CPU DV 1000 lt L D a Pa Phone jack style Universal 15 pin Std phone jack connector RJ12 D sub connector NOTE The DV 1000 uses K sequence protocol to communicate to the PLC Some T1435 CPUs could reliably connect to only one device at a time using K sequence protocol K sequence protocol is available on all ports on DL105 DL205 DL405 and DL350 CPUs 8 Installation Guide The first method the preferred method uses a special shielded cable with a modular phone jack style connector on one end and a 15 pin D shell connector on the other The connectors plug directly into the DV 1000 and CPU port The second method uses a non shielded cable and an adapter plug from the cable kit The cable same as DL105 DL205 DL350 DL450 cable has a modular phone jack style connector at both ends so either end will connect to the DV 1000 The other end connects to an adapter to go from a 6 conductor modular to a 15 conductor D shell to connect to the CPU port Custom Cables In some applications the length of the standard PLCDirect cable may not be quite long enough You may make your own cable but observe the following guidelines e Use a shielded type cable Be sure to connect its shield at both ends to the appropriate connector pins e Do not exceed 15 feet in length NOTE The standard cables are approximately 6 feet long If you have determined the need for a cable longer than 6 feet you may use a slightly longer one

DV 1000 display at the same time The two V memory data blocks certainly coexist but the DV 1000 gives display priority to the text data Each text character s data masks the corresponding numerical digit if the text s ASCII code is 20 hex or greater It is convenient to think of the text 00000000 output as a control mask for numeric 0000000 output Refer to the figure to the Numeric Output right If the numeric data block in 000000 V memory is all zeros the matching 0000 numeric output is also zeros as shown Now suppose the text data is a also all zeros null characters except for four random locations as shown Text data ASCII codes 41 A through 44 hex produces the letters B A B C and D Now we come to the Text Output actual display output It is a combination of the numeric and text E D output characters The DV 1000 uses a simple principle to determine what to display in each character location 00A00000 Any text character which has an 000B000 f ASCII code equal to 20 hex or dlololclolo Actual Display Output greater masks blocks the 000D numeric digit in the same display position That s it This works ona 3210 character by character basis 32150 One of the first things you may want to do in your setup program is fully mask all numerical output so we begin with a blank display unless you use ACON boxes to fill the entire display This is analogous to starting with a clean slate
