User's Manual

Connect a microphone cable to the male 3-pin XLR connector on the rear of the FS II Base
station, and connect the other end to the external audio system. When the output is activated,
the beltpack user’s voice will be sent at line level to the audio system. The audio output
ceases when the beltpack user stops pressing the rotary encoder; it is good practice to make
sure that any rotary encoder to which the SA OUT is assigned is set to momentary/non-
latching mode.

The associated SA RELAY can be assigned to open an audio route for the paging or
announcement, or can be assigned to initiate any other event such as turning on a light or
activating a lock. It is rated at a maximum of 30 VDC at 1 ampere. The relay can be wired to
be either normally open or normally closed, using the pinout information in Table 4-5 Pin

4.8 Connecting to a PC
4.8.1 Connecting using the serial port
The PC serial port on the rear of the FS II Base station is mainly used for firmware version
upgrades of the system.
A specially wired cable is required for these updates, consisting of two 9-pin D-type
connectors for the PC and the FS II ends. On the FS II end, a male 9-pin D connector is used,
and is wired as follows in relation to the D connector pins on the PC end. Pin 2 goes to pin 3,
pin 3 goes to pin 2, and pin 5 goes to pin 5; in other words, the data Tx and Rx lines on pins 2
and 3 are reversed. Those are the only wiring connections on the FS II end of the cable.
