The ARP-32 Audio Routing Panel is used to establish audio paths by forcing crosspoints. The ARP-32 connects to J3 of the XCP-ADAM-MC break-out panel, along with other PAPs, LCP-102s, and UIO-256 devices.
The keys on the left-hand side of the ARP-32 are programmed with input ports; those on the right-hand side are programmed with output ports. If the intercom is configured to have separate input and output alphas, then input alphas are shown for those keys on the left side of the panel, and output alphas for those on the right.
By pressing a single key, the user can view what audio paths are forced to (or from) a particular port, and can also view any crosspoint inhibits. By pressing one input key and one output key, the user can toggle the force status of a single crosspoint.
The keypad can be used to scroll through the list of available ports and assign them to keys, and to change what setup pages are assigned to the panel.
The ARP-32 supports a maximum of 3 expansion panels, allowing for a total of 64 input keys and 63 output keys, in addition to the scroll key.
Pressing a single input key displays those outputs to which that input is forced or inhibited:
Similarly, pressing a single output key displays what inputs are forced or inhibited to that output.
Pressing the scroll key by itself has no effect.
If a single input key and a single output key are pressed, the force status for that crosspoint is toggled: If it was forced, the force is removed; otherwise the crosspoint is forced. Also, the same operation is performed on the reciprocal crosspoint. For example, if you press and hold an input key assigned to port 24, and tap an output key assigned to port 93, then (assuming the crosspoint is not currently forced) the crosspoint from input 24 to output 93 is forced, and so is the crosspoint from input 93 to output 24.
Although it cannot be used to view audio paths, the scroll key can be used to force or unforce crosspoints. In this case, it can be used as either an input key or an output key - it can be used with any other key, input or output, on the panel.
If a crosspoint (or its reciprocal) is inhibited, attempting to force or unforce the crosspoint has no effect. The ARP-32 cannot affect that crosspoint until the inhibit is removed via AZedit.
A crosspoint cannot be forced or unforced if either the input or the output port is a trunk port. (This is enforced by the ADAM MCII-e. If you try to force such a crosspoint, the port's LED will turn red briefly, but then will turn off again when the MCII-e rejects the request.)
In normal scroll mode, the scroll-up (6) and scroll-down (9) keys can be used to step through a list of available ports. The only ports which are displayed are those for which the LCP-102 scroll mode is enabled via AZedit.
Pressing the Prefix key (5) switches to Prefix scroll mode. In this case, scroll-up and scroll-down step to the next port with a different alpha prefix, the prefix being the first 2 characters of the alpha. Prefix scroll mode can be exited by pressing either the CLR key or the PGM key.
Initially, the panel scrolls through output alphas. The Inputs key (to the left of the 4 key) and the Outputs key (to the left of the 7 key) can be used to switch between displaying input alphas and output alphas.
Pressing the scroll key up clears the scroll window.
The Many scroll mode is entered when a key is pressed, and there are multiple ports forced to (or from) that port which do not appear on any keys. The scroll window displays Many initially; the scroll keys can then be used to step through the list of forced crosspoints. In this case, all forced ports are displayed, whether they are scroll restricted or not. However, ports which are scroll restricted cannot be copied to other keys.
Many scroll mode can be exited by releasing the (input or output) key, by pressing the scroll key up, or by pressing the CLR key.
In addition to the scrolling operations described above, the following key sequences are recognized:
The keys listed above are:
The MENU key provides access to two sub-menus (Display and Service) which implement various functions.
DIP switch #4 can be used to lock out the keypad. In this mode, the keypad can be used to access the Display menu, but cannot be used for anything else.
The ARP-32's key assignments and setup page assignments are stored by the ADAM MCII-e controller, and downloaded to the panel when it powers up. Changes made at the ARP-32 are automatically saved by the MCII-e. Changes can also be made via AZedit.
The DIP switches are used as follows:
The ARP-32 is currently supported by the following versions of firmware:
In AZedit version 3.2.0 or later, the PAP/LCP status screen will correctly identify ARP-32 panels; in earlier versions, ARP-32 panels will be shown as "???".
The ARP-32 cannot be downloaded when operating as an ARP panel. In order to download it:
