Using the COM Connectors
Ethernet communications, event input, remote on, start record input, and status signals are
supported via the COM connectors. These connectors are functionally identical and are
compatible with all SLICE PRO and TDAS COM connectors.
Communications are supported via an Ethernet REC cable (P/N 10700-0015x) using either
COM port. SLICE PRO, TDAS G5 and TDAS PRO equipment can be daisy-chained via the
COM connector using an RDC cable (P/N 10700-0014x) and following the interconnect
protocol:
1. The Ethernet cable (P/N 10700-0015x) is connected to the first unit using either COM
port.
2. The RDC cable ( M ASTER) is connected to the first unit using the open COM port.
3. The RDC cable ( S LAVE) from step 2 is connected to the second unit using either COM
port.
Steps 2 and 3 are repeated for additional units. Each unit in the middle of the chain must
contain one MASTER and one SLAVE connection. Up to 7 SLICE PRO, TDAS G5 or TDAS
PRO systems can be connected in this manner.
Using the Event Input
The SLICE PRO Ethernet Controller contains an isolated, ESD-protected,
contact-closure event input. The event input is available through both of
the 19-pin COM connectors. SLICE PRO LAB also includes a dedicated
event input connector. This input provides a way to use a contact-closure
switch in harsh or noisy environments without negatively affecting the data acquisition system.
A software trigger can also be used
—please see your software manual for information on
how to set a software level trigger.
The event input may be used in either of two ways.
•
In Circular Buffer mode, this input triggers data collection and marks zero time (T=0).
•
In Recorder mode, this input is used to mark T=0 only.
Simple Contact Closure
Self-powered with a current conducting capability of at least 5 mA
Polarity must be observed if applying an event signal via a
semiconductor device such as a transistor or FET
1000 V isolation
