INS147-2 UDL-Modem Installation Manual

1. Regulatory Requirements

The UDL-Modem unit must be installed by an electrically competent person.

Before attempting to install the UDL-Modem unit, the installer must be aware of

the regulatory requirements detailed in this section.

Application

The UDL-Modem is suitable for connection to the following types of telephone

line:

•Direct exchange lines (PSTN).

•PABX exchanges (with or without secondary proceed indication).

Approval

The UDL-Modem is classified as a Stand Alone Modem Apparatus and has been

approved for connection to analogue PSTN in the UK for the following usage:

•Host Independent Modem (Answer Only Operation)

•Serial Connection

•Hard-wired connection to the network

Any other usage will invalidate any approval given to the apparatus, and as a

result the apparatus ceases to comply with the standards against which the

approval was granted. The standards against which the approval was granted

are as follows:

•TBR 21

•EN 41003

•EN 60950

The apparatus is marked in accordance with the Telecommunications Apparatus

Marking and Labelling order 1985 (SI 1995 / 717).

APPROVED for connection to telecommunication

systems specified in the instructions for use

subject to the conditions set out in them

650074

Texecom

Remote UDL Com REN=1 BABT

REN Rating

As a guide to the number of apparatus that can be simultaneously connected to

an exclusive line, the sum of the REN values must not exceed 4. A BT telephone

is assumed to have a REN = 1 unless otherwise marked.

The UDL-Modem has REN = 1.

2. Overview

General

The UDL-Modem consists of a single PCB enclosed in a small plastic case. It is

compatible with the following Control Panels:

•Veritas R8 Plus

•Veritas Excel

•Veritas Digitas XL

The unit is connected to the Control Panel via a 4-wire harness (supplied) and

can be mounted inside the Control Panel. Connections are provided to connect

the UDL-Modem to the Public Switched Telephone Network (PSTN).

In order to use the UDL-Modem you will require a PC with Windows 95, 98 or NT

and an analogue modem that supports V.21, V.22 or V.22bis operation.

To obtain your FREE copy of the FastCom Programmer Software and Veritas

upload/download (Veritas UDL) software please complete and return the

Software Registration form enclosed with the UDL-Modem.

UDL

Telephone Network

The UDL-Modem can accept serially connected telephone apparatus. When the

UDL-Modem is online it will temporarily disconnect all serially connected

telephone apparatus (e.g. phones, answer-phone, etc.) so that they do not

interfere with data transmission. This means that the UDL-Modem does not have

to be connected to a dedicated telephone line.

Operation

In its normal mode of operation the UDL-Modem will monitor the telephone line

for an incoming ringing signal. The LED flashes once every second when the

unit is in this mode. Once the ringing signal is detected the following sequence

of events occur.

•The UDL-Modem will pick up the telephone line, and establish a

connection with the remote modem. If a connection is established the

LED will flash at a faster rate.

•Once the connection is established the remote user may upload data

from the control panel or download data from a PC.

•Once the remote user has finished, the remote modem will go offline

forcing the UDL-Modem to hang up and return to its normal mode.

UDL-Modem Installation Manual INS147-2

3. Installation

Connection Status

Connection terminals on the UDL-Modem are described as either "Safety Extra-

Low Voltage" circuits (SELV) or "Telecommunications Network Voltage" circuits

(TNV).

The PCB layout and table below shows the two types of circuits.

•It is important that the installer ensures that TNV connections are only

connected to the PSTN, and SELV circuits are only connected to other

circuits designated as SELV circuits.

•Interconnection circuits should be such that the equipment continues to

comply with the requirements of 4.2 of EN 41003 for TNV circuits and 2.3

of EN 60950 for SELV circuits, after making connections between circuits.

Mounting the UDL-Modem

%To install the UDL-Modem Proceed as follows:

1) Isolate ALL power from the control panel (battery and mains). Do not

attempt to continue if the mains or battery supply is still present.

2) Remove the two cover screws from the UDL-Modem and unclip the

two halves of the case.

3) Plug one end of the 4-wire harness onto J1 and the other end onto the

control panel connector (PL1 – PC-LINK). Ensuring that the harness

enters through the cable entry knockout “A” (see Figure 2) in the base.

4) Ensure that the Answer Phone Deferred link “J2” is set for the

appropriate setting, see Figure 1.

5) Secure the UDL-Modem to the control panel base using the self-

adhesive pads.

Connecting the UDL-Modem to the Telephone Line

%To connect the telephone line, proceed as follows:

1) Connection to the telephone network must be made via an NTE5

master socket (Line Box).

2) Using the cable type 1/0.5mm CW1308, strip back 5mm of the

required cores and feed through cable entry “B”.

3) CW1308 cable is available from RS Components (Part No. 368-413).

Alarm or any other type of cable must not be used.

4) Connect the cores to the terminal blocks marked “A”, “B”, “A1" and

“B1”.

5) Remove the two screws from the BT master socket and remove the

bottom section from the master socket.

INS147-2 UDL-Modem Installation Manual

6) Connect the cable from the UDL-Modem to the BT master socket

terminals.

7) A special insertion tool will be required to connect the cable to the

master socket, this is available from RS Components (Part No. 470-

487).

8) Replace the bottom section of the master socket and re-secure the two

screws.

Note 1:

Note 1:Note 1:

Note 1: All apparatus that require access to emergency services (999 & 112)

must be connected to the master socket. Devices that do not require access to

the emergency services such as faxes, modems and answer machines etc can

be connected to the extension sockets (see Note 2 below).

Note 2:

Note 2:Note 2:

Note 2: Devices that are connected to the extension sockets will be isolated

from the telephone line whilst the UDL-Modem is active and therefore access to

the line (including emergency services) during this period is inhibited.

Testing

%Once all the installation steps have been completed, proceed as follows:

1) Connect power to the control panel.

2) Observe that the LED on the UDL-Modem flashes once a second.

3) Ask the operator of the Veritas UDL Software to establish a connection

and observe that the LED flashes at a faster rate when the connection

is established.

UDL-Modem Installation Manual INS147-2

4) Ask the operator of the Veritas UDL Software to perform an upload

from the control panel.

5) Once the upload is completed ask the operator of the Veritas UDL

Software to hang-up and observe that LED returns to its flashing

mode.

6) Secure the cover of the UDL-Modem using the two screws supplied.

7) Finally replace and secure the cover on the control panel.

Clearing the NVM Security Password

The Veritas UDL Software has the option to send a password, which is stored in

the UDL-Modem’s NVM. Once the password is set any future communication

attempts from the PC will only be accepted if the password in the PC matches

the password stored in the UDL-Modem. The password for the Veritas UDL

Software is configured in the modem setup screen, see the on line help for

further details.

%To clear the NVM password proceed as follows:

1) Remove power from the UDL-Modem by unplugging the 4-wire

harness.

2) Fit jumper link across J2 (Answer Phone Deferred).

3) Re-apply the power to the UDL-Modem by plugging the 4-wire harness

back on.

4) Within 5 seconds remove jumper link J2, the LED will flash on and off

three times to indicate that the NVM has been cleared.

5) Re-fit jumper link to J2 if Answer Phone Deferred is required.
