product has solved the problem of contradiction between communication distance and communication
rate of traditional serial port. At the same time, it also has solved the problem of electromagnetic
interference, earth link disturbance and thunder/lightning destruction, thus greatly enhancing reliability,
security and privacy of data communication. It can be widely used in various kinds of situations such as
control, process control and transportation control, and especially suited in bank, electric power as well as
departments and systems which have special request to the electromagnetic interference environment.
1.2 Features Based on self copyright IC.
RS232/485/422 interface can be optional by dip switch.
Serial port supports 0-57600bps auto-negotiation.
Combination of PDH technology and digital lock loop clock technology.
Unique serial port for circuit protection, supporting hot-plugging.
Data transmission is stable and reliable with integrated light-receiving and transmitting module.
Complete surface paste and install craft, grade design, and production-runs with piece-pasting
machine.

2.1.2 Test buttons There are four buttons on the front panel, as follows from the left to right:
ANA: self loop in local fiber interfaceused to check whether local device and its connecting line work normal.
DIG: self loop in local RS232/485/422 interface, used to check the remote device and optical wire.
REM: command remote RS232/485/422 loop
PATTPBRS Code testing. To produce and transmit the PBRS to the E1 output port, and check
whether the input signal of E1 match that PBRS standard. If match, the PTOK light on, otherwise,
off. By this way, the status of the fiber circuit can be tested.

When loop circuit 1 is on, confirming of local device working well is available; loop circuit 1 off and
loop circuit 2 on, confirming fiber transmission line and both devices work well is available.
Note:
The function for the combination of button switch:
A) Local ANA+ local PATT (when both buttons pressed at the same time) PBRS code test local device, if PTOK on, means ok; if off or flick, it means failure.
B) Remote DIG + local PATT (when both buttons pressed at the same time) PBRS code test local, remote device and fiber, if PTOK on, means ok; if off or flick, it means
local device failure.
C) Local REM + local PATT (when both buttons pressed at the same time) PBRS code test local, remote device and fiber, if PTOK on, means ok; if off or flick, it means
local device failure.
Push down any switch on front panel will terminate the normal communication, and turn into the
test mode.
During the PATT model testing, there should be loop-line, otherwise the PATT code cant come
back.

* Check power supply configuration. Care about the value of voltage if using DC input.
* Take following tests before usage:
A. Connect RX and TX optical interface of one device with pigtail, LNK light should be ON.
B. Connect RX-TX, TX-RX optical interface of two devices with pigtails, both LNK lights of two devices should be ON.
If device does not work well, please contact us or our local agent in time.
4. Trouble shooting serial Symptom Possible Problem Possible Solutions
1 LOS on Optical signal loss Check the optical signal, fiber connector

on RX terminal clean or not, fiber break or not, opposite device power on or off. Loop back the fiber input and output connectors with the fiber connecting. The light off means the device work well, then please check the opposite device and fiber.
2 LOS off, while the LOF on
Optical signal frame not in-phase
The optical connector clean or not; the input optical signal exceed the receiving sensitivity of this device or not; the input optical signal from the correct source or not(check the connecting on the fiber assort frame especially)
3
the light work
correctly, but
no data
maybe the
problem lies in the
fiber transmission
channel
Press the PATT and REM buttons,(or make the opposite device loop back the
RS232/485/422 data), if the PTOK light off, it means the fiber transmission
channel have problem.
4
All the LED normal ,but loss of data
Fiber channel may have problem
Press REM and PATT (or tell remote terminal to loop back local terminal), if PTOK is OFF, then the fiber channel have problem.
5 If push down PATT, PTOK is OFF, then push down ANA, PTOK is ON, then the device work normally
6 If push down PATT, PTOK is OFF, then push down REM or push down DIG on the remote device, PTOK is ON, then both devices and fiber channel are work normally.
