2.4 Laserlight2 CPU Board (PN 169279)
Figure 2-5. LaserLight2 Remote Display CPU Board
Port 0, which is connected to the indicator, supports three configurations; 20 mA, RS-232, and RS-422
communications. Port 1, which is the Echo port, does not support 20 mA but does support RS-232
communications.
2.4.1 20 mA Current Loop
The 20 mA current loop communication is provided on connector J6 of the CPU board (Figure 2-5 and Table 2-2). Make
sure to select active or passive switch settings.
2.4.2 RS-232
The RS-232 connection is provided on connector J8 of the CPU board (Figure 2-5 and Table 2-2).
2.4.3 RS-422
The RS-422 connection is provided on connector J9 of the CPU board (Figure 2-5 and Table 2-2).
2.4.4 Reset Switch
The reset switch enables a simulated power up reset, eliminating the need to unplug the unit to perform a reset. The unit then
goes back to normal operation mode. Refer to Figure 2-5 for the reset switch location on the CPU board.
2.4.5 Communicating with Indicators and LEDs
Small LEDs located on the CPU board flash when serial data is received or sent. The transmit indicators flash when
data is sent out of the port. The receive indicator flashes when data is received. A steady indicator on any receive
LED reflects a connection with no streaming data.
