Host Connector
.
The host connector is a 28-pin circular twist-lock
connector as shown in figure 1-5
series) that mates with a supplied 28-pin socket
connector (P/N 98-200001-01). It allows the
scanner to be connected to a host, a concentra-
tor, or other communications device such as a
PLC (programmable logic controller), a monitor,
a PC, a relay, a diverter, an alarm, etc.
Pins 6, 8, and 25 (table 1-3) can be used to
drive a small relay to operate an alarm, diverter, etc. A pulse will be sent to
pin 8 at the occurance of any noread. Outputs to pins 6 and 25 are pro-
grammable (see "Relay Settings" on page
age level ("Output Polarity" on page
Pulse Width" on page 2-33) for all three pins (6, 8, and 25).

a. See your multidrop manual for multidrop cabling and termination requirements.
b. The default communications mode does not support pin 4 (RTS). If RTS and CTS are not
required by the host port, pins 4 and 5 should not be wired as the results will be unpredictable.
c. Source or sink 4 mA.
d. Bringing pin 28 to ground resets the CPU, clears all buffers, and restores all parameters that
have been saved to nonvolatile memory.
