The MaxQ High Performance Orbital Shaker is equipped with an RS-232
Serial Communication Interface for the remote transmission of data. An
RJ-11 telephone style connector is located on the rear of the shaker. Refer
to Figure 1-14.
The data is "dumb terminal" formatted, which permits connecting to a
computer or a serial printer.
Three wires are used for the RS-232 interface:
1. Transmit data (/TXD) - pin 2
2. Receive data (/RXD) - pin 3
3. Signal ground (GND) - pin 7
The data format is:
Baud . . . . . . . 1200 (9600 baud w/ jumper at J2 on Main Control Board)
Data bits . . . . . . . .8 (7 bit ASCII with leading zero)
Start bits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .1
Stop bits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .1
