• Table 6-8, ”Spotty Pattern or Low Handshake Counts
Note: The troubleshooting procedures in this chapter test only the Amtech
® IT2200
Reader System with Multimode Capability. For other problems, such as host computer
or power supply failure, refer to the manufacturer’s documentation for the correct
troubleshooting procedures.
Table 6-3 Failure Indicated by Host Software Diagnostics
Failed Test Action
Boot Flash Boot sector of flash memory failed. Replace reader logic card.
Application
Flash
Application sector of flash memory failed. Replace reader logic
card.
TDM Incorrect TDM settings.
RFI RAM RFI RAM failed. Replace reader logic card.
Processor
RAM
Processor RAM failed. Replace reader logic card.
Battery
Status
Battery might be low or dead. Check that battery jumper J8 is
shorted (see Figure 6-5). If the jumper is shorted, the battery
failed. Replace the reader logic card.
Serial
EEPROM
Serial EEPROM might have failed. Save configuration to
nonvolatile RAM. If the problem persists, the serial EEPROM
failed. Replace the reader logic card.
Real Time
Clock
Clock or battery might have failed. Check that battery jumper J8 is
shorted (see Figure 6-5). If the jumper is shorted, the clock failed.
Replace the reader logic card.
RF Data
EEPROM
Data cable, RF module data EEPROM, or RF module power
supply failed. Open the RF module and check for 19 to 28 VAC or
16 to 28 VDC at terminals A and C. If the voltage setting meets
your requirements, test the data cable using a loopback
connector. If the cable is good, the RF module data EEPROM
failed. Replace the RF module.
RF Serial
Link
Data cable, RF module reader port, or RF module power supply
failed. Open the RF module and check for 19 to 28 VAC or 16 to
28 VDC at terminals A and C. If the voltage setting meets your
requirement, test the data cable using a loopback connector. If
the cable is good, the RF module reader port failed. Replace the
RF module.
RF PLL
Lock
Data cable, RF module PLL lock, or RF module power supply
failed. Open the RF module and check for 19 to 28 VAC or 16 to
28 VDC at terminals A and C. If the voltage setting meets your
requirements, test the data cable using a loopback connector. If
the cable is good, the RF module PLL lock failed. Replace the RF
module.
Frequency
Program
Mode
Check that the frequency enable switch SW1 on the reader logic
card is set to diagnostic or normal as needed (see Figure 6-6).
