Relay/Opto/AUX(D) connector (25-pin male D-type)
This has been applied to BS1000 version V3516.
Pin1~4, Pin14~17 are reserved for connection with other devices. Supply 12 VDC to other devices.
Opto-isolated Inputs
Base Station provides two optically isolated inputs.
You can trigger Talk keyls by connecting the foot switch or other control to the Opto-isolated Input.
Each input consists of a pair of pins (pin 8/21 or pin 9/21) with an operating range of 5 VDC to 20 VDC. The
inputs are operated by applying a voltage between 5 VDC and 20 VDC across the pins and is detected by the
opto-coupler. The voltage may be derived from the Base Station itself using the 12V (pin 14,15) and 0V (pin 16,17)
pins or it may be from an external source.
These inputs can be used for user programmable functions such as switching a Talk on or off.
Assign this Opto-isolated input to the Talk keys. When this input is detected, the corresponding Talk keys are activated.
You can assign one Opto-isolated input to multiple Talk keys. One Talk key can be assigned Opto-isolated input functions
with GENIE group channels.
Relays
The Relay output allows the use of a Talk key to trigger any external device that allows standard contact
closure. The Relay can activate an external device, such as a cue light, or a walkie-talkie. All Relay contacts
can support 1Amp 30 VDC. Base Station does not supply any power to the circuit.
Base Station provides three Relay outputs. One is activated by pressing the SA button. Press the SA button to
activates a Relay 7 (SA) pin. Two Relays can be allocated to the Talk key. The Relays can be set on Talk channel
1 to 8. When the Talk key set to Relay 1 is pressed, Relay 1 (pin 5,18) is activated. In the same way, pressing the Talk
key set to Relay 2, activates Relay 2 (pin 6,19). Relay cannot be set on one Talk key with a GENIE group channel.
AUX D (unbalanced audio)
Pin 12,13,24,25 are unbalanced audio signal pins that are shared with Line D (4-wire). If this AUX D is used,
4-wire Line D shall not be used.
These pins can be connected to a gooseneck microphone or a walkie-talkie, etc. In some cases, additional
connections such as resistor may be required when connecting a specific walkie-talkie.
