# Feature Function

1 REL Terminal Block (from 1 to 4) Connect to room items

. The PINOUT is: NO: Normally Open;

C: Common Voltage; NC: Normally Closed

REL Terminal Block (from 5 to 8) Connect to room items

. The PINOUT is: NO: Normally Open;

C: Common Voltage

3 RS-232 Terminal Block Connects to the RS-232 port on a PC

4 K-NET™

PIN GND is for the Ground connection Terminal Block

Connector

; PIN B (-) and PIN A

(+) are for RS-485, and PIN +12V is for powering the unit

LINK LED Illuminates when a link is established

6 ON LED Illuminates when receiving power

Figure 2 and Table 2 define the underside of the PL-8. On some units the

printing of the labels “RS-485 T

ERM” (instead of “PROGRAM”) and

“P

ROGRAM” (instead of “RS-485 TERM”) may be swapped around

erroneously. The correct labeling is defined in Figure 2 and Table 2.

1 CONTROL DIP-switches

Set DIP 8 ON to use protocol 2000

Set DIP 8 0FF to use protocol 3000 over K-NET™

2 RS-485 TERM Switch Switch for line termination of the unit

3 PROGRAM Switch Switch to PROGRAM for firmware upgrade

1 Such as lighting, screen settings, blinds, and so on

2 K-NET is a proprietary Kramer protocol for interconnecting Kramer units

3 The ground connection is sometimes connected to the shield of the RS-485 cable (in most applications, it is not connected)
