Operation

In use, the X50 modules should be transparent - the system and its peripherals

should operate exactly as normal, the only difference being that they are now up

to 50 metres apart.

In some installations, you may see some 'shadows' to the right of high contrast

screen characters. This can be caused by an incorrectly selected sharpness setting

and it may be necessary to make adjustments to correct this. Please see

sharpness adjustment

in the 'Installation' section.

When using two sets of X50 modules to allow two users to access a single

computer, be aware that arbitration between the users is handled by the USB

sub-system of the computer. Unlike with other Adder products, this means that

both users can control the computer at exactly the same time and the resulting

keyboard and mouse influences will be an amalgam of the two inputs - i.e. a

mouse move to the right by one user will cancel out a simultaneous left mouse

move by the other. The same is also true when the local module has feed-

through peripherals attached to it, adjacent to the computer.

For this reason, the X50 dual user arrangement is better suited to situations

where two users would not often require simultaneous access.

USB

Each X50 remote module provides four USB outlets, each of which can support

USB 2.0 peripherals at speeds up to 12Mbps. The X50 appears to the computer

as a four port USB hub.

If the link between the modules is interrupted, any connected USB peripherals

Video

will be automatically disabled and re-enabled once the connection is restored.

[MS2 variant only] Note: When connecting four USB devices to the unit, ensure

that their total power requirements do not exceed 1700mA (1.7A). The USB

standard states a maximum allowable current draw of 500mA (0.5A) per device,

although most devices remain well below this limit - USB keyboards and mice

typically require 100mA. Each X50 contains a self-resetting fuse that will prevent

damage by shutting down the unit if the total power draw becomes excessive.

RS232 serial

The MS2 variant modules provide additional support for an RS232 device. The 9

way male D-type socket on the remote module supports speeds up to 115,200

baud and all PC-AT flow control pins are supported.
