    3.2 Digital I/O 3.2.1 Digital Inputs The BL2600 has 16 digital inputs, DIN16–DIN31, each of which is protected over a range of –36 V to +36 V. The inputs are factory-configured to be pulled up to +5 V, but they can also be pulled up to +K or DCIN, or pulled down to 0 V in banks by changing a jumper as shown in Figure 7.

  • Page 92 The PD0, PD1, PE0, and PE2 signals are configured on the RabbitCore module, and not on the BL2600. These parallel-port bits are configured for Ethernet on RabbitCore modules with Ethernet and for output low on RabbitCore modules without Ethernet. The signals are not available on the BL2600 for customer use in applications.

    The input voltage range is from 9 V to 36 V. A switching power regulator is used to pro- vide +5 V for the BL2600 logic circuits. In turn, the regulated +5 V DC power supply is used to drive a regulated +3.3 V power supply and ±12 V power supplies used by the op- amps driving the digital outputs.

    PPENDIX ABBIT D.1 General RabbitNet Description RabbitNet is a high-speed synchronous protocol developed by Rabbit to connect periph- eral cards to a master and to allow them to communicate with each other. D.1.1 RabbitNet Connections All RabbitNet connections are made point to point. A RabbitNet master port can only be connected directly to a peripheral card, and the number of peripheral cards is limited by the number of available RabbitNet ports on the master.

    With this type of termination, the maximum frequency is limited by the round-trip delay time of the cable. Although a peripheral card could theoretically be up to 45 m (150 ft) from the master for a data rate of 1 MHz, Rabbit recommends a practical limit of 10 m (33 ft).

  • Page 106 RETURN VALUE The status byte from the previous command. -1 means that device information indicates the peripheral card is not connected to the master, and -2 means that the data length was greater than 15. SEE ALSO rn_write SBC BL2600...
  • Page 107 int rn_reset(int handle, int resettype); Sends a reset sequence to the specified peripheral card. The reset takes approximately 25 ms before the peripheral card will once again execute the application. Allow 1.5 seconds after the reset has completed before accessing the peripheral card. This function will check peripheral card information to determine that the peripheral card is connected to a master.

  • Page 109 int rn_rst_status(int handle, char *retdata); Reads the status of which reset occurred and whether any watchdogs are enabled. PARAMETERS handle is an address index to device information. Use rn_device() or rn_find() to establish the handle. retdata is a pointer to the return address of the communication byte. A set bit indicates which error occurred.
