INTERNAL JUMPER SETTINGS FOR PTZ PORT

ENABLE JUMPER:

The ENABLE jumper (See Figure 3) forces the RS422 line drivers to be

continuously enabled when installed. When this jumper is left open, the line drivers are enabled

only during data transmission. When left open, the drivers are enabled by the output of a a one-

shot that is triggered on the negative going edge of each bit and lasts for 3-4 character times at

300 baud for full duplex operation.

PROTOCOL JUMPERS:

Two PROTOCOL jumpers (See Figure 2D) allow the DVMD1 to drive

either RS232 or RS422/RS485 type PTZs. These two jumpers must always be moved as a pair.

The RS232 protocol is selected when these jumpers are connected from the CENTER to the

LEFT posts. The RS422/RS485 protocol is selected when these jumpers are connected from the

CENTER to the RIGHT posts.
