To add additional Relays, you must “multi-drop” them off a single bus line running from the unlabeled port on the Base station. See the section below for cabling requirements and pin-outs. It is very important to follow the pin-out directions carefully and to use the suggested cable type. The majority of problems we see are the result of incorrect wiring.
Each Relay requires it’s own power supply. There is no serial parameter setup required on a Relay as it is transmitting only to the Base station and not directly to a serial port.
Routing the Wiring
The below diagram illustrates the RIGHT way to route your wiring and which units should be terminated. Notice this is the classical bus interface where the Base and Relays are connected to a “one-cable bus”. The bottom of the Y-Cables is connected into the unterminated base or relay(s). Notices that the two end units are terminated; the units in the middle are unterminated, including the Base in this example. Keep in mind that the maximum total cable length from end-to-end is 4000' for good quality twisted pair wire.
Correct Routing for Wiring
The next diagram illustrates the WRONG way to route your wiring and use the Y-cables. Sometimes people try to route everything through a panel or wiring closet – this will not work properly; it will generate excessive data noise and drag down the responsiveness of the Base and application. (With too much noise, the Base will stop working and issue a “Base Station Reinitalized” message to the terminals. If used, such a radial interface as below might appear to work most of the time, but it would be very sluggish and crash several times per day. Terminating or not terminating will be of no help. Do Not cable as shown below:
