For a Supervisor Panel fitted with a PDE4537 options card, a button or switch connected to GPI #3 can

be used to terminate a mimic/control session. Any switch transition detected on GPI #3 causes the

current session to be terminated.

4.12.4 Supervisor Facilities

When a valid target panel has been selected, the Supervisor Panel display and LED Status switch over

to mimic the current display and LED Status of the target panel.

4.12.4.1 Key Presses

All Supervisor Panel key presses, except for the auxiliary volume control pot switch (i.e. INFO key), are

transferred to the target panel, as if pressed at the target panel. The target panel responds to local key

presses and key presses transferred from the Supervisor Panel.

When the same key is pressed or held simultaneously on the Supervisor and target panels, the first key

action to be detected causes the key press action to take effect. The last key to be released causes the

release to take effect.

4.12.4.2 Cross-point Level Control

Cross-point level control affects the level of incoming audio routes to the target and Supervisor panels.

A Supervisor Panel and target panel both have the ability to control the cross-point levels.

The cross-point level is determined by the 'last moved' rotary encoder. For example, if the Supervisor

Panel is used to turn a cross-point level down to 0.0, then the target panel is used to turn the same cross-

point level up to 10.0, a further movement of the Supervisor Panel control 'jumps' the level back down to

0.0 again. The level bar indicator on the Supervisor and target panel keys always shows the actual cross-

point level.

When using a Supervisor Panel to control either a PD4221 or PD4211 target panel type (i.e. LCD key

panels with a single rotary encoder above the REPLY key), the rotary encoders above the supervisor

panel DAKs do not control the cross-point levels of the associated DAK. The supervisor panel mimics

the target panel operation, so the rotary encoder above the REPLY key needs to be pressed to invoke

cross-point level control mode on the target panel. Cross-point level control can then be performed at

the supervisor panel by pressing the desired DAK and turning the REPLY key rotary encoder.

4.12.5 Audio Monitoring In Supervisor Mode

4.12.5.1 Supervisor Panel

All audio routes to and from a Supervisor Panel, prior to the selection of a target panel, are removed

while the mimic/control session is active. The routes are restored when the mimic/control session is

terminated.

New calls to a Supervisor Panel are not routed to or indicated to the Supervisor Panel until after the

mimic/control session has been terminated.

4.12.5.2 Target Panel

New calls to a target panel are duplicated at the Supervisor Panel unless the rack set-up inhibits the

routes (e.g. permanently open cross-point).

4.12.5.3 Indication To Third Parties

A third party panel making calls to the target or Supervisor panel during a mimic/control session will not

receive any indication that the destination they are calling is currently in a mimic/control session.

4.12.5.4 System and Panel Resets

After a red button reset the Supervisor and target panels maintain the mimic/control session.
