TW-800-EXS■General outline
This instruction manual describes "TW-800R-EXS" (hereinafter referred to as "receiver").
"TW-800R-EXS" is a receiver with RS-232C serial output specification of TW-800 series.
The RS-232C output extension unit is mounted to "TW-800R". Also, the receiver can communicate withmultiple TW-800T (hereinafter referred to as transmitter).
This instruction manual mainly describes the functions of the extension unit. For details about the functio
ns of "TW-800R" and "TW-800T", please refer to the "TW-800R Instruction Manual".
<Feature>◆The receiver can communicate with multiple transmitters by doing “pairing”.
The number of transmitters which can register pairing to one set of a receiver does not have restriction.
Receiver doesn’t remember ID number of transmitter. (It cannot read from a receiver ID of the transmitter which isregistered pairing, and how many set pairing is registered.)◆Receiver outputs the RS-232C data receiving from transmitter for special protocol.
Receiver sounds a buzzer simultaneously, when doing RS-232C output and it turns on a relay output.
(Buzzer sounds or not and relay out time is set by DIP switch)◆The RS-232C output from a receiver is performed by effluence. A flow control (RTS/CTS) is performed withconnection apparatus.
* "Pairing" used within this operation manual means the work which registers a transmitter and a receiver.

It needs doing “pairing” a transmitter and a receiver before using. The number of transmitters which can register
pairing to one set of a receiver does not have restriction.
ID number of receiver is memorized in transmitter. Transmitter transmits the signal included ID number of receiver.
Receiver can receive the signal attached ID number itself.
●Pairing (Registration)
1. Power Switch is turned on pushing the lighting switch.
To enter “Pairing mode” only 10 seconds with flashing the lighting switch for pairing.

The lighting switch for pairing

2. You continue pushing the “pairing switch” over 3seconds of transmitter by a long and slender thing.
3. It is completed the pairing between transmitter and receiver, then the lighting switch of receiver is turned off.
4. It can communicate with transmitter being pairing, you turn off the power switch of receiver once.
It needs to do a “Pairing” for every transmitter when you need to register a number of transmitters.
●Delete the pairing
At receiver is not “Paring situation”, transmitter cancels the paring information (registration information on areceiver) when the paring switch is pushed over 3 seconds continuously. By this operation, transmitter can notcommunicate a receiver is registered “Paring”.

*Caution
・When the signal from another transmitter is received while the receiver was carrying out the relay output, therelay output for transmitters received later is not performed. RS-232C output is performed respectively.
・When a receiver receives the signal from same transmitter during double count prevention time, relay output
time, and buzzer sound, a receiver does not process a signal but transmits the "BUSY" signal to a transmitter.
When a transmitter receives “BUSY” signal to a receiver, Green LED of transmitter flashes 4 times.
・When the signal from another transmitter is received while buzzer of receiver sounds, the buzzer sounds fortransmitters received later is not performed.RS-232C output is performed respectively.
・The receiver holds the data from a transmitter until each processing (a relay output and the prevention from adouble count) is completed. A limit is among the quantity which a receiver can hold temporarily, and when thesignal from the transmitter exceeding the number of maintenance limits of another ID is transmitted before eachprocessing was completed, a receiver may transmit the "BUSY" signal to a transmitter.
(When a transmitter receives “BUSY” signal to a receiver, Green LED of transmitter flashes 4 times.)
When you set up relay output time and double count prevention time in long time, please be careful.

12TW-800-EXS■How to use
1. Power switch of receiver is turned on. Please confirm the LED situation as turning off.
When the LED for receiving turns on, the transmitter is not registered by pairing. Please make a pairing withtransmitter.
LED for receiving (Green)(Lighting switch for pairing)
LED (Green & Red)

2. Transmitter transmits the signal at striking the limit switch by tightening the bolts from torque wrench.
When the communication is done normally, receiver output RS-232C output and receiver sounds the buzzer
and output relay output according to setting. Green LED of transmitter turns on 1 time.
When the communication is not done normally, receiver doesn’t move.
Red LED of Transmitter flashes 10 times
While the receiver output relay output or while receiver is in double count protect time or while buffer of receiveris full, receiver transmit the “BUSY” signal to transmitter. When the transmitter receives the “BUSY” signal, theGreen LED of transmitter is flashed 4 times.

TW-800-EXS●Test switch
There is a test switch for checking the battery and communication. When the transmitter transmits the signal bytest switch not limit switch, receiver doesn’t output relay output. But LED of receiver only turns on.
Also transmitter make a checking the battery at pushing the test switch. You can know the battery situation bytransmitter LED and Receiver LED.
The test switch also can be used as a pairing switch. A long press on the test switch (3 seconds or more) resets
the pairing with the receiver and prevents communication with the registered receiver. When pairing is reset by
mistake, perform the pairing procedure again.

TW-800-EXS●Battery level notification function
The battery level notification function notifies the battery level status in two stages.
①Notification of low battery level with test switch: It is possible to check the battery level with the test switch.
When the battery is low, the red LED will light for 1 second.
②Battery replacement notice: If the battery level is lower than in ① and the battery needs to be replaced,
the green LED flashing after transmission will change to an orange LED flashing.
When the orange LED blinks, please replace it with a new battery immediately.
When you replace the battery with a new one, the LED on the transmitter will return to green from the secondand subsequent transmissions.
Regarding the output data from receiver about battery level, "Test switch transmission (battery voltage low)" isnotified first, and then "Batteries need to be replaced" is notified when the battery level further drops.

For transmitters that support the battery level
notification function(battery replacement notice),■ is printed on the sticker.

TW-800-EXS■Note on use■Caution for communication
・If the transmitters transmit at the same time without any difference of 1 msec, one receiver can receive up to fourtransmitters.
・The receiver has a buffer that temporarily holds the data sent from the transmitter. The buffer can hold up to 5
data. While buffer of receiver is full, receiver transmit the “BUSY” signal to transmitter. Even if the transmittertransmits the data in this state, the data can not be output to RS-232C from the receiver, so it is necessary for theconnected external device to receive the data promptly.

■Caution for “Paring”
The number of transmitters which can register pairing to one set of a receiver does not have restriction.
Receiver doesn’t remember ID number of transmitter. It cannot read from a receiver ID of the transmitter which isregistered pairing, and how many set pairing is registered.
