PWR
Power indicator
Power on when work normally.
ANA
Analog channels
(current, voltage) state
indicator
1. Off--no analog signal (I/V) input or output.
2. Blinks--when there are input/output channels and its values are in the
normal range between (4-20 mA / 0 – 5V/ 0-10V).
3. On--when there are input/output channels and its values are over the
normal range.
OPT
No optical and data
receiving indicator
1. On—optical module no receiving channel or abnormal.
2.
Blinks—optical module receiving channel normal and has data
receiving.
3. Off—optical module receiving channel normal, but no data receiving.
DIGI
Digital channel
receiving indicator
(dry contact or TTL
signal)
1. Off—the device has no digital signal input function.
2. On—the device has digital signal input function.
COM1-2
Serial port state
indicator
1. Off—no data receiving on corresponding serial port.
2. On—receiving date on corresponding serial port.
Analog/digital/serial
This series product can choose 1 ~ 4 chs analog signal, 1 ~ 4 chs digital signal, 1 ~ 2 chs serial signals independently using or
division multiplexing, which realize one-way or two-way optical fiber transmission. To describe the direction of signal transfer for
convenience, it makes artificial distinction between optical transmitter and optical receiver. The equipment should match with
each other and every port must connect with the right one correspondingly when using. The factory should arrange the
production according to the goods requirement and the right channel order named 1, 2, 3, and 4.
