5 CIRCUIT DESCRIPTION AND SCHEMATIC DIAGRAMS T2130 MICROCOMPUTER The purpose of the microcomputer block is to run the programme properly. It consists of the following units: - an 8 bit Hitachi microprocessor U02 - an EPROM carrying the programme U01 - chip select circuit for the EPROM P01 and U13/2 - a watch dog & battery low detector U03. There are several options when configuring the microcomputer. The options are selectable in the jumper block area, ref. P01. - P01 selects where the microprocessor has to find the programme. I - Mode: E - Mode: Internal mode, (U02, pin 5 at +5V) This means that the programme must be masked and the processor is an HD6301Y type. The remaining jumpers P01/2, P01/3, and P01/4 have then no sense. External mode, (U02, pin 5 at 0V). The programme must reside in an EPROM (PROM) ref. U01. The processor type can either be HD6301Y or HD6303Y. - P01/2 sets the EPROM size - P01/3 & - P01/4 select in conjunction the address where the EPROM is to be seen for the microprocessor. 27C64 starts address E000 Hex: Figure 1: P01 connections for 27C64 27C128 starts address C000 Hex: Figure 2: P01 connections for 27C128 26043 1/9 PAGE 5-10 9315

The limits for the battery low detector are the following: - The PFO (pin 5) must be high (+5V) at 17.231 Volt or higher on the +18V. - The PFO must be low (0V) at 14.148 Volt or less on the +18V supply. - Watch dog. During normal operation the microprocessor resets the watch dog at known locations in the programme. If the microprocessor stays too long in an unintentional loop, without resetting the watch dog, the watch dog will activate the reset pin on the microprocessor. This may happen if the microprocessor is waiting for an external event which never occurs (failure in hardware), or noise has disturbed the programme execution. COMMUNICATION BUS DRIVER & RECEIVER (SP-BUS) The communication to the RE2100 is time multiplexed data bus. It is implemented with one 50 ohm coax cable terminated in each end and a driver and a receiver in each connected unit. The RE2100 is the master and a number of slaves may be connected to the SP-Bus. The driver and the receiver circuits are identical in each unit connected to the SP-Bus. The driver output is normally in high impedance state except when transmitting on the SP-Bus. The driver consists of two gates, U04/1 & U04/2 (74HC132), a transistor Q01 (BC558) for level shifting and two complementary output transistors Q02, Q03. The driver is connected to the microprocessor U02, pin 13 (Port 2, bit 4, transmit data), and pin 10 (port 2, bit 1, driver enable). The receiver consists of an op-amp, U06/1 (1458) which is configurated as a Schmitt Trigger and a gate U05/1 (74HC08) for level conditioning. The receiver is connected to the microprocessor U02, pin 12 (port 2, bit 3, receive data). 9737 PAGE 5-11
