Design the serial connections between the module and the device(s)
it will connect to as directed in paragraph 2.6. Note that standard
RS-232 cables may not work and you may need to design a special
cable depending upon the connections to your Modbus device(s). If
you are using RS-422 or RS-485 signals, you will have to change the
internal signal selection jumpers as directed in paragraph 2.7.
4.
Connect the AC adapter to the 8099 and to the AC power. Turn the
unit on and verify that it passes its selftest routine and that the PWR,
RDY and LNK LEDs are on. Use ICS’s VXI-11 Keyboard Program
(VXI11_kybd) to verify communication with the Modbus device(s).
5.
If you are going to rack mount the 8099, turn the unit off and discon-
nect all cables from the unit. Follow the instructions in Section 2.9
to install the 8099 in the rack mounting kit.
