7.4 Connecting the EXP-06E to a host
The connector – G, H, I connects a single EXP-06E to the host computer via RS-232C
format. Multiple EXP-06E communicates with host from connector – F, E via RS-485
format. But the EXP-06E chain must communicate with host through an
RS232/RS-485 converter.
7.4.1 Configuring the EXP-06E Jumpers
Configure EXP-06E jumpers JP4 & JP5 for the host communication format you are
using. For host communication using the RS-232C communication using the RS-485
communication protocol, set jumpers JP4 & JP5 to 1-2 position.
