Introduction:
CJ-TF series TTL/HTL fiber optic converter transmit
TTL/HTL signal through the optical fiber with long distant
transmission. Due to the use of optical fiber communication,
its can solve the electromagnetic interference, ground loop
interference and the lightning damage, greatly improve the
data communication reliability, security and confidentiality.
Its can be widely used in various industrial control, process
control and traffic control occasions, especially suitable for
oil, ports, electricity, transportation, mining and energy
industries.

Terminal Resistor
Resistor is to eliminate the effect of the signal reflected in
communication cable, as needed in the two end nodes of
the cable connection. Generally in high-speed
long-distance transmission, need to add the appropriate
terminal resistance at the two end of the cable, and let the
transmission line impedance matching. The terminal
resistance value in ohms (120-250), commonly associated
with transmission wire used.
Connection Method
1. Signal cable wiring methods: Encoder TTL /HTL optical
fiber converter is five-terminal; TTL/HTL electrical signal
input connected from the transmitting the pin T1/ T2 / T3 /
T4, signal by electrical transform to optical and send to the
receiving end equipment. TTL/HTL electrical signal restore
output at the receiving end T1 / T2 / T3 / T4. Feet T5 is
TTL/HTL electrical signal reference ground GND.
2. This equipment is belong to optical fiber transmission
products, the sending signal and receiving signal based on
optical definition. Please note that the transmitter receives
TTL/HTL electrical signals, after optical fiber transmission,
and the receiving end to restore the need of TTL/HTL
electrical signals.

1. Optical Connection: Fiber must be direct connection, that
is, TX end connect to the RX end. The encoder TTL/HTL
signal optical fiber converter must be used in pairs. As
shown in the figure below:
2. Power supply connection methods: This device support
dual power supply redundancy input, V1+, V2+ respectively
connect to the positive power supply (DC18 ~ 36 v), COM
connect to the negative power supply (dual power sharing).
Work can also pick up one of these power supplies. As
shown in the figure below:

DIN Rail Mounting
Using 35 mm standard DIN rail installation, in
most industrial applications are very convenient and the
installation steps are as follows:
Step 1: Check whether have the DIN rail installation tool
accessories (this product has been installed accessories).
Step 2: Check whether the DIN rail is fixed, is there a
suitable location to install this product?
Step 3: Connect the product accessories card DIN rail seat
upper card into the DIN rail (upper with spring support), and
then will connect the lower part of the card into the DIN rail
(upper card into a little, and put forth your strength with
balance of equipment get stuck into the bottom).
Step 4: The DIN rail clip into the DIN rail, then check and
confirm the product firmly into the DIN rail.

above high-quality copper
Optical port is not used, it must be with a fiber optic cap,
it will avoid polluted.
Do not look straight equipment optical fiber output port,
in order to avoid the laser damage eyes.
This equipment is belong to the precision of
communications equipment, please keep the ground
work of the equipment. Grounding device is a special
grounding screw on the side panel, when installation
should use the special earth lead, the earth lead must
be 2.5 mm2,, the resistance under 5 ohms.
