TS-ENC200 Manual
• COM 2: COM2 is brought in from the base SBC. This RJ-45 connectors use the pin-outs
established by the EIA/TIA 561 specification for RS-232. The TxD, RxD, RTS, CTS, and
ground pins are supported for RS-232 communications.
The RS-232 com port labeled COM2 supports pins 4 through 8.
Pin 1 is the first pin on the left of the
connector when holding the enclosure
upright, looking at the back-side of the
enclosure.
• COM3: This COM port is in addition to the enclosed SBC's COM port. It is an optically
isolated RS232 with support for RS485 or RS422. It supports the same pin-out configuration
on the RJ-45 connector as COM1.
• 20-30VDC: The three-pin connector accepts 20-30VDC of external power to supply power
to the board
• Power Indicator Light: The LED indicator in the back of the enclosure is the power LED. It
is turned on anytime power is applied to the unit.
• Ground Lug: The lug labeled with the chassis ground symbol is used for chassis ground.
• MODEM: The RJ-11 connector is used for the optional modem and accepts a standard
telephone-line cable

• Status LED: The status LED is located on the front of the board, and is both a Red and
Green LED. The Red LED is directly connected to the processor (user) LED of the enclosed
EPC. DIO 2, pin 14, controls the Red LED. See you enclosed EPC's manual for how to
control both LED in software. The Green LED can be controlled by accessing IO location
193, bit 0. Writing a 1 will turn it on, writing a 0 will turn it off.
