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.

 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.

 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.

 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.

 At the wall block wire the transformer to pins 3 and 4. Polarity is unimportant.

 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.

 Set the keyboard DIP switches according to the instructions in the

Switch Settings

section.

 Plug in the keyboard data cable.

 Plug the KBDKIT or KBDKIT-X transformer into a suitable outlet. The LED display shows number 1,

which is the default camera number.

 Go to the

Programming and Operation

section and program and test for proper operation.
