Wiring the Series EHG SL10 Communications Ports
The graphic below reflects the control being held up-
right with the display facing the holder. As shown, there
are two jacks on the top of the communications module
(RJ45 like, with 4 pins on each) which can accommodate
either a four or six 6 pin modular plug. Communications
from a PC to any EHG SL10 controller on the network
can be established by connecting it to either of the two
available jacks. The other jack can then be connected to
other EHG SL10 controllers on the network (32 maxi-
mum).
Looking at either of the jacks as shown in the graphic
pin identification is from left to right.
- Left most pin, connects to ground terminal of converter
- Second pin from left, no connection
- Third pin from left, connects to converter A or T- / R-
- Right most pin connects to converter B or T+ / R+
