3.0 INTERFACE PROTOCOLS
The GBA ST1C can communicate with a host (machine) via one of several base interface protocols.
These protocols are;
• NAMA MDB
• Pulse
• Parallel
• ccTalk
®
• Bi-directional serial protocol (“RS232”)
• SSP
• JVI/VCCS
Variants to some of these protocols are also available; please contact your regional office for
further details.
With the exception of MDB the GBA ST1C will be connected to the host machine using a cable
assembly terminated with a 20-way connector, as denoted in section 6.0 ELECTRICAL
CONNECTIONS.
For NAMA MDB, the interface cable terminates with a 6-way connector.
3.1 NAMA MDB
If the GBA ST1C is used in an MDB interface application, then it must be fitted with an optional 20
to 42 Volt power regulator and with opto-isolators on the communication lines, as required by the
NAMA MDB specification. This option must be specified when ordering the ST1C. An adaptor cable
is required to connect to a standard NAMA 6 pin connector.
Please contact Technical Support for details.
3.2 CCTALK
®
If the GBA ST1C is used in a ccTalk® interface application, an alternative 20 pin harness is available
if the host controller uses a single data line for communications both to and from the validator.
Part Number: ASY-W-10265.
Please contact Technical Support for details.
For further details relating to the operation of specific interfaces please refer to the Interface
Description Manual.
3.3 USB
The GBA ST1C can be offered with an optional USB interface. The USB mini-AB socket is fitted to
the side of the unit, next to the 20-way connector power plug.
The USB interface can be used to connect directly to a USB PC host, where it then acts as a USB /
serial comms port, and can be used to transmit the BSPC RS232, SSP and ccTalk protocols. The
GBA USB Driver will need to be installed; please contact your regional office for a copy, and specify
which version of Windows you are using.
