SERIAL:
Bi-directional
serial data connections of the removable terminal block. The 7707MTA-HD
accommodates one channel of RS-422, RS-232, or RS-485 serial data. Data input
connections are labeled DI, while data output connections are labeled DO. The card must
be configured for use with RS-422, RS-232, or RS-485, as described in section 3.4. Serial
data connections are assigned per the data type selected. RS-422 and RS-232 signals are
connected as follows:
RS-422 -
Connect positive and negative RS-422 input and output signals to the
corresponding positive and negative terminals of the 7707MTA-HD. Bi-directional data will
be communicated to and from the companion 7707MRA-HD.
RS-232 -
Connect each RS-232 input data signal to the negative DI terminal (DI-) of the
7707MTA-HD. The companion 7707MRA-HD will output each signal on the corresponding
negative DO terminal (DO-). Likewise, serial data signals applied to the companion
7707MRA-HD will be output from the 7707MTA-HD.
RS-485 -
Operation with RS-485 requires that DI and DO terminals be connected together.
The DI+ terminal should be connected to the DO+ terminal, and the DI- terminal should be
connected to the DO- terminal. Connect positive and negative RS-485 signals to the
corresponding positive and negative terminals of the 7707MTA-HD.
See section 3.4 for serial data specifications.
See section 4.2.10 to 4.2.15 for serial data configuration instructions.
GPI:
General Purpose Input connections of the removable terminal block. The General Purpose
Input is an active-low, opto-isolated connection activated by connection to the ground pin.
GPO:
The General Purpose Output is dry-contact relay closure. The A and B terminals are
jumper selectable as normally open, or normally closed, via a jumper on the I/O board.
See section 3.5 for GPIO specifications.

2.1.2.1.
Single Fiber Versions
FIBER I/O:
This is the optical input/output of the single-fiber 7707MTA-HD-W module. The connector
is a female SC/PC (shown), ST/PC, or FC/PC connector as specified at the time of
purchase. This input/output should be connected to the FIBER I/O connector of a
companion single-fiber 7707MRA-HD-W module with a suitable fiber optic cable.
The 7707MTA-HD-W is designed to work with single-mode fiber optic cable. The
7707MTA15-HD-W transmits and receives on 1550nm and 1310nm wavelengths
respectively.
