5.2.3Connecting and Controlling Multiple VS-88DTP Devices

You can daisy-chain up to 16 VS-88DTPdevices 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 on the first VS-88DTPdevice to the PC (see

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 Section 5.2.2)
