1.Introduction
The ACC-110A is a low cost and high performance long range 125kHz proximity card reader for reading ID code from uem4100 compatible read-only tags.
The ACC-110A is ideal for installations incorporating parking control, personal identification, access control and through-wall, hands-free, logistic etc. and long read range applications.
The ACC-110A reader packages all the electronics in one rugged, weatherized epoxy resin enclosure designed to withstand harsh environments as well as provide a high degree of vandal resistance for reliable performance anywhere, attractive and easy-to-install indoor/outdoor.

Calculation of ASCII Check sum:
Suppose a card ID=12, 34, 56, 78, 90 Adding in hex gives:
12
34
56 Thus 2+4+6+8=14(20 decimal). The 1 is carried. The 4 is the low sum.
78 and 1+3+5+7+9+carry (+1) =1A (26 decimal). The 1 is discarded. The A is
90 the high sum. The gives A4.

5. Operation
Proximity cards are presented to the front of the ACC-110A. The beeper sounds when the proximity cards is read and the message is transmitter the Host computer or interface panes.
Trouble Shooting:
When powered up,the ACC-110A take a self-test to ensure the best reading performance with the buzzer beeping continually. when the self-test ends, the buzzer will give out a bug beep and the ACC-110A enter the normal working mode. If the buzzer continue beeping without stop for a long time, please turn off the power and check out environment and power supply to ensure locating the ACC-110A in a good working condition. In case of problems the following procedure should be followed:
Failure to finish self-test with the buzzer beeping continually or with a short reading distance
1. Turn off the power to the ACC-110A
2. Check the power input connections making sure that they are not reversed
3. Check the power supply complying with specification
4. If the supply has a current limit , set this to 350mA
5. Make sure to install the ACC-110A in a environment without large area conductors nearby a mounting on a conductive surface. In self-test state , do not apply any tags in ACC-110A’s functional area
6. Try to change the installment of the ideaReader5100 to another place to check if the trouble still exists
Radio Frequency Interference
Motors and electronic devices generate RF noise that may interfere with the reception of the signal from a transponder. The affect of RF noise is typically a reduction of read range. The ACC-110A is susceptible to RF interference, as are all devices that receive RF signals. The read range is affected by the amount of interference(noise) in the area. Common sources of RF interference are power supplies, electrical and electronic equipment, some types of lighting ,computers and monitors, motors and generators. Moving the reader to a location known to be free of interference and testing read range there will help to isolate RF interference as a factor in low read range situations.
The ACC-110A should not be mounted within six feet of any monitors(VDTs or CRTs)because the scan frequencies of most monitors include frequencies that may interfere with signal received from the access control cards.
Mounting:
Mount on non-metallic surfaces for optimal read range performance.
Diagnostics:
On reader power-up, an internal self-test routine checks and verifies the setup configuration, determines the internal or external control of the beeper, and initializes the reader’s operation.
Indication:
when a proximity card is presented to the reader, the beeper sounds.
Indoor/outdoor design:
The ACC-110Asealed in a rugged, weatherized epoxy resin enclosure designed to withstand harsh environments as well as provide a high degree of vandal resistance for reliable performance anywhere.
Power supply:
The ACC-110A reader can be operated at 12 VDC linear power. If the reader power overrun 15VDC is applied,can't be operated, or If AC power is applied,circuit damage can result,12VDC linear power supplies are recommended.
Noise from devices such as switching power supplies, computer monitors, and arc welders can reduce the read range or make the unit inoperable. Keep these devices at least 10 ft away from the reader, With the ACC-110A and power supply wired together, apply power to the reader.
CAUTION:
12VDC linear power supplies are recommended. Failure to provide an adequate current capacity power supply will result in reduced read range or circuit damage.
Read range will be reduced if located on metal surfaces or in the vicinity of metal objects or metal is installed nearby or the affect of switching power supplies, computer monitors, electrical and electronic equipment, motors and generators etc.
