Instruction manual

DTR Jumper, J11 This jumper is used to enable the dial-up mode.
The dial-up mode can be enabled only when the DV-MUX3 main link interface
uses the RS-232 interface. For other interfaces, the dial-up mode is not available,
irrespective of the setting of this jumper.
The jumper has two positions:
CNTL When the RS-232 interface is selected, the dial-up mode is en-
abled. In this case, the DV-MUX3 controls the state of the DTR
line in the main link interface as explained in para. 1-2.
ON The dial-up mode is disabled, and the DTR line in the main link
interface is ON as long as the DV-MUX3 is powered.
The default setting is ON.
CHASS Jumper, J10 This jumper controls the connection between the signal ground lines to the chassis
ground line. The appropriate position must be determined by the installation man-
ager. The jumper has two positions:
CON signal ground connected to chassis ground.
DIS signal ground disconnected from chassis ground.
Factory setting is CON.
