USB ports
The J2 615 has four external and two internal USB 2.0 ports. The four external ports are
located in the cable well. In addition there are two internal USB ports used as follows:
one is used for the optional Finger Print Reader and is located on the MSR connecting
point; the second internal USB port is used for the IR touch screen controller in the IR
version of the 615 unit.
USB Ports
Ethernet Connection
The J2 615 uses the Realtek 8111 Gigabit Ethernet controller. The Ethernet connector is
located in the cable well (
shown below)
. The Ethernet controller supports Wake On LAN,
the BIOS supports a PXE Boot ROM as well.
Ethernet Port
Serial ports
The 615 unit has four external RS232 serial ports, two of which can be powered; COM3
and COM4. The serial ports use a ten pin RJ45 connector. The unit comes standard with
two serial cables, one RJ45 to DB9 adapter cable, and a 5 foot RJ45 to DB25 serial
printer cable that works with EPSON and EPSON compatible printers. Additional cable
adaptors can be order from J2.
Both serial (COM) ports 3 and 4 can be strapped to provide power to external devices.
The J2 615 is shipped standard with serial 4 strapped to 12 to pin 9 of the DB9
connector. Normally serial port 4 is used for J2’s 2x20 character VFD customer display
which gets its power from the serial port. If another device is used on serial port 4 it is not
required that this jumper be changed because most all serial devices do not use pin 9 (RI).
(Note that even if it does the added device can handle the +12 volts on the signal line
without a problem, this is part of the RS-232 specification.)
