Rear Panel Features
The functions of these connectors are described in the following table:
12V DC
This jack socket is used to connect the unit to the power supply
using 12V DC mains adapter.
SERIAL 0
This 25-way D socket provides a synchronous/asynchronous
RS2322 serial port which may be used to connect the unit to a
compatible serial device. The unit is supplied with a suitable 2
metre serial cable. To comply with EMC requirements it should
not be used with a longer cable.
SERIAL 1
On the TA2020B this 9-way D socket provides an asynchronous
RS2322 serial port which may be used to connect the unit to a
compatible serial device. The unit is supplied with a suitable 2
metre serial cable. To comply with EMC requirements it should
not be used with a longer cable.
On the IR2110B, this port is disabled.
LAN
On the IR2110B this socket is used to connect the unit to a
10/100-BaseT LAN using the 2-metre STP (Shielded Twisted
Pair) cable supplied or a suitable alternative. This port is auto-
sensing for speed and wiring (straight-through or cross-over). To
comply with EMC requirements it should not be used with non-
STP cable.
ISDN
This socket is used to connect the unit to an ISDN line.
Reset switch
This is located on the underside of the unit near the front. Pressing the switch gently with
the tip of a pen or other suitable implement will generate a hardware reset.
