Page 8: Introduction
Sprint 2 Time-Division Multiplexer Introduction The Sprint 2 is a four or eight channel time division multiplexer offering users voice and data integration over digital links up to 64Kbps. Both local and remote units may be easily configured from one end of the link, using a terminal or PC terminal emulation software. -
Page 9: V.24 Low Speed Data Only
Sprint 2 Time-Division Multiplexer The Sprint 2 can be used in many applications, from simple asynchronous V.24 data transfer through to a complicated mix of low speed V.24 and high speed V.11 data with up to two voice channels. The low price of the basic unit and options give users the opportunity to maximise the benefits of their networking budget. - Page 10 Sprint 2 Time-Division Multiplexer This high speed X.21/V.11 port could also be used to split bandwidth between some low speed peripherals and a Remote LAN Bridge such as is shown in this diagram below.

Page 11: Technical Features
Technical Features Sprint 2 Throughput/Efficiency Data throughput may be easily calculated. The overhead for composite rates above 32.8Kbps is 1600bps. For rates below 32.8Kbps, the overhead is halved. For example, a composite rate of 28.8Kbps will yield a throughput of 28Kbps. Link Rate (Kbps) Efficiency (%) Throughput (Kbps) -

Page 14: Use And Configuration
Use And Configuration This section covers connection and set-up of the channel data ports. The composite port is covered in the Installation section of this manual. Data Channel Connection Low speed peripherals are connected to the V.24/V.28 (and X.21/V.11 where the High Speed Data option is fitted) DB25 connectors configured DCE and numbered 1 to 8 at the rear of the multiplexer. -
Page 15: Supervisor Terminal Emulations
Supervisor Terminal Emulations Several terminal emulations are supported by the Sprint 2. When connection is made between the terminal or PC and the rear panel port labelled SUPERVISOR, the following screen will appear: Please select terminal type from the following: 1 = VT52/HP2600 2 = ANSI/VT100/VT200 3 = ADDS... -
Page 16: General Keyboard Conventions
There are two main areas on the supervisor set-up screen used to change parameters for the Sprint 2. Upper left - System parameters (Mode, Link Clock, Carrier, Residual, and Configure). Bottom - Channel configuration. General Keyboard Conventions Only a few keys are required to configure the Sprint 2 multiplexer. They are summarised as follows. -
Page 17: Changing Parameters

Supply Voltage & Connection 100 - 240V AC without adjustment. Optional DC 48V DC without adjustment. The Sprint 2 may be optionally DC or AC powered. The AC power supply is a switched mode unit, whereas the optional DC power supply unit is a DC to DC convertor. -
Page 26: Composite Interface Selection
Composite Interface Selection Interface cards are used to determine the interface type (X.21/V.11, V.24, V.35 etc.) of the composite link. It is necessary to use the corresponding external cable to make connection once the interface card has been fitted. It is necessary to set link positions on the composite interface cards as follows: Interface Link Number DTE Setting... -
Page 27: Troubleshooting
Troubleshooting Front Panel LEDs During normal operation only the CARRIER front panel LED should be constantly illuminated. The DATA LEDs will flash as appropriate when data is transmitted. LED LABEL CONDITION NOTES CARRIER Even Flash No communication with remote unit - link or multiplexer fault. -
Page 28: Diagnostics & Loopbacks
Diagnostics & Loopbacks A number of diagnostic configuration options are available. It is possible to loop back the data channels and the composite link, both locally and remotely, to test for correct operation. The configuration procedure is detailed in the Use and Configuration section starting on page LOCAL COMPOSITE LOOPBACK loops back the composite link of the local multiplexer, i.e. -
Page 29: Back-To-Back Testing
The display does not proceed to the display of VDU emulations. The front panel LED display also stops. This indicates a fault that cannot be remedied. Please contact Black Box for assistance. Back-To-Back Testing It is possible to test a pair of multiplexers in a back-to-back mode. This is a useful way to gain familiarity with the configuration procedures, and to check for correct operation if malfunction is suspected. -

Page 35: Appendix C - Emc Requirements
This product relies on the use of screened cables for connection to the 15 way and 25 way DB ports. The cables must have the foil or braid screen connected effectively to the metal headshell to ensure continued compliance. These headshells are available from Black Box under the following part numbers:... - Page 36 It is in the user's interest to ensure continued product immunity against mains born transients, and static discharge. To achieve this, it is important to ensure that equipment is effectively earthed. The mains IEC cable provides some protection, but to achieve optimal immunity, the chassis EARTH screw connection should be connected to a local EARTH busbar or cabinet frame wherever possible as shown above.
