GPI/Connector Module
Figure 1.2
Provides connectors for two line-level audio inputs (program 1 and 2), an unswitched, balanced
microphone preamplifier output, an external headset, an external speaker output, and a foot
switch input (for remote switch activation of all "armed" talk keys, or just one key). Also includes
a General Purpose Input / Output (GPIO), with four opto-isolated inputs, two open-collector
outputs, and two SPDT relay outputs. Inputs can activate single keys, groups of keys, or change
setup pages. Outputs can activate external devices from keypanel keys or from GPI inputs.
Available factory installed or as an add-on kit.
CSI-100 Coaxial System Interface Module
Figure 1.3
Provides the ability to link the unit to the matrix using a single 75 ohm coaxial cable. The
interface converts all audio and data streams to a single transmission path. Perfect for systems
where there are existing, but unused 75 ohm video cable. Requires a CSI-200 interface unit at the
intercom matrix end.
