Mutes the speaker. Default positions are 1 and 2 (speaker is not muted). 

Testing interface (debugging) for the RS-232 signals. 

Changes the speed of the driver. For Multi-Tech use only. Default positions are 1 and 2 
(transceiver operates normally). 

JP6 & JP9 are the 5V / 3.3V regulators. The operating voltage factory default setting is 3.3V.  
JP1 jumper must be set to 3.3V.  
Warning – Be sure to that 5V / 3.3V jumper is set to match the requirements of your 
SocketModem. If this jumper is set incorrectly, damage to the SocketModem and/or the 
Test/Demo card could result. 
Caution – Use only the provided Multi-Tech Systems, Inc. transformer with the Test/Demo 
board. Use of any other power source will void the warranty and will likely damage the 
Test/Demo board and the SocketModem. The transformer connector is keyed to prevent 
improper connection to the Test/Demo board.  

Testing interface (debugging) for the serial TTL signals. 

Enables/disables the Watchdog interface. 

100 OHM terminator for ISDN. Default positions are 1 and 2 (off).
