USB-Link LED Descriptions

RS-485 - Indicates communication activity between the

USB-Link and the controller(s) that the USB-Link

is connected to. When both the “T” and “R” LEDs

are ﬂ ashing, data is being exchanged.

USB - Indicates communication activity between the

USB-Link and the computer that the USB-Link

only when data is sent from Prism II to the USB-

Link via USB.

USB-Link Communication Settings

The communication switch for stand alone or network mode is

found to the left of the LEDs. See Figure 3 above. To set the

communication switch, insert a pen tip to move the switch up

or down.

NOTE: Whenever you change the communication setting

on the USB-Link, you must cycle the power to the

USB-Link by disconnecting and reconnecting the

USB power supply cable.

Stand Alone - No MiniLink or CommLink - The slide switch

on the USB-Link should be set to “Stand Alone” when you

are trying to talk to a stand alone controller or multiple con-

trollers on a loop without a CommLink or a MiniLink wired

to the communications loop.

Network - MiniLink or CommLink connection - The slide

switch on the USB-Link should be set to “Network” any time

there is a CommLink or MiniLink wired to the communications

loop.
