The V.11 LS utilizes an ITU V.11 (X.21) balanced interface with a maximum data rate of up
to 10Mbps. Additionally, V.11 can support data transmissions at far greater cable distances
than does RS-232. The V.11 LS can support an unlimited amount of receive only terminals
simultaneously.

SUPPORTS RS-422/449

ONE WAY DATA PATH TO TERMINALS
The V.11 LS's master port has tandem DB-15 connectors. This allows a dedicated input
port and an additional port for cascading without losing a sub-channel port. The V.11 LS
continuously broadcasts receive data, receive timing and Indicate (any user defined control
signal from the main input data source may be used). The input signals are split with the
internal circuitry and rebroadcast on the eight output ports.
The V.11 LS is housed in a sturdy aluminum enclosure and is supplied with an internal
linear power supply. The unit has a 110/220 VAC rotary select switch located on the rear of
the housing. The unit can operate on standard AC power found in all countries.
CHAPTER 1 - DESCRIPTION
1.1 FUNCTIONAL DESCRIPTION
The V.11 LS is designed for use in receive only data broadcast applications. Examples of
typical data broadcast applications are: continuously updated private or public data dis-
plays and distribution of continuous data to PCs or receive only printers. The role of VSAT
systems in receive only applications for real time data distribution is expected to increase
dramatically over the next few years. The V.11 LS is an excellent choice for applications of
this type.

CHAPTER 2 - BASIC OPERATION
2.1 OPERATION
Operation of the V.11 LS is as simple as plugging a male DB-15 cable into the female
DB-15 INPUT PORT on the back panel and plugging up to eight male DB-15 connectors
into Ports 1 - 8. Data, Clock and Indicate are received on the Master Port and are broadcast
out simultaneously on Ports 1 -8. The following table shows the pinout for the Master and
Sub-Channel Ports.
2.3 FRONT PANEL LED INDICATORS
Located on the front panel of the V.11 LS are four green LEDs. The Power indicator,
marked POWER, illuminates when AC voltage is applied to the box. Three adjacent LED
indicators illuminate in conjunction with
Receive Data (DATA), Receive Clock (CLOCK)
and the user defined control signal which is marked INDICATE. The DATA and CLOCK
LEDs will flash on and off at a constant rate regardless of the user’s clock and data rate.
The INDICATE LED will be illuminated when and if the user defined control signal is
present.

CHAPTER 3 - SETUP AND INSTALLATION
3.1 POWER CONNECTION
It is very important to check that the unit is set to the correct voltage setting for your
application before applying AC power. Located on the rear of the unit you will find a rotary
110/220 VAC switch. Using a coin or small screwdriver, gently turn the switch to the
appropriate power position as required for your installation (110 or 220 VAC).

3.2 INSTALLATION
Connect the main input data feed source into the INPUT port DB-15 female connector. The
output ports are marked PORT 1 through PORT 8. Connect from one to eight DTE V.11
(X.21) compliant devices into the sub-channels ports on the back of the V.11 LS.
3.3 CASCADING AND TERMINATION RESISTORS
If more than one V.11 LS are to receive Data, Clock and Indicate from the same source, a
shielded DB-15 one-to-one extension cable with a male DB-15 on one end and a female DB-
15 on the other end can be used to link the V.11 LS together. The box furthest from the
source of the data and clock should have jumpers JMP2, JMP3 and JMP4 moved to the
opposite position of the factory default setting for proper termination.
High quality shielded cables are recommended for box to box cascading. The cabling should
be a twisted pair with a wire mesh shield. All signal pairs should be kept together for clean
quality signals. We recommend Black Box EGM16E or equivalent cable with metal hoods.
