IRIG-B
Time-Code Input
The SEL-734 accepts a demodulated IRIG-B time signal to synchronize the
internal clock with an external source. Two options for IRIG-B signal input
are given, but only one should be used at a time. IRIG-B (01 and 02) inputs or
an SEL communications processor via serial PORT 3 may be used (see
Table 10.6 and Figure 10.7). The available communications processors are the
SEL-2032, SEL-2030, SEL-2020, and the SEL-2100 Logic Processor (see
Table 2.3).
Ethernet Port
The SEL-734 can be ordered with an optional 10BASE-T Ethernet port
(PORT 1). You can connect to PORT 1 of the meter using a standard RJ-45
connector. The Ethernet port supports a total of three simultaneous sessions
(see Ethernet on page 10.4).
EIA-232 (Port 2)
PORT 2 is identical to PORT 3, except it does not support IRIG-B.
Optical Port
The front-panel optical port complies with the power requirements of C12.18
Protocol Specification for ANSI Type 2 Optical Ports. You can communicate
with the meter using an ANSI C12.18 optical probe.
SEL has tested a variety of optical probes for compatibility with the SEL-734.
Table 2.4, although not exhaustive, can be used as a guide for selecting
compatible probes.
Internal
Telephone Modem
The SEL-734 can be ordered with an optional communications card. PORT 4B
of this optional card is an internal telephone modem. Connect to the modem
using a standard telephone cable and RJ-11 jack. See Table 2.2 for required
hardware jumper position.
Sealing
Front-panel password protection seals the SEL-734 electronically. Any
operator can view meter data and settings, but a password is necessary to reset
or edit any field (see Front-Panel Security on page 11.3). Rear-panel
anti-tamper seals less than .095 inches in diameter (see Figure 1.2) provide
evidence of unauthorized access to the meter interior.
