SmartPass® Integrated Reader 2450 MHz (High Voltage) System Guide
Operating Parameters
SmartPass readers maintain their operating parameters in battery-powered RAM
so that the parameters will be preserved after a power down sequence.
Output Circuits
Both the RS–232 and RS–422 configurations used by SmartPass have two output
circuits, output0 and output1. A typical installation may use one of the outputs to
control a gate or signal light, turning it on only when the host sends the turn on
command (command 620N).
Note:
Output1 is not available on Wiegand-configured SmartPass systems.
Power Fail
The system maintains a power fail flag. The host transmits display power fail bit
(command 520) to determine if a power down has occurred. This flag is cleared by
both reset reader (command 63) and reset power fail bit (command 65).
Program Download
The SmartPass applications software is stored into the reader flash memory by
program download. Program download is used to install program upgrades, add
features, and to recover from corrupted program data. The download mode supports
commands 90, 91, 96, 97, and 99.
Download Considerations
The following items should be considered when performing program download:
•
No tags are processed while in download mode
•
Only download commands are accepted while in download mode. The reader
responds to all other commands with an
Error
message
•
The reader will not accept any program data unless a successful erase of flash
memory has been performed before transmitting the data. Erasing the flash
memory typically takes 7 seconds
•
Exiting from download mode will re-execute startup. If the new software has been
loaded without errors, the reader will come up in data mode. If a flash checksum
error is detected, the reader will reenter download mode and transmit a sign-on
message with a software version of 0.00 and without a serial number
