Section 5.1
Alternatively, the RS-485 port could be used for PC control.
).
2. Connect the RS-485 terminal block port on the first device to the RS-485
port on the second device, and so on for all devices. (Connect A to A, B to B,
and G to G.)
3. Set the machine number and termination as follows:
The first device is machine number 1 and the subsequent seven
devices are machine numbers 2 to 16 (see
Section 5.2.1
Terminate the first and last devices, that is, terminate machine
numbers 1 and 16. Ensure that all other devices are unterminated (see
