Explanations:
SETUP-MODE:
Scanning mode for recognising installed monitors.
NORMAL-MODE:
Regular operation mode.
Master Central Unit:
External Line controller in case of multiple Central Unit operation, another Central Unit will be assigned
as a master unit when default master unit is disabled.
Program button:
This button which shown in figure 2.1-A is used to SETUP Mode or NORMAL Mode implementations.
Function LED:
This is a multi-colored indicator LED which shows devices MODE and current function. Color meanings
described below.
*RED:
Shows Central Unit is in start-up or ready to reset.
*BLUE:
Central Unit provides 24V to other devices while NORMAL MODE, Central Unit scanning in proggress for DIP Switch
based ID configuration while in SETUP MODE.
*GREEN:
Central Unit is activated in NORMAL MODE, Central Unit scanning in proggress for DIP Keypad based ID configuration
while in SETUP MODE.
*GREEN-YELLOW FLASH:
If you see a flashing yellow signal during continuous Green signal it means Central Unit is a
maste Central Unit.
Status Indicator LEDs:
Status LEDs shows currnet operations in Central Unit as shown in Figure 2.1-C.
* LED Shifting-light:
Central unit is in Setup Mode.
* Sliding LED signal in Sequence:
Central Unit is in setup mode. Stepped signal when Program button is pressed: Current
operation is not completed yet, it is a must to keep program button pressed until all LEDs are illuminated.
RS232 communication:
This connection let the user to see Central Unit records via USB interface shown in Figure 2.2-A.
Digital output:
Used for communication with other units shown in Figure 2.2-B.
Be careful to make sure all ID depended devices are set with unique IDs including Central Unit before the
system is energised. In order to multiple Central Unit operations, be careful that all Central Units are set
diffrent IDs different from “0”.
Please refer Table 2.1 for ID settings.
