Use standard CAT5 cables for Ethernet connections. Use control wire as applicable for
local electrical codes for connecting the 24V (AC or DC) power supply.
Note that in addition to connecting power supply common to a GND terminal, you
must also connect a GND terminal to earth ground in order to ensure proper ESD
protection.
BB2-7010-xx-232: The standard BB2-7010 Modbus RTU port uses RS-485. The
RS-232 version replaces the RS-485 transceiver with an RS-232 transceiver. The
NET+/NET- terminals are replaced by TXD and RXD on the RS-232 version. TXD is
data out from the BB2-7010, and RXD is data in to the gateway. Hardware handshake
is not supported.
A.2 Front Panel LED Indicators
Power-up LED behavior: All LEDs on front panel will turn on yellow or red for half a
second, then all will turn on green for half a second. Then they will proceed to indicate
as normally defined for the indicators.
The LED indicators behave as follows. Normally the reply/request LEDs reflect Modbus
RTU activity. If the gateway is being used only for Modbus TCP (as SNMP gateway),
then the same LEDs reflect TCP bahavior instead. The LEDs do not attempt to reflect
both RTU and TCP activity since that would get confusing. If both RTU and TCP are
used, the request/reply LEDs reflect RTU traffic while the Ethernet activity LED will
indicate TCP traffic. To see TCP errors, one needs to look at the Errors page in the web
UI.
DEV DATA
Flashes yellow each time a request is sent when operating as
Modbus Master, or each time a request is received when
operating as Modbus Slave.
DEV STATUS
Operating as Modbus Master, flashes green each time a good
response is received, or red when an error code is received,
the request times out, or there is a flaw in the response such
as CRC error.
