SERIAL/POWER Connector mates with Molex receptacle 0430251008 or similar with tin plated contacts.

Power Requirements

ConnectWare2 requires a minimum 1W DC power supply. It can be powered either by

  • USB @ 5V

  • 5V DC power supply on Molex connector pin 1 with pin 5 as ground reference

  • 5-24V DC power supply on Molex connector pin 6 with pin 5 as ground reference

Equipment Serial Interfaces

ConnectWare supports four different serial interfaces. A discovery routine is used by ConnectWare to detect the interface on first power up or after a factory reset. Standard baud rates between 9600 and 230400 are accepted. 115200 is recommended for normal telemetry. Higher baud rates can be achieved for large file transfer. See the API for more information.

The serial interface always uses no parity bits, 8 data bits, and 1 stop bit; N81.

USB Serial Interface

ConnectWare acts as a USB 2.0 device only. Use a USB Mini-B connector.

TIA/EIA RS-232 Serial Interface

ConnectWare2 supports standard RS-232 full duplex communication on Molex connector pins 7 and 8 with pin 5 used as a reference.

Absolute Maximum voltages are

Rx +/- 25V

TX +/- 13.2V

TIA/EIA RS-485 Serial Interface

ConnectWare2 supports standard RS-485 half duplex communication on Molex connector pins 2 and 3. RS-485 is a differential signal and requires no ground reference. ConnectWare is host. The pins 2 and 3 are internally terminated by 120Ω. A maximum of 230400 baud is possible.

Absolute Maximum voltages are +/- 14V

TIA/EIA RS-562 TTL Serial Interface

ConnectWare2 supports standard RS-562 full duplex communication on Molex connector pins 9 and 10 with pin 5 used as a reference. The interface is 3.3V and 5V compatible, line buffered and non-inverting.

Absolute Maximum voltages are

Input 5.5V

Output 3.3V

Logic Low 0.4V (16mA)

Logic High 2.4V (-16mA)

ConnectWare Reset

Molex pin 4 is an active low reset. Pulling this to ground reference pin 5 will perform the same actions as the reset buttons. This pin can be used to install a remote button or provide access to a control system.

Cloud Network Interfaces

Wireless

IEEE 802.11 a/b/g/n 2.4GHz Wi-Fi

AP-Mode for network configuration

Ethernet Option

10/100Mbit RJ-45

Recommend using CAT5E shielded cable.

Environmental

The top side of the PCB is conformally coated with silicone. The reset button is IP67 sealed.

The standard configurations without battery backup have a maximum operating temperature of 85°C.

With the battery backup option installed, the maximum operating temperature is 70°C.
