1. Introduction.

Based on Bluetooth technology TRP-C51 allows you to wirelessly connect your RS-232/422/485
devices to systems within the range up to 100M, TRP-C51 features wide range power input, auto
RS-232/422/485 signal switching and internal surge protection on RS-422/485 lines. It also
supports all common data format and baud rate which can be configured by the bundled TRP-BT
utility from Windows system. TRP-C51 can operate in “Direct link mode” and “Paired mode”
When in paired mode, the user just need to power two devices, and they will automatically
connect without software and hardware changes on your systems that will replace your serial
wire with a completed transparent wireless connection. It can be used for wide range of
applications for wireless operation and monitoring process.

PWR LED:

When power is properly supplied to TRP-C51, the PWR LED will on.

LINK LED:

TRP-C51 can be configured as Master mode or Slave mode. When TRP-C51 is in Master mode,
the LINK LED definition is as below.

A: Turn on/off in 150ms cycle – when TRP-C51 is in slave searching status.
B: Turn on/off in 1000ms cycle – When TRP-C51 is in slave connecting status.
C: Turn on— Master and Slave connection is successful.
D: Blinking— if there is activity such as data transmitting or receiving.

When TRP-C51 is in Slave mode the LINK LED definition is as below.
Turn on/off in the cycle of “1000ms on/ 3000ms off” – no connection.
Turn on— When Slave and Master Connection is successful.
Blinking— when there is activity such as data transmitting or receiving.

TX LED: RS-232/422/485 data transmitting.
RX LED: RS-232/422/485 data receiving.

2-4. DIP Switch.

There are 2 dip switches on TRP-C51. One 2-pin dip switch is for system configuration, another
is a 4-pin dip switch for extension and no function.

2-4-1. The 2-Pin DIP-Switch for configuration mode.

SW1,2: OFF OFF: Normal mode
SW1,2:ON ON: Configuration mode

SW1,SW2: OFF OFF -- Normal mode.
TRP-C51 can only work in normal mode. In this mode all system setting are completed.

SW1,SW2 : ON ON -- System configuration mode.
This mode is for system configuration change. When adjust the switch to ON/ON position
TRP-C51 will stop all activities. User may run TRP-BT utility to change the baud rate, data format
or the other settings. After the configuration change completed, revert the switch to OFF/OFF
position and reboot the system. All the system changes will be effective after the system reboot.

2-4-2 The 4-Pin DIP-Switch for option.

No function.

2-5 Micro Touch button.

TRP-C51 micro touch button provides user with “new link” function when user want to drop
existing connection and create a new connection with new device.

The Micro touch button can only work when TRP-C51 is defined as Master. When TRP-C51 is in
Slave mode the button is no function.

The Micro touch button is no function, if TRP-C51 already had default “BD address”

3.Install TRP-C51.

3-1. Serial Connection

The TRP-C51 is equipped with one DB-9 male connector which is configured as a DTE (data
terminal equipment) device. All PC COM ports are DTE ports.

A null modem cable is required to make a connection between the PC COM port and the
TRP-C51 serial port.

3-2. Power Connection

The TRP-C51 is equipped with a 2-pin terminal block and power jack. Power can be supplied
from terminal block or external DC plug. It support wide input range from +10~+30V DC/500mA
power supply. When power is correctly supplied the PWR LED will turn on and the system is
ready.

If the power input from external *Please use the power plug specification. (5.5*2.1*12 mm).

Warning: User can only choose one of following 2 power sources.

1. External DC adapter. 2. Screw terminal DC input
Do not use both power input simultaneously.

3-3. RS-232 wiring connection.

3-4. RS-485 wiring connection.

The RS-485 mode supports the Transmit and Receive channels using 2-wire half-duplex
operation. Refer to the pin assignment for connection as below.

The

RTS/CTS must be “none” if using the RS-422/485 function, please refer to chapter 4-2 step10

3-5. RS-422 wiring connection.
The RS-422 mode supports 4 channels with full duplex operation for Receive and Transmit, The
data lines are in differential pairs. Refer to the pin assignment for connection as below.
