RouterBOARD 200 Series User's Manual
Input/Output Ports
LAN1 Port with PoE
This Fast Ethernet port is recognized as first LAN interface in most OSs. If is fully compatible with
IEEE802.3af Power over Ethernet standard and accepts 48V input voltage. To use PoE power option, both
JP4 and JP5
must
be switched to the
3-2
position.
The RouterBOARD 51 power injector may be used to power the board with up to 150m (492 ft) long
Ethernet cable.
See
Connector Index
for pinout of the standard cable required for PoE. All cables made to EIA/TIA
568A/B cable specifications will work correctly with PoE. Note that this is a standard host Ethernet port
and if it is required to connect to another host, then a cross-over cable should be used.
Note
that the
IEEE Ethernet standard requires a minimum 2m long cable (6.5 foot).
LAN2 Port (RouterBOARD 230 only)
The second Fast Ethernet port does not have PoE power option and thus is used only as a separate
Ethernet port. Note that this is a standard host Ethernet port and if it is required to connect to another
host, then a cross-over cable should be used.
Note
that the IEEE Ethernet standard requires a minimum
2m long cable (6.5 foot).
USB Port (RouterBOARD 230 only)
The USB port is fully compliant with USB 1.0 standard. Booting from USB floppies, USB FlashCards or
other USB drives currently is
not
supported.
GPIO Header
General Purpose Input/Output (GPIO) header is a set of six user programmable input and/or output
interfaces. Sample code is given in the
RouterBOARD 200 SDK
.
ACCESS.bus
ACCESS.bus is a two-wire synchronous serial interface compatible with Intel's SMBus and Philips' I
2
O. The
ACCESS.bus allows bidirectional communication with a wide range of low-cost devices and memories.
Sample code is given in the
RouterBOARD 200 SDK
.
Intrusion Detection – J16
This is programmable jumper that may be found useful for intrusion detection, or, for example, as a serial
console reset switch. Sample code is given in the
RouterBOARD 200 SDK
.
LCD Out Header
LCD output header is used to connect parallel LCD devices. Supports LCDs sold by MikroTik. Sample code
is given in the
RouterBOARD 200 SDK
.
LPC Connector
Low Pin Count (LPC) interface is based on Intel Low Pin Count Interface specification, revision 1.0. It
provides all required signals as well as two optional.
DB9 Serial Port
The RS232C standard male DB9 asynchronous serial port may be used for initial configuration. TxD (pin
3) of this port has -12V DC power when idle, and DTR (pin 4) of this port always has +12V DC power (all
voltages given when not loaded).
