Page 2: Section 1 - Description
DESCRIPTION The BT-1 BERT tester is a digital RS-232 test set for modems, DSUs, line drivers, multiplexers, terminals, printers, etc. Test functions include: Bit Error, Block Error and Mirrored Bits tests Polling tests (proprietary, DNP3 and Modbus) ... -

This indicates the screen choices are more than 16 characters wide. Use the right or left arrow keys to view the extended screen. The BT-1 can often be used to perform a test right out of the box. The defaults are as follows:... -

STOP Stops the test... - Page 6 4.3 Getting Started Most functions of the BT-1 are done with just a few keys. The SET PARM is used to set the speed, parity, word length, and test duration. The SET TEST key selects the test to be performed. The ARROW keys get you around the screen.
- Page 7 The stop on error will stop a Bert test when the BT-1 sees a receive data error. The stop on error function is an excellent tool to use along with a data line monitor to trap data errors when debugging equipment.
- Page 8 The QBF message used in the DCB BT-1 is most likely unique to the BT-1. QBF# “Quick brown fox” with a block number at the end, where the block number ranges from 000 to 999, then starts again at block number 000.
- Page 9 Poll Tests DCB HOST The polling tests require one BT-1 to be set as the host unit. The setup screen is a double wide screen, where the 2 halves of the setup screen are accessed using the right and left arrow keys(> and <).
- Page 10 In the above example, the POLxx refers to one of the drop numbers, which can range from 01 to 16. DCB DROP Up to 16 drop units can be set up for polling. Each drop gets a separate number, ranging from 01 to 16.
- Page 11 9600, etc., is the async speed of the polling test, if set to ASy. The screen shows “” if set to xSy. xxxm Sets the time in milliseconds for the drop to delay the response to the host poll. Values range from 0 to 300ms in 25ms increments. Test results are as follows: Screen POLxx RESP...
- Page 12 DNP3 host mode. The asterisk (*) indicates a poll response. The DATA value will increment by one each time if the response is from a BT-1, starting at 00000, then 00001, 00002, 00003, etc. DNP DROP Up to 16 drop units can be set up for polling. Each drop gets a separate reference number, ranging from 01 to 16.
- Page 13 Host, the register value increments 1 after each poll. At the Host BT-1, the received values will be 00000, 00001, 00002, etc. ADR is the drop number and DNP3 address. The default values for the drops are 01=10100, 02=10200, and so on up to 16=11600.
- Page 14 actual drop holding register is one less than the number shown in the last four digits of the "R:4xxxx" setting. For the default "R:40001", holding register 0000 is requested. screen screen Poll: MB HOST-01 TMO=2.0s R:40001 9600 1.0s> <ADR01=101 HOSTXX selects the number of remotes to poll, ranging from 01 to 16. 8N2 sets the character length, parity and stop bits.
- Page 15 In the above example, the PLxx refers to one of the drop numbers, which can range from 01 to 16. The DATA field will increments (if the response is from a BT-1) starting 00000, then 00001, 00002, 00003, etc.
- Page 16 (high/low) signal levels. The test are as follows: RTS/CTS DLY measures the time from the BT-1 asserting RTS (pin 4) until CTS (pin 5) is returned from the attached equipment. ECHO 1 CHAR measures the time it takes for a single character to be sent from the BT-1 and echoed back to it.
- Page 17 At 9600, the BT-1 gives a result of 9597 or 9606. At 1200 bps, the resolution is .14 bps, and at 56000 bps the resolution is 314 bps.
- Page 18 MB RTU is a monitor function. It shows the Modbus addresses that are being polled. RTS+ toggles the RTS lead (pin 4) from an off state to an on state for a period ranging from 0.5 milliseconds to 30 milliseconds. It does this once, or 1, 2 , 5 or 10 times per second.

1200, then the clock rate on pin 24 is 16 times 1200, or 19,200 bps. Accessories The following accessories are included with each BT-1 test set. They provide the versatility required for connection in DNP3 and Modbus polling or monitoring applications as well as more conventional RS232 BERT tests. - Page 20 5.2.2 Adapters DNP Rx, DCB P/N: 9802084 RJ45 DB-25S DNP 25, DCB P/N: 9802083 RJ45 DB-25P DNP 9, DCB P/N: 9802085 RJ45 DE-9P 5.2.3 Applications 9 pin Connection as Host or Drop 25 pin ribbon Black or Red 9 pin ribbon...
