2-4. Serial Connection
The TRP-C08E has two DB-9 male connector and dual 4-PIN RS422/485 connector. The serial
port 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-C08E
serial port.
2-5. USB Connection
The TRP-C08E has a USB B-Type connector which is fully compliant with USB 2.0, the full rate
speed up to 256Kbps.
*Please using the USB 2.0 cable ensures the TRP-C08E working fine.
2-6. RS485 Wiring
The RS-485 mode supports the Transmit and Receive channels using 2-wire half-duplex operation.

2-7. RS422 Wiring
The RS-422 mode supports 4 channels with full duplex operation for Receive, Transmit, the data
lines are in differential pairs.
2-8. RS232 Wiring
The RS-232 supports 8 channels plus Signal Ground and is configured as DTE like a computer.
Signals are single ended and referenced to Ground. To use handshaking, Flow Control must be set
to RTS/CTS during configuration. Refer to the Pin out table for connections.

2-9. USB Cable Wiring
TRP-C08E is true USB 2.0 specification; it also supports USB V1.0, V1.1 standard. It is strongly to
recommend user use the standard A to B type USB 2.0 cable if USB1.0 cable can not work
properly.
3. TRP-C08E Software Installation.
Step1. Power on and plug USB cable to TRP-C08E.
Step2. Please download driver from http://www.trycom.com.tw/DOWNLOAD.htm. (See figure1)
Step3.Perform pl254x….exe.

3-1-1.TRP-C08E Device Installation & Detection:
Connect TRP-C08E to the USB Host controller of the PC using a USB cable. The first time you
plug-in the cable into the USB port, Windows will start installing the device driver software. You can
see the installation status at the pop-up message of system tray. After installation, the pop-up
message says “Your devices are ready to use”, Device driver software installed successfully.
TRP-C08E device detection can be confirmed by checking at the Device manager. Check for
“ High-Speed USB MultiSerial Compound Device” under Universal Serial Bus controllers and you
will find “High-Speed USB Serial Port (ComX)” under the category Ports (COM). Here ‘X’ in ‘ComX’
represents the serial port number. You can see the same in the figure below.
TRP-C08E device detection can be confirmed by checking the Device manager. Check for
“High-Speed USB Multi Serial Compound Device” under Universal Serial Bus Controllers and
“High-Speed USB Serial Port (Com X)” under the category Ports.
Now the TRP-C08E Device is ready to use.
