The two function keys can be programmed to perform any command in the system. Effectively they are
programmed with a remote control command. This means they can also perform inband control of the remote
codec as well as the local codec. The Function keys will override the DIP Switch settings currently set on a NICA X-
1 unit.
The function keys are programmed either from the front panel keypad and display (see section 5) (NICA X-2) or
from the remote control port (see section 8). The function keys can be set to perform a latching or momentary
type action and can also perform an A and B command relating to the key press.
Here are some examples :-
1. If set to latching action, pressing the key will perform command A and releasing the key will perform command
B, e.g. Loopback ON when key depressed, Loopback OFF when key released.
2. If set to momentary action, pressing and releasing will perform command A and pressing and releasing again
will perform command B, e.g. pressing the key will toggle between one mode and another mode.
3. If F1 and F2 are set to latching action, with just command A used on both F1 and F2, pressing and releasing F1
could dial a Book entry, and pressing and releasing F2 could clear down all ISDN calls.

The external inputs are 8 optically isolated inputs (see Appendix A.5 for connection details). The external inputs
can be programmed to perform any command in the system. Effectively they are programmed with a remote
control command. This means they can also perform inband control of the remote codec as well as the local codec.
The external input command will override the DIP Switch settings currently set on a NICA X-1 unit.
The external inputs are programmed either from the front panel keypad and display (see section 5) (NICA X-2) or
from the remote control port (see section 8). In a new system they are factory set to perform dial of BOOK entry
101 on input 1 through to dial BOOK entry 108 on input 8. These, of course, can be changed to any command.
The external inputs can be set to perform a latching or momentary type action and can also perform an A and B
command relating to the active or inactive state. Here are some examples:-
1. If set to latching action, taking an input high will perform command A and taking it low will perform command
B, e.g. Loopback ON when active, Loopback OFF when inactive.
2. If set to momentary action, pulsing an input high to low will perform command A and pulsing again will
perform command B, e.g. pulses will toggle between one mode and another mode.

The external outputs are 8 relays with Normally Open contacts with one shared common connection (see Appendix
A.4 for connection details). Each external output has a default setting as listed in the table below or it has a USER
setting. The USER setting allows the Relay to be switched by a programmed event in the system. For example an
opto input on a remote NICA X could be programmed to switch a relay on the local NICA X.
