SYSTEM BASICS
This example screen shows the settings for a site with 10 cameras,
2 keyboards and a single alarm card with 16 alarm inputs.
Maximum Camera number
:
This value is used to specify how many cameras are connected to
the Tx1500 and prevent displaying blank screens when attempting
to display non-existent cameras.
Maximum Monitor number
:
This value is fixed at 8.
Maximum Alarm number
:
How many alarm inputs are connected to the Tx1500. This value
should be 0 unless optional TX1500/AL16 alarm card/(s) are used.
Each alarm card has 16 alarm inputs therefore if 4 cards are used the maximum alarm number must be set to
64. The following table shows the maximum alarm numbers that should be used.

Number of Keyboards
:
It is possible to have four control points for the Tx1500. Each control point can be either a Tx1500 keyboard,
Touch Screen T-Command keyboard or RS232 control from a PC or 3
rd
party controller using a TX1500/BBUS -
IF.
The Number of Keyboard value must be set to the correct number of control points. The default value is 1. Any
additional keyboards or B-BUS interfaces will not function if this value is not correct. If the value is too high
sluggish control will result as the Tx1500 waits for a response from the none -existent keyboards etc.
System Pacing Factor
:
This value is used to add delays between RS485 telemetry commands. For the majority of installations the value
should be 0. It is provided to allow RS485 control of 3
rd
party dome cameras and telemetry receivers that require
a delay between commands. If using exclusively up-the-coax telemetry then this figure must always be set to 0.
Text on Monitors
:
Monitor outputs 1 – 4 as previsously described have the ability to display the camera number, monitor number
and other messages. Text on these monitors can be disabled by using the + or – key to cycle through options.
As an example this feature would be useful if the monitor output is used as a public display monitor in a retail
installation.
System Type
:
Sets the CCTV video standard as either PAL or NTSC. Use the +/ - keys to select the standard which is
appropriate. This is normaly PAL in the UK.
Return
:
Displays the TX1500 Main Menu again.
