Figure 2-1. RS-232 / RS-485 Option Board
You should install the option board in such a way the pin “1A” of “P11” is
aligned with pin “1A” of “J11” (on main board, refer to Figure 2-2).
When interfacing the meter to devices that do not have handshaking lines, i.e.
RTS/CTS, the S3-E Jumper should be installed. However, when interfacing to a PC,
the S3-E should be removed.
