The DT-4315 is a dual port terminal (compatible with the DT-4314) with many new features including: o DEC VT-100 terminal emulation o includes Desk-Top ultilities o uses a PC-type keyboard o utilizes RJ45 serial port connectors o 14" screen *** NACS MACHINE TYPES AND FEATURE NUMBERS *** 4315 *** AVAILABLE DOCUMENTATION *** Refer to GENERAL-BASIC FOUR-DOCUMENTATION FIB number 4 for available documentation. *** AVAILABLE TRAINING *** N/A *** SPECIAL TOOLS *** N/A *** SPECIAL ADMINISTRATIVE PROCEDURES *** N/A ORIGINATOR: Norm Jones VIDEO TERMINAL-BASIC FOUR-4315,DT-4315,DT4315-------FIB001 Pg001 FIB 00002 03/07/91 *** Tilt/Swivel Base is Optional *** Preliminary Field Bulletin Product : Terminals Author : Anthony J. Kaczoroski DT-4315 Issue : Optional Tilt/Swivel Base Assembly Type : Informational The Optional Tilt/Swivel Base is an OPTIONAL item, it does not automatically come with the terminal and must be ordered separately (KG020Z, 400781-003). In the first shipments of the DT-4315 terminals the installation instructions were inadvertently included in with the terminals. This situation has been correcte and all future shipments of the DT-4315 terminals will not include these installation instructions. ORIGINATOR: Tony Kaczoroski VIDEO TERMINAL-BASIC FOUR-4315,DT-4315,DT4315-------FIB002 Pg001 FIB 00003 04/09/91 *** Hardware flow control [ WPSF 701 A1 ] *** Product : Terminals Author : Anthony J. Kaczoroski DT-4315 Issue : Hardware Flow Control Type : Informational The hardware flow control for the DT-4315 terminal is slightly different from that of the DT-4314 terminal. The DT-4314 supports the full set of flow control lines, which includes RTS, CTS, DSR, and DTR. The DT-4315 in using the RJ45 connector only supports DTR and CTS. This is not an issue when connecting the DT-4315 to any of the MAI systems, (GPx, MPx, or SPx), but it may present a problem when trying to connect the DT-4315 to other system types that monitor Pin 4 RTS instead of Pin 20 DTR when using Hardware Flow Control. In cases like this there are 3 possible solutions: 1- Configure the system port for Xon/Xoff Flow control instead of Hardware Flow Control. 2- If using the DB25 to RJ45 adapter cable 916794-001, you can modify it by moving Pin 20 (DTR) to Pin 4 (RTS) on the DB25 side. 3- Modify the system data cable at the system end by jumpering Pin 4 (RTS) and Pin 20 (DTR) together.

KACZOROSKI VIDEO TERMINAL-BASIC FOUR-4315,DT-4315,DT4315-------FIB003 Pg001 FIB 00004 05/07/91 *** Unable to save PF keys - perform MASTER RESET from set-up menu *** SYMPTOM: Unable to save PF keys as 'permanent', PF key lost after cycling power PROBLEM DETERMINATION: If a message "HOST CHANGED FUNCTION KEYS. RESTORE SAVED VALUES [n]/y" appears when Programmable Function Keys is selected from the MAIN Setup menu, there may be modes set which will not allow PF kets to be saved. FIX: Select TERMINAL MANAGEMENT from the MAIN Setup menu, then select MASTER RESET. This will reset EVERYTHING including PF keys, follow the instructions in section 7 of the 4315 VDT User Guide to set the PF keys as . desired. NOTE: This condition can be set in the MAIN LOGIC PCBA, could be this way from stock requiring a MASTER RESET to clear. It is probably a good idea to perform a MASTER RESET after replacing a MAIN LOGIC PCBA. Other functions may not work correctly due to host escape sequences or noise into the port, a MASTER RESET should clear any inadvertent modes set in NVRAM.

Cause: Two problems have been found with the Rev B firmware. One problem does . not affect customers. The second problem is that data may be lost when slave printing to a PT-4229. The 4229 is the only printer this problem has been seen on, but all printers have not been verified. A system running with low usage is more likely to see the problem because data is being sent to the terminal more rapidly. Because of these problems there will be a Revision C which is scheduled to be released very early in November. Caution: Some new DT-4315s have been shipped with Revision B, so at this time avoid attaching 4229s to these terminals.

Cleaning and simple repair should be attempted on ALL keyboards at the field level. This covers both "switch-type" keyboards, as well as "membrane-type". Keyboards should be repaired on-site, and where this is not possible, brough t back to the office or stocking location and cleaned/repaired there. In general, the keyboards can be repaired by disassembling them, blowing-out or brushing off dust and debris, cleaning the PCBA using a foaming-type window cleaner (like aerosol Windex), brightening contact points by rubbing them with an eraser (Pink Pearl), and replacing any worn-out springs or pads Even the newer-style membrane keyboards (such as the DT4315, PSx30, etc.) usually fail because of dust or liquid contamination between the membrane layers preventing a key from making contact. Disassembling these keyboards i s equally easy and the membranes can be cleaned by wiping them with a soft cloth dampened with window cleaner. 2. Several hundred keyboard repair kits were distributed throughout the field in the past. Replacement parts for these kits can be ordered through Tustin, part numbers are as follows: Parts for 7270, 4309, and 4312 keyboards. Spring, Spacebar YY013799 Spring, Print Key, Clear, Escape YY012913 Spring, All Others YY012914 Pad (foam/foil for each key) YY006594 Screws (hold PCBA to Keyboard) YY019809 3. After cleaning the keyboard and attempting simple repair, if the keyboard is still not working properly, return it to Tustin using the normal return process. 4. MM810041 (Grey 4312 keyboard) and MM810036 (Putty 4312 keyboard) are alternates for each other and should be treated as such. If you need the opposite color, take the time to switch the keycaps and enclosure rather than ordering another keyboard. (Estimated time of about 10 minutes to switch everything). 5. Effective February 1, 1991, the field will not be able to Code A the 4309 and 4312 keyboards from Tustin (P/N MM783020, MM810036, MM810041).

The protocol problem with the BFIS->ISP and BFIS->BFIS modes has been fixed. This problem happened when the code preceding the CRC character in the BFIS protocol was followed by an checksum value. The occurrence is no w handled correctly. 2. The Packet Panic that occurs when a bypass print is performed after a VT reset, has been fixed. 3. The Packet Panic that occurs when several VT Resets have been performed, has been fixed. 4. The Packet Panic that occurs when many B's are sent, has been fixed. . This happens on 13XX quite often. NOTE: This Revision change available with Market Code KE192AA.

Without a password the terminal will not operate on a system and the set-up menu is inaccessible. FIX: 1. Power terminal off and remove cover. 2. At IC location U6, connect a jumper from pin 5 to ground. 3. Power on terminal, enter set-up menu and disable password security. 4. Power off terminal, remove jumper, and reassemble terminal.

Solution: You must modify the terminal setup, In Terminal Management select Vitual Terminal Options, Select Configure Selected VT, select VT100 parameters, select option Bold attribute and change the option from Half Intensity to Compatible and save the change. Note : The option for Bold Attributes are not found on DT 4315 & 4315A terminals that are on REV A. You must be on REV C or above to set this option.
