[ 6 ] Pelco Manual C519M-D (7/00)
10 Turn on the power switch on the back of the keyboard. The monitor comes on.
11 Go to the
Programming and Operation
section and program and test for proper operation.
INSTALLATION - DIRECT MODE
Direct Mode is for a single-keyboard installation only. The keyboard is wired directly to a maximum of 16
receivers. Direct Mode installation/operation is not the same as CM6700 Mode installation/operation. A
separate system, such as an MS500 or VA6100 switcher, is required for routing video to the monitor(s).
To connect the keyboard (refer to Figure 3).
1 Make sure all receivers are configured to communicate using Pelco P protocol at 4800 baud and that
each receiver has a unique address. Refer to your receiver manual for switch settings.
2 Decide on a suitable location for the keyboard and interface module. The interface module must be
within 6 feet (1.8 m) of the keyboard and of the nearest suitable electrical outlet.
3 Attach the KBD300V Interface module to the wall with the provided screws. Remove the cover, if nec-
essary, and replace when finished.
4 Receiver wiring should be in place before installing the keyboard. You can control up to 16 receivers
from the keyboard.
Communication to the keyboards is RS-485. Maximum cable distance for RS-485 communication
over 24-gauge wire is 4,000 feet (1,219 m). Pelco recommends using shielded twisted pairs cable
that meets or exceeds the basic requirements for EIA RS-485 applications.
5 Refer to Figure 3. Make receiver cable connections to the COM OUT terminals on the interface module.
• Connect the TX+ terminal from COM OUT on the interface module to RX+ on the receiver.
• Connect the TX- terminal from COM OUT on the interface module to RX- on the receiver.
• Connect the ground terminal to the ground terminal on the receiver. (A ground connection
may not be necessary if another ground path already exists).
6 Connect a video coaxial cable from the video out jack on a video switcher to the VIDEO IN jack on
the interface module.
7 Set the keyboard DIP switches for Direct Mode according to the instructions on page 8.
8 Connect the keyboard data cable between the interface and the keyboard.
9 Connect the power supply to the interface and plug the transformer end into a suitable outlet. The
LED display shows number 1, which is the default camera number.
