with the AMD Transmitter IC and provides notification to the Taxi TX chip of an incoming byte. 3. The serial differential signal drives the fiber optic drivers to send the data to up to two slave modules over a fiber optic cable. (The master has two channels allowing communication with two slave modules and two receivers, if selected. The slave modules only have one channel each.) The maximum distance between the master and slave modules is 1.4Km. a. If there is NO incoming signal to the master module (HE697FBX105) from the transmitter (HE697BEM713) : The master continues to maintain synchronization with the slave module(s) via a timing sync pulse sent by the AMD Taxi Transmitter IC. b. If there is an incoming signal to the master module (HE697FBX105) from the transmitter (HE697BEM713): A delay occurs within the master module during the conversion processes lasting 500ns. The delay only occurs when there is an initial incoming byte. Subsequent bits are not delayed, and thus, the delay is not cumulative. 3.1.3 HE697FBX100 Slave Module 1. The slave module (HE697FBX100) receives the incoming serial differential signal via the fiber optic receiver. (See Figure 3.2.) The data has been delayed due to travel time through the fiber optic cable. The delay is approximately 7ms. [through glass] for 1.4 Km. PAGE 17 20 NOV 1998 CH. 3: OPERATION 2. The serial differential signal is routed to the Taxi Rx1 IC and is converted into an 8-bit parallel format. The 8-bit parallel format is then sent to the FPGA where it is converted into digital logic. The digital logic is sent to the RS-422 Converter and is converted into RS-422 signals. The RS-422 signals exit the slave via the DB37 and are sent to the GE Fanuc Series 90-70 IC697BEM711 Receiver. a. If there is an incoming signal into the HE697FBX100 from HE697FBX105: Because of the various conversion processes within the slave module, there is a delay of 1ms. 3. The receiver responds to requests from the transmitter by sending data back to the slave and master modules in the reverse order of the processes described above. The total maximum delay of data from the HE697BEM713 Transmitter and the IC697BEM711 Receiver via fiber optic cable (1.4 Km.) is 17.ms (round trip delay). 3.1.4 Power 1. A supplied power cable is used to provide +5 VDC power from the PLC. . The interface consists of a 2-pin removable terminal connector and a DB9 Connector of the supplied power cable. 3.1.5 Fault Detection 1. In addition to LED indicators for status and error detection, an external fault circuit is also provided to send an input to a remote location to help notify the user of a fault. The external fault indicator port is a 3-pin removable terminal connector providing signals to allow fault detection.
