NOTE Using the configuration setting command to select standard or extended format.
UIC681 Programmer’s Manual • UDN PM063-U Rev. 4 (12H) – RS232 pass through enable COMMENT Enable RS232 data Pass Through (PT) function temporarily. FORMAT The command characters are followed by an ASCII ‘P’ to enable the RS232 pass through function. It is only valid in RS232 model. NOTE Once the pass through mode is enabled, UIC681 passes all data between COM1 and COM2 and do nothing.
UIC681 Programmer’s Manual UDN PM063-U Rev. 4 • p (70H) – Arm to Read (Used for Manufacturing Test Only) COMMENT 1.Clear read data buffers. 2.Transmit command acknowledgement (“^” 5EH). 3.Wait for card read. 4.If the card media is detected a "(" (28H) byte is sent, when media detect goes inactive a “)” (29H) byte is sent. This is similar to the 'P' command but send ‘(‘ at start of magnetic stripe card data and ‘)’ at end. • (1BH) – Abort Arm to Read COMMENT 1.Clear read data buffers. 2.

Command was received correctly. But could not be completed. No Magnetic Stripe Card Data. Command was received correctly. Communication Error. Command was not received correctly. Invalid Command or bad parameter. Power On report. Unavailable. Hardware not available to complete this request.
UIC681 Programmer’s Manual UDN PM063-U Rev. 4 Section5: Application Example The default setting of UIC681 reader, Self-ARM mode, is mainly to simplify the process for the host that doesn’t need to communicate to each other. In this situation, the UIC681 acts like a general magnetic stripe card reader whenever it senses the card, it will try to decode the card data automatically and send the decoded data to the host if the process is successful. Otherwise, no information is sent out.
UIC681 Programmer’s Manual UDN PM063-U Rev. 4 Host Polled Application Example A. UIC681 setting changed In this example, it assumes UIC681 is in factory default and the user would like to change it to protocol USI2 and Self-ARM disable. Initial State 1. Send the configuration command to set UIC681 to protocol 2. 2. Send the configuration command to set UIC681 to Self-ARM disable. Done This process should be done only once to set the UIC681 to the proper state.
