Operation
Category Selection
Category Selection
Your panel has 10 fixed category buttons and perhaps other optional category buttons. The
fixed category buttons are arranged, like a telephone keypad, among the right-hand set of
function buttons:
Every category button can represent up to three items: a source category, a destination
category, and a suffix. By pressing category buttons in succession, you can construct a
device name.
A category button selects a source category immediately after you place the panel in
source mode by pressing a ‘Source Mode’ button (or a ‘Src/Dst Mode’ button).
A category button selects a destination category immediately after you place the panel in
destination mode by pressing a ‘Destination Mode’ button (or a ‘Src/Dst Mode’ button).
After you select a category, the category name appears as the first part of a device name
you are building. The category buttons you press subsequently select suffixes which are
appended to the device name you have built so far. As you continue to append suffixes, the
category buttons that no longer apply to the name you are building become disabled. In
fact, at some point all the category buttons might become disabled.
Suffixes may be numeric or alphanumeric, and up to 4 characters in length. Any device may
have up to 8 suffixes. However, device mnemonics are limited to 8 characters. Therefore, the
usual
— and default — suffixes are just the numerals 0 –9.
Example: you want to select the source device
CAM_12
.
1 Press ‘Source Mode’ or ‘Src/Dst’ (if the panel is not already in source mode).
2 Press the category button that selects category
CAM
. The display shows
CAM_____
.
3 Press the category button for suffix 1. The display shows
CAM__1
or a similar name.
4 Press the category button for suffix 2. The display now shows
CAM_12
.
At this point, you could press a ‘Clear’ button — as you would a backspace key — to
erase the most recent entries in the name. If you press ‘Clear’ once, it would erase the
“2” you just entered.
5 The desired source is selected.
Category Buttons for Rapid MD Device Selection
Category buttons (that are numeric suffix buttons) also allow you to enter a page number
for multi-destination devices. This is a convenience, but it is available only in MD mode
when no category device selection is in progress.
For example, if you have 512 MD devices, there would be 64 pages of MD devices. In MD
mode, if you press category suffix buttons “3” and then “4” (if your panel has them), the
display immediately jumps to page 34 of the MD devices. This shortcut saves you the
trouble of pressing ‘Page Up’ or ‘Page Down’ to scroll through the device pages.
