A step by step instruction manual for pairing the Spectrum Pro and the L100 can be found here: 80141506-001 Spectrum Pro and L100 Pairing Rev. B.pdf
ID TECH’sSmartPINL100encrypting PIN pad provides a compact, rugged, secure keypad interface for POS systems in which PIN and/or manual data-entry capability are required. As such, the L100 is a natural complement to ID TECH’s Spectrum Pro insert reader. Together, the Spectrum Pro and L100 provide an EMV Level 2 chip-and-PIN solution (suitable for use in kiosks and other unattended applications), meeting ADA, ANSI, PCI, and ISO standards for PIN Entry.
80141506-001 Spectrum Pro and L100 Pairing Rev. B.pdf describes the steps that must be undertaken in order to pair a SmartPIN L100 keypad with a Spectrum Pro card reader.
Theory of Operation:
The SmartPIN L100 is intended to offer a PCI-compliant solution for systems that require encryption of PIN data. To achieve this goal, the SmartPIN L100 must be paired with a compatible card reader. Once paired, the L100 encrypts keypad data at the point of entry, and no clear-text data is ever exchanged between the L100 and the connected reader. In order for pairing to occur, each device (PIN pad and reader) must be injected, ahead of time, with a so-called Pairing Key, representing a shared secret. This key is ultimately used to enable secure sharing of data between reader and PIN pad. The data shared includes both PAN (primary account number) data and PIN data. Cryptographic keys (and TDES encryption) are used to protect the PAN and PIN data at all times. Each unit (reader, and PIN pad) must be injected with the Pairing Key. This key represents a shared secret which unites the two devices such that they can communicate with each other using encrypted data (hence, the units are "paired"). Once the reader and the PIN pad are in the proper state (see discussion to follow), the pairing process itself is mostly automatic and out of the operator's control. From a high level, it involves the following steps:
1. Both units (Spectrum Pro and L100) need to have been injected with Pairing Keys.
2. The SmartPIN L100 needs to be in Removal Detection Mode in order to undergo the pairing process.
3. With the units connected to each other, a pairing command (76 46 38 00 00) needs to be sent to the Spectrum Pro. The Spectrum Pro will then automatically carry out all necessary communications with the PIN pad, and pairing will be complete. You will be able to verify this by (for example) conducting an MSR read (Start MSR command) followed by a Get PIN from MSR, using the Universal Demo program; the latter will result in a PIN prompt from the L100, and then (after a PIN is entered manually) the command will allow the L100 to return an encrypted PIN block.
Prerequisites:
- A SmartPIN L100, injected with Pairing Key
- A Spectrum Pro, injected with Pairing Key
- RJ-11 to Serial cable, to connect Spectrum Pro's RJ-jack to the L100 serial port,
- A 5-volt DC power source for the L100
- USB cable to connect Spectrum Pro to host,
- Two large steel binder clips, C-clamps, or other fixture(s) to hold the L100's tamper buttons down
- One large steel clip or C-clamp to depress the Spectrum Pro's removal-detection buttons
Host software that can open a connection with Spectrum Pro and send firmware commands (e.g.,ID TECH Universal SDK Demo app)
