2.11 DATALINK CONNECTIONS TO THE CONTROLLER
Figure 2-32 illustrates a Datalink network daisy-chain installation for controllers with the standard
rear terminal board. Four of the cable leads are connected to TB1 screw lugs 19 through 22, and
the shield is connected to a #6 backpanel screw. The installation is terminated with a Comm ITB.
Terminal board wire connections for the controller and Comm ITB are defined in Table 1 of the illus-
tration.
Figure 2-37 illustrates a Datalink network daisy-chain installation for controllers with the cord set
connector board. The first Comm ITB in the illustration provides cable conversion from the stand-
ard shielded four lead cable to the modular cable. When a Comm ITB is used for cable conver-
sion, the two load resistors R1 and R2 are removed from the board. The modular cables are then
daisy-chained from J11 (OUT) of one controller to J10 (IN) of the next controller. The network is
terminated with a Comm ITB, which has the two load resistors R1 and R2.
2.12 MICROLINK CONNECTIONS TO THE CONTROLLER
Installation information for the MicroLink network and MicroLink-Datalink gateway is provided in In-
struction Bulletin 53MC9011, Revision 2, MicroLink.
