-
tem.
CIRCUIT DESCRIPTION
The 49009-00 Current Loop Interface Subassembly functional schematic is shown in Fig. 1.
The input (RCV) to the subassembly appears at pins 2 and 4 on
connector P5. The RCV circuit uses a series of inverters which
activate when data comes in. The Data Carrier Detector (DCD)
is also activated through this circuitry. Depending upon strap-
ping, the RCV accepts bi-polar or EIA Standard RS-232 type
data signals and provides the result to the host module at the
RCV (pin 8) and DCD (pin 7) leads.
A front panel LED (RCV DATA) indicates data activity at the
RCV output.
The output (XMT) from the subassembly is picked off at pins
3 and 5 on connector P5. A gated pulse, created through a series
of integrated circuits, feeds a network that produces bi-polar
(±7 volts at 10 mA) or EIA Standard RS-232 (± 12 volts at
20 mA) signals. These outputs are dependent upon the subas-
sembly strap options selected. The host module connects to this
section of the circuit at the TXD (pin 10) and RTS (pin 12) leads.
A front panel LED (XMT DATA) indicates data activity at the
XMT output (pin P5-5).

OPERATION
There are no specific operating instructions for the 49009 Current Loop Interface Subassembly. The subassembly
starts operation when power is applied to the host module.
The front panel of the 49009 has two LEDs. The upper LED
(red) is labeled XMT and indicates that the unit is transmitting
data. The lower LED (green) is labeled RCV and indicates that
the unit is receiving data.

If it is necessary to install the subassembly on a host module,
refer to the documentation on the host module for the location of
the subassembly.
To install the subassembly, follow these steps:
1. If there is a hole plug in the front panel of the host module, remove
the plug.
2. Remove the three screws from the subassembly standoffs.
3. Place the subassembly on the board.
• Insert P4 into J4 and P5 into J5.
• Make sure each connector pin goes straight into its socket.
• Make sure the subassembly fits closely on the standoffs.
• The panel should be straight in the opening.
4. Replace the three screws in the standoffs.
