Evaluation board specifications
Overview
The evaluation board has been designed to test and configure the Quanta product without any electronics development.
Standard connectors on the development board can be directly interfaced with your application (DB-9 for serial ports & CAN, RJ-45 for Ethernet, DIL connectors for SYNC In and SYNC Out).
The development kit includes the following accessories :
- USB cable (for PORT A connection)
- RJ-45 Ethernet cable
- An AC/DC power supply with international plugs to power the system
- UMCC to SMA cable adapter to quickly evaluate Quanta product directly inside your application

Power Supply Specifications
The DC 2.1 mm DC jack input supports a wide DC input voltage range [6 – 36V].
Alternatively, for current monitoring purpose, it’s possible to directly power on the Quanta system (without powering on the external components). In order to do so, the two jumpers between X6 and X7 should be defined according to the following rule :
- Jumpers between X6 and X7 on position 1 and 2: Internal power supply.
- Jumpers between X6 and X7 on position 3 and 4: External power supply. Apply Quanta power supply at X7 pin 1 or 2.

PORT A
By default, PORT A, SYNC IN A and SYNC OUT A are accessible through the USB micro connector available on the evaluation board (X11).
Alternatively, these signals can be directly accessed from the Quanta board using the dedicated DIL connector (X9).
When the jumpers are ON, the access is driven to the USB port. When the jumpers are removed, user can access to the direct Quanta signals with following pin definition.
Note
Unlike the other SYNC IN / OUT signals, the SYNC IN A and SYNC OUT A polarity is inverted when accessing to the direct TTL version, AND their corresponding USB behavior. Other ports have a reversed polarity in TTL and a normal polarity in the RS-232 DB9 connector.

PORT B
By default, PORT B, SYNC IN B and SYNC OUT B are accessible through the dedicated RS-232 DB-9 plug connector available on the evaluation board (X12).
Alternatively, these signals can be directly accessed from Quanta board using the dedicated DIL connector (X8).
When the jumpers are ON, the access is driven to the RS-232 port. The pin-out on the DB-9 plug is the following :
Quanta electrical specifications apply when accessing directly at the TTL outputs.
SYNC IN and SYNC OUT B have a reverse polarity at the TTL side and a normal polarity at RS-232 side.

Alternatively, these signals can be directly accessed from the Quanta board using the dedicated DIL connector (X16 and X18).
Quanta electrical specifications apply when accessing directly at the TTL outputs.
SYNC IN C and D have a reverse polarity at the TTL side and a normal polarity at RS-232 side.
