Retrofit (Cable) Adapter Electrical Integration
Equipment Interface
The equipment can interface with the ConnectWare Cable Adapter using a field supplied standard DB9 Male cable connection.
Power Requirements
ConnectWare requires a minimum 1W DC power supply. It can be powered either by
5V DC power supply on pin 1 with pin 9 as ground reference
ConnectWare1 (950-000033)
5-12V DC power supply on pin 6 with pin 9 as ground reference
ConnectWare2 (950-000048)
5-24V DC power supply on pin 6 with pin 9 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.
Cable Adapters do not provide TIA/EIA RS-562 TTL Serial Interface wiring.
USB Serial Interface
ConnectWare acts as a USB 2.0 device only.
TIA/EIA RS-232 Serial Interface
ConnectWare2 supports standard RS-232 full duplex communication on pins 2 and 3 with pin 9 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 pins 4 and 5. RS-485 is a differential signal and requires no ground reference. ConnectWare is host. The pins 4 and 5 are internally terminated by 120Ω in the ConnectWare Module. A maximum of 230400 baud is possible.
Absolute Maximum voltages are +/- 14V
USB ID
ConnectWare is only implemented as a USB device. Do not place a jumper or connect to the 2-pin header on the back of the Cable Adapter. Doing so will cause the module not to bootup. USB Host mode is not implemented in firmware.
