Technical Specification The Geo line of bill acceptors accepts bank notes through 85 mm in width. The Geo SL comes pre- programmed, per customer specification, from the factory or can be reconfigured by customers utilizing the gFlash program for PC’s. Software updates can also be uploaded into the Geo via a PC enabled with the gFlash program.
Refer to the top mounted diagnostic LED on the Geo. If the LED is flashing, refer to the diagnostic card on the top of the unit to detail the possible problem. If you cannot rectify a problem on site, please contact your local MEI authorized service center or MEI.
Interface Descriptions Field Configurable Interface Settings: Interface Switching Mode This feature is enabled only when the GeoSL is set to one of the following interfaces: • Pulse • Parallel • Parallel binary • ccTalk (ccTalk requires that a ccTalk interface module (VT-PCBA12) be installed in the GeoSL) 1.
Parallel Interface: The Parallel interface provides specific output lines for designating which note has been validated. This interface also provides for escrow and alarm functions. Outputs are open collector and can sink up to 100mA at up to 24VDC. Inputs are TTL Default setting for the outputs is active low, it is possible to set them to operate active high with the mFlash configuration software.
Escrow: This mode allows 'on the fly' enabling and disabling of each denomination accepted by the bill acceptor. The enable and escrow lines are used in combination to allow this. The procedure for accept and return is as follows; 1. Enable line and Escrow line are held low (0V) by the host machine. On insertion of a valid bill, the bill acceptor outputs the relevant pulse and holds the bill.
Parallel Binary Interface: This interface utilizes the first four of the Parallel outputs. Instead of a single pulse on each line to denote a particular denomination as in the Parallel interface, the Parallel Binary credit information is sent as a low going output pulse (100mS) which is sent simultaneously on the required lines.

"True" RS232 The ‘True’ RS232 interface provides for comms. between a Host (PC) and Slave (acceptor). This interface operates at ‘True’ RS232 levels and allows direct connection between the acceptor and PC comm. port without the need for special interface harness/loom. 9600 bps, 1 start bit, 1 stop bit, 7 data bit format.
TTL RS232 The TTL RS232 interface operates at TTL levels, 9600 bps, 1 start bit, 1 stop bit and 7 data bits. IF Cable: VA-WIRA06 Input Voltage: +12 VDC Pin1: +12 VDC Pin 2: Ground/Earth (power) Pin14: TTL RXD (receive data to acceptor) Pin 15: Common Pin 16: TTL TXD (transmit data from acceptor) For complete technical detail on the RS232 interface, refer to manual VTIRS-x...
Serial Interface: The Serial interface is a MEI compatible, bi-directional interface. It operates at 600 bps, 1 start bit, 1 stop bit and 8 data bits.
