OLLERS
Multiple baud rates are supported for the diverse mix of communications equipment available for
the SE 6000 system. The baud rate is set by changing the HOSTBAUD parameter in the
$DATAPATH/NPOLLER.x file where x is the associated poller number. The baud rate is entered
during installation or changed as needed by the system administrator; operator action is not
required. The baud rate options are:
Parameter missing — HOSTBAUD defaults to 4 (9600 bps)
HOSTBAUD=4 — 9600 bps
HOSTBAUD=3 — 4800 bps
HOSTBAUD=2 — 2400 bps
HOSTBAUD=1 — 1200 bps
HOSTBAUD=0 — 300 bps

OTE
1. The baud rate set applies to all devices controlled by the poller.
2. Though functional, the 300 bps baud rate (HOSTBAUD=0) is not recommended for the 800-
series devices. The amount of data downloaded to intelligent ACUs significantly impacts
overall system performance when inefficient communication facilities are used.
3. On 708P ACUs, the host port speed on the device is set with dipswitches. Both the device
and the poller must be set for the same speed.

ESET
The normal operation of a REX switch is to shunt an associated door switch when opening the door
from the nonreader controlled side, or —and in addition— to automatically unlock the door. Once
the door switch is toggled, a DOOR HELD OPEN message is generated if the door is not closed
within the time defined in the door switch point record.
Designed for high-traffic areas, this feature enhances the REX / Door switch functionality by
providing a method to reset the door switch timer while the door is being held open. While
employees continue to present valid keys and to pass through the door (causing the REX point
to continually change state), the door switch timer is reset each time to the number of seconds in
the door switch point record, thus preventing a DOOR HELD OPEN message from being
generated. (The message is generated if the time between key presentation exceeds the time
value in the record.)
