Basic System Communications
The Auto-Zone Basic Control System has only one communications loop. The Zone
Manager is always the master on the Basic System loop. You must be sure the Zone
Manager is connected, addressed correctly (see Figure 4-2), powered up, and functioning
if you are starting up or troubleshooting the communications loop. The optional
CommLink IV jumper switch must be set for single loop operation when used with the
Basic system. See Figure 4-5.
