Verifying the RS-232 Communication

If your installation includes only one Hydran 201R Model i and if it communicates with the
host computer running the Hydran Host software, you must verify the RS-232 link. Proceed

1. Connect the Hydran 201Ci-1's RS-232 Computer Port connector (J10; item 7 in
Figure 3-7 on page 3-12) to your PC's RS-232 port. For wiring details, see Table
D-13 on page D-11. For USB users, connect the Hydran 201Ci-1's USB Computer
Port connector (J16; item 8 in Figure 3-7 on page 3-12).
