- Page 3 TC8916 is transparent to all data sent in either direction. The MAIN port on the TC8916 receives a broadcast message from the main controller via Port 1 and simultaneously broadcasts the message out through all additional ports (Ports 2 through 8, 16, or up to 24 - depending on the model).

- Page 8 Pins 3 and 4 are balanced output pins. Pin 3 is the positive output (RxData +) while pin 4 is the negative (RxData -). Either pin 6 or pin 1 can be Signal Ground. Only RS-422 Async communications can be used with the TC8916 due to the limited number of pins on the RJ-11 connector.
- Page 9 The user's device can be a DCE or DTE device (which may have a DB25 male connector). The following illustrations depict the RS-232/TTL & RS-422 wiring diagrams for constructing an RJ-11 to DB25 Female adapter cable. MNL-89160-05-03 - 9 -...

- Page 11 The TC8916 has been pretested and switches have been set per factory specifications. Channel 1 is used for the RS-232 or RS-422 signal input to the TC8916 which will be broadcasted to the user's devices. The remaining channels are for electrical signal connections to the user's poll-type devices.
- Page 12 Anti-streaming is used to eliminate a 'high' signal lockup of the user's device(s). When the Anti-Streaming function is enabled, the TC8916 can detect a 'high' signal over a fixed time duration (set by the internal SW3 timer DIP switches) and will automatically reset that channel to a 'low' signal when "jabbering" is detected.
- Page 13 1. Apply the power by plugging the power into any power terminal block connector on the rear panel. The power source can be from a power adapter or from a power card (installed either on the left or right side of the rack).
- Page 14 For the additional (Optional) expansion cards, the Card ID (or address) must be set properly before using the TC8916. Set the Card ID for each card according to the example below. The Card ID of each additional expansion card must be set in a binary sequence.
- Page 15 The RJ-11 cable connectors and DB25 connector are frequently the source of various problems. Check out the connectors, cable, and pin connections first. Once installation of the TC8916 is complete, it is a good idea to perform a Local Loopback test to verify that the TC8916 is working properly.
