2-2. Serial Connection
The TRP-C38 has Four DB-9 male connectors. 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 COM port on a PC and the TRP-C38 serial port. A straight
through cable is required to connect the TRP-C38 serial port to a DCE device.
2-3. Power Connection
The TRP-C38 has a two pins terminal block and power jack. Power can apply on either terminal
block or the power jack. It accepts 10~48VDC/500mA power supply. When power is apply a red
light label as run will flash every one second to indicate the system is up and running.
2-4. Ethernet Connection
A straight-through Ethernet cable can be used to connect the serial server to an Ethernet hub,
switch, or wall plate. A crossover Ethernet cable can be used to make a connection directly to the
NIC (Network Interface Card) on a PC or laptop.
2-5. Reset Button
The reset button can be found between the switch and terminal block. To reset the unit manually
apply power, insert a small plastic tool, and press lightly depressing switch. Hold for 3 seconds
and release. The Link and Run light will go out and turn back on. The TRP-C38 will revert to the
last setting.
2-6. Dip Switches
A double DIP switch allows the TRP-C38 to be placed into Console/Loop back/Default/Data
Mode.
When all these switches are moved into the ON position, theTRP-C38 enters Console Mode,
allowing configuration of the TRP-C38 from a PC running a terminal program such as
Hyper-terminal. When the TRP-C38 enters Console Mode, the Console Mode screen will appear
in the Hyper-terminal program window. The serial port settings must be 8-N-1 at 9600 baud.
When the DIP switches are switched to the ON OFF position, the TRP-C38 will work at Loop
back Mode, all data is sent back immediately.
When the DIP switches are switched to the OFF ON position, the TRP-C38 will revert to its
factory version firmware no matter what newer firmware has been upgraded.
