Operating instructions

ACCESS
The Access menus define the system partitioning, which
controls operator keyboard access to monitors, cameras,
pan/tilts, and alarms. The system partitioning is used to
segment the Switching System for the particular installation.
Keyboard numbering
Sixteen keyboards may be used with the AD2150, 12
connected to the three RS-232 ports, four connected to the 2-
wire ports.
RS-232 Keyboards
Three RS-232 ports are provided on the AD2150. These ports
may be expanded with AD1981 Port Expanders to provide 12
keyboards. For AD2150 systems with port expanders, each
RS-232 port is assigned four keyboard numbers. The keyboard
numbers, as displayed in the Keyboard Access menus, identify
the RS-232 port (1-3) and the AD1981 connector port (a-d).
If port expanders are not used, each RS-232 port uses only the
first assigned keyboard number (1a for port 1, 2a for port 2,
etc.). For proper keyboard numbering, verify if a port
expander is used and to which port it is connected.
Keyboard Numbers
Port With Expander Without Expander
Port 1 1a - 1d 1a
Port 2 2a - 2d 2a
Port 3 3a - 3d 3a
Two-Wire Keyboards
Four 2-wire keyboard ports are provided on the AD2150.
These are numbered as keyboards B2, B3, B4, and B5
respectively.
The RETURN MAIN line of the Access menu returns to the
Main Selection menu, page 4-2.
KEYBOARD/MONITOR
This Access function prevents selected keyboards from
accessing selected monitors, thereby preventing any control of
that monitor. The KEYBOARD/MONITOR menu is used to
configure the keyboards to the five monitors. The codes for
each monitor entry in the display are:
Y = keyboard has access privilege to monitor.
N = keyboard does not have access to monitor.
The Keyboard/Monitor menu entries are set default to Y, all
keyboards have access privilege to all monitors.
To change the access privilege of any keyboard:
1. Position the cursor to the monitor and keyboard entry that
is to be changed.
2. Press the ACK button. When ACK is pressed the current
setting toggles between Y = access, N = no access.
3. Repeat steps 1 and 2 for any additional changes desired.
4. Position the cursor at the PREVIOUS MENU line.
5. Press the ACK key to return to the main ACCESS Menu.
Port Expander Notes: If a port expander is used, configure
column "a", "b", "c", and "d" to access or to lock out that
particular keyboard from one of the five monitors. If a
port expander is not used, configure column "a" only.
