CHAPTER 3: Installation
b) If the control device is connected directly to the Pow-R-Switch 1M’s Control
Port,
start your terminal-emulation software. Make sure that the
terminal-emulation software is set to the same data rate as the Switch
(see
Section 3.2
). The software should also be set to receive
8 data bits and no parity.
2. Once the connection has been made, send a few SPACE characters to
the Switch. (If the control device is a PC, do this by tapping the spacebar
on its keyboard several times.) When the spacebar is pressed, the LINK
indicator on the Pow-R-Switch 1M and on each Pow-R-Switch 1S should
flash briefly. If the LINK LED on any linked Switch module in the system
does not flash, check the following:
a) Make certain that all of the Switches are plugged into a working AC
outlet.
b) Make certain that the cables you have run between the Switches are
pinned straight-through and are firmly seated in the Switches’ Link
Ports.
c) Make certain that the data-rate settings of the Pow-R-Switch 1M (see
Section 3.2 ), the device connected to its Control Port, and all of the
Pow-R-Switches 1S match.
d) Make certain that the same address has not been assigned to two or
more Switches. Each module must have its own unique address (see
Section 3.1
).
