Pelco Universal Keyboard KBD300A - Manual (Page 24)

[ 24 ]
Pelco Manual C527M-L (3/04)
INSTALLATION – DIRECT MODE
The keyboard is wired directly to a maximum of 16 receivers. You can communicate using Pelco P Protocol
or Pelco D Protocol. Direct Mode installation/operation is not the same as CM6700 Mode or CM6800
Mode installation/operation. A separate system, such as an MS500 or VA6100 switcher, is required for
routing video to the monitor(s).
In Direct P and Direct D modes you can now change the zoom speed of a PTZ by entering a number from 1
to 4 followed by a zoom command. This causes the zoom speed command to be sent.
NOTE: A KBDKIT or KBDKIT-X is required to use the keyboard in Direct Mode. The KBDKIT consists of
two RJ-45 wall blocks and a 120 VAC to 12 VAC transformer. The KBDKIT-X is for 230 VAC. Only one wall
block is required for this application.
Connecting the Keyboard
Refer to Figure 10.
ᕡ
Make sure all receivers are configured to communicate using either Pelco P or Pelco D protocol and
that each receiver has a unique address. Refer to your receiver manual for switch settings.
ᕢ
Decide on a suitable location for the keyboard and wall block. The keyboard must be within 25 feet
(7.6 meters) of the wall block. The wall block must be within 6 feet (1.8 m) of the nearest suitable
electrical outlet. Do not mount the wall block at this time.
ᕣ Remove the cover from the KBDKIT or KBDKIT-X wall block. Connect the transmission wires from the
receiver (Spectra/Esprit system) to the wall block. Refer to Figure 10 and do the following:
• Connect RX+ from receiver/driver to TX+ (terminal 1) on the wall block.
• Connect RX- from receiver/driver to TX- (terminal 2) on the wall block
NOTE: Communication to the keyboards is RS-422. Maximum cable distance for RS-422 communica-
tion over 24-gauge wire is 4,000 feet (1,219 m). Pelco recommends using shielded twisted pair cable
that meets or exceeds the basic requirements for EIA RS-422 applications.
ᕤ
At the wall block wire the transformer to pins 3 and 4. Polarity is unimportant.
ᕥ
Replace the cover on the wall block. A double-sided sticky pad is provided to mount the wall block.
Secure the wall block to a suitable surface.
ᕦ
Set the keyboard DIP switches according to the instructions in the Switch Settings section.
ᕧ
Plug in the keyboard data cable.
ᕨ
Plug the KBDKIT or KBDKIT-X transformer into a suitable outlet. The LED display shows number 1,
which is the default camera number.
ᕩ
Go to the Programming and Operation section and program and test for proper operation.
