6.2.3 Connecting and Controlling Multiple VS-88DTP Devices
You can daisy-chain up to 16
VS-88DTP
devices with operation via
RS-232 from a PC or serial controller (see
Figure 6
).
To daisy-chain up to 16 VS-88DTP devices:
1. Connect the RS-232-1 port
1
6.1
on the first
VS-88DTP
device to the PC
(see
Section
).
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 6.2.1
)
Terminate the first and last devices, that is, terminate machine
numbers 1 and 16. Ensure that all other devices are
unterminated (see
Section 6.2.2
)
