BACK PANEL WS880:
1. Antenna A Input: TNC connector for dipole antennas (included), front-to-back antenna cables (included), or
antenna cable to active extension antenna.
2. Antenna A Output: Daisy-chain to the input of another receiver-frame to form an antenna network.
3. Power Cord Input: (Cord with local plug configuration Included). 100-240 VAC, 50/60Hz, 15 W, 250V 320mA
slow-blow fuse (spare included)
4. Ethernet: Connect to a computer or network. Multiple receiver-frames can be daisy-chained together to form
a network. (Under construction)
5. GPIO/RS232: This connector combines a General Purpose Input / Output (GPIO) and a RS232 on one
DB25 connector. The RS232 can be disabled to add up to 24 GPIO pins.
RS232: The pinout for the RS232 is the standard pinout. Pin 2 on the receiver is transmit, pin 3 is receive,
and pin 7 is ground. Most computers now use a DB9 connector for RS232. The standard off-the-shelf DB9
to DB25 cable will work. This cable swaps pins 2 and 3 internally. If you computer has a DB25 connector for
RS232, use a straight DB25 to DB25 cable. Do not use a null modem cable.
GPIO: GPIO acts like a contact closure. Use ClearOne Remote to assign an event that toggles the GPIO
pin. The factory default toggles pins X through X to correspond to muting a receiver module. ClearOne
Remote has a feature that lets you assign how the system responds to a transmitter mute (see ClearOne
Remote)
A. Mute the channel’s receiver audio. (Factory default)
B. Toggle the GPIO but do not mute the receiver audio. Use this with automated mixers or echo cancelling
DSPs.
C. Mute the channels receiver audio and toggle the GIPO pin.
6. Audio Output Jacks: Configured for four or eight-module receiver frames and for XLR or Euro-block terminal
connectors.
7. Antenna B Input: TNC connector for dipole antennas (included), front-to-back antenna cables (included), or
antenna cable to active extension antenna (see section on antennas, antenna placement and antenna cables).
8. Antenna B Output: Daisy-chain to the input of another receiver-frame to form an antenna network.
