Page 18: Digital I/O
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 19: Pwm Outputs
The actual switching threshold is approximately 1.40 V. Anything below this value is a logic 0, Normal Switching Levels and anything above is a logic 1 The digital inputs Spikes +40 V are each fully protected over a range of -36 V to Spikes +36 V +36 V, and can handle short spikes of ±40 V. -
Page 20: High-Current Digital Outputs
3.2.3 High-Current Digital Outputs The BL2600 has four high-current digital outputs, HOUT0–HOUT3, which can each sink or source up to 2 A. Figure 9 shows a wiring diagram for using the digital outputs in either a sinking or a souring configuration. +HKx 27 kW 10 kW... - Page 21 Each high-current output has its own +K supply. When wiring the high-current outputs, keep the distance to the power supply as short as possible. CAUTION: If you are using a BL2600 with the IDC header connectors, beware that an individual IDC header pin can only handle up to 1 A. Since the same high-current outputs are available on opposite pairs of IDC header connectors, you can still use the 2 A sinking or sourcing capability of the BL2600 by wiring all your connections, including the ground, in parallel to the opposite pairs (see Figure 10 for an example).
-
Page 22: Configurable I/O
3.2.4 Configurable I/O The BL2600 has 16 configurable I/O that may be configured individually in software as either digital inputs or as sinking digital outputs. By default, a configurable I/O channel is a digital input, but may be set as a sinking digital output by using the digOutConfig function call. - Page 23 When you use the software function call to read the configurable I/O, DIO00– digIn DIO15 are considered to be digital input channels 00–15. Note that the function digIn call can also read these channels if they are set to be sinking digital outputs. Table 2 lists the banks of digital inputs and summarizes the jumper settings.

Page 24: Serial Communication
3.3 Serial Communication The BL2600 has three serial communication ports, which can be configured as one RS-232 serial channel (with RTS/CTS) and one RS-232 (3-wire) channel or one RS-485 channel, or as three RS-232 (3-wire) channels, or as two RS-232 (3-wire) channels and one RS-485 channel by using the software function call. - Page 25 The BL2600 can be used in an RS-485 multidrop network. Connect the 485+ to 485+ and 485– to 485– using single twisted-pair wires (nonstranded, tinned) as shown in Figure 13. Note that a common ground is recommended. Figure 13.

Page 26: Programming Port
For best performance, the bias and termination resistors in a multidrop network should only be enabled on both end nodes of the network. Disable the termination and bias resis- tors on any intervening BL2600 units in the network by removing both jumpers from header JP6. -
Page 27: Ethernet Port
3.3.4 Ethernet Port Figure 15 shows the pinout for the Ethernet port (J2 on the BL2600 module). Note that there are two standards for numbering the pins on this connector—the convention used here, and numbering in reverse to that shown. Regardless of the numbering convention followed, the pin positions relative to the spring tab position (located at the bottom of the RJ-45 jack in Figure 15) are always absolute, and the RJ-45 connector will work properly with off-the-shelf Ethernet cables. -

Page 33: Programming Cable
3.7 Programming Cable The programming cable has a level converter board in the middle of the cable since the BL2600 programming port supports CMOS logic levels, and not the higher voltage RS-232 levels that are used by PC serial ports. When the programming cable is connected, Dynamic C running on the PC can hard-reset the BL2600 and cold-boot it. -

Page 89: Appendix D. Rabbitnet
ABBIT D.1 General RabbitNet Description RabbitNet is a high-speed synchronous protocol developed by Z-World to connect periph- eral cards to a master and to allow them to communicate with each other. All RabbitNet connections are made point to point, and until a port-expansion method is available, 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. - Page 90 Signal = 0.1" headers or sockets Power = 0.156" friction-lock connectors RabbitNet = RJ-45 connector Visit Z-World’s Web site for up-to-date information about additional cards and features as they become available. The Web site also has the latest revision of this user’s manual. Wolf (BL2600)

Page 91: Physical Implementation
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, Z-World recommends a practical limit of 10 m (33 ft). -
Page 92: Function Calls
D.3 Function Calls The function calls described in this section are used with all RabbitNet peripheral cards, and are available in the library in the Dynamic C folder. RNET.LIB RABBITNET int rn_init(char portflag, char servicetype); Resets, initializes, or disables a specified RabbitNet port on the master single-board computer. During initialization, the network is enumerated and relevant tables are filled in. - Page 93 int rn_find(rn_search *srch); Locates the first active device that matches the search criteria. PARAMETER srch is the search criteria structure rn_search: unsigned int flags; // status flags see MATCH macros below unsigned int ports; // port bitmask char productid; // product id char productrev;...
- Page 94 int rn_write(int handle, int regno, char *data, int datalen); Writes a string to the specified device and register. Waits for results. check device infor- This function will mation to determine that the peripheral card is connected to a master. PARAMETERS handle is an address index to device information.
- Page 95 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 96 int rn_enable_wdt(int handle, int wdttype); Enables the hardware and/or software watchdog timers on a peripheral card. The software on the periph- eral card will keep the hardware watchdog timer updated, but will hard reset if the time expires. The hardware watchdog cannot be disabled except by a hard reset on the peripheral card. The software watch- dog timer must be updated by software on the master.
- Page 97 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.

D.3.1 Status Byte Unless otherwise specified, functions returning a status byte will have the following format for each designated bit. 00 = Reserved 01 = Ready × × 10 = Busy 11 = Device not connected 0 = Device × 1 = Router 0 = No error ×... -
Page 99: Notice To Users
Specifications are based on characterization of tested sample units rather than testing over temperature and voltage of each unit. Z-World products may qualify components to operate within a range of parameters that is different from the manufacturer’s recom- mended range. - Page 100 Wolf (BL2600)
