Frequently Asked Questions - TL158AE-R3 Black Box

How do I set the DTE/DCE jumper for each port?

Refer to the rear panel jumpers. If connecting to a modem, multiplexor, or computer terminal/printer port, select DTE (data on pin 2, input on pin 3). If connecting to a COM port, terminal, or printer, select DCE (data on pin 3, input on pin 2).

How many slave devices can I connect?

You can connect up to eight slave devices to channels 1 through 8.

What is the maximum cable length for connections?

Typical cable length should not exceed 50 feet (15.2 m). For longer distances, use extended-distance cable.

What should I do if no indicator lights are on?

Check that the wall outlet is powered and the wall-mount transformer is firmly plugged in. If still off, the unit may be defective and should be returned for repair.

What does the COMP LED indicate?

The COMP LED lights up whenever a 'SPACE' (binary 0) is detected on the composite input signal.

Can the DB25 Data Broadcast be rackmounted?

Yes, an optional rackmount kit (part number TL486) is available.

What are the pin assignments on the DB25 connectors?

Pin 2 (TXD) and pin 3 (RXD) are used for data, pin 7 (SG) for signal ground. Pins 4 (RTS), 5 (CTS), 6 (DSR), 8 (CD), and 20 (DTR) are looped back. See manual for diagram.

How can I test if the unit is working?

Connect a terminal to the composite port and a loopback connector to each slave channel. Set terminal to full-duplex mode. Type letters; if they appear on screen, the unit is working.

What does the MTBF rating mean?

MTBF stands for Mean Time Between Failures, estimated at 250,000 hours under ground benign conditions. It indicates reliability.

Is this device suitable for residential use?

This device is a Class A computing device. It is designed for commercial environments. In residential areas it may cause interference requiring corrective measures at the user's expense.

2. Introduction

The DB25 Data Broadcast receives an asynchronous signal and redistributes it to up to eight slave devices. It can be used, for example, to distribute a signal from a computer to eight different terminals. The DB25 Data Broadcast takes the signal appearing at the composite connector (COMP), regenerates it, and distributes it to eight slave connectors (CH 1–8).

3. Installation

The shipping container should include this manual, the DB25 Data Broadcast, and the wall-mount transformer.

An optional rackmount kit (part number TL486) is available.

To install the DB25 Data Broadcast:

1. Remove power from the terminal or computer that will be connected to the DB25 Data Broadcast unit.
2. Connect the composite connector (labeled “COMP”) on the rear of the DB25 Data Broadcast to the source of data (usually a modem, multiplexor, or computer port). The length of this cable should not exceed 50 feet (15.2 m) in most applications without using extended-distance cable. Set the DTE/DCE jumper as appropriate.

NOTE

If connecting to a modem, multiplexor, or terminal/printer port on a computer, select DTE. The connector will output data on pin 2 and input data on pin 3.

If connecting to the COM port, terminal, or printer, select DCE. The connector will output data on pin 3 and input data on pin 2.

1. Connect up to eight slave devices (usually terminals or printers) to the channel connectors of the DB25 Data Broadcast. The length of these cables should not exceed 50 feet (15.2 m) in most applications without using extended-distance cable. Set the DCE/DTE jumper for each port as appropriate. (See the Note above.)
2. Plug the wall-mount transformer into a wall socket. The red PWR (power) light should be ON.
3. Apply power to the master and slave devices.
4. The DB25 Data Broadcast is now ready for operation.

4. Functional Description

The DB25 Data Broadcast unit supports three leads on each port connector: Transmit Data (TXD), Receive Data (RXD), and Signal Ground (SG). The input to the composite “COMP” port is regenerated and simultaneously sent out on the output lead of each of the eight slave ports, channels 1 through 8.

The input into each of the slave ports is regenerated, ORed together, and assembled to produce the output signal which is transmitted from the composite port. The signals grounds for all of the ports are tied together.

RTS, CTS, DTR, DSR, and CD are also supported and looped back as shown in the following pin diagram.

Figure 1. Pin Designations for the DB25 Connectors.

The front-panel indicators show the presence of primary power when the red PWR light is on. The state of the composite input signal is indicated by the COMP LED lighting whenever a “SPACE” is detected. The state of each slave port’s input signal is indicated by the CH 1–2 LED lighting whenever a “SPACE” is detected.

5. Troubleshooting

The most effective way to troubleshoot a system using the DB25 Data Broadcast is to bypass the DB25 Data Broadcast completely and connect one of the slave devices (such as a terminal) directly to the source equipment (computer port, modem, or concentrator). If the problem is corrected with the Data Concentrator out of the circuit, inspect the unit closely for loose connections. If the unit is defective, return it for repair.

A loopback connector and an asynchronous terminal (or a PC with a terminal-emulation program) may also be used to check the DB25 Data Broadcast. Connect the terminal to the composite channel and connect the loopback connector, in turn, to each of the slave channels. Set the terminal to full-duplex mode. Then type a few letters. If you see those letters on the terminal screen, the DB25 Data Broadcast is working.
