Serial Port Configurations
The meter has an option of one or two RS-232 ports, which can be arranged in a number
of configurations with an RS485 port. The two ports are called Modem and SCADA.
The possible options are listed in Table 3-2, which lines up with the order code options.

Table 3-2 Serial port options
Where only one RJ45 is fitted it is TB10 that is fitted. TB10 is the 1
st
RJ45 and TB9 is
the 2
nd
RJ45. The SCADA port is always RS232 in these options.
The connection on the label is indicated using a range of symbols that explain what the
connections are. For instance:
TB10
DUAL
RS232
RS232
corresponds with a Type 7 port. There is only one RJ45 (TB10), it is a dual connector
(2 serial ports on the one connector), power is supplied (
), and both ports are RS232
(the top port is the Modem port, the bottom is the SCADA port).
