AuditLok XLV Communication

External Communication Rules

1. Up to 15 R-units (any combination of V1R and V2R), may be added to one C-unit.
2. Up to 4 displays (EPR) may be connected to the system.
3. All R-units, including EPRs (after the first display), must be added using the Add Device procedure.
4. As soon as an R-unit is added, that R-unit is available on the Device Menu list to configure and use.
5. Once an R-unit is added, it will no longer respond to an Add Device request (until it receives a Remove Device command).
6. One display at Display Address 00 will communicate with the CPU. Only one display may be at Display 00. Any additional displays in the system are treated like R-units and must be added before they will communicate properly.
7. The rated maximum data bus length is 300 feet. Actual maximum length depends on wire quality, routing, and the presence of electronic noise in the environment.
8. S/N SP2008032034 and later (or upgraded older safes): Use shielded twisted pair for all data bus connections. The data bus must always be properly terminated to protect against electronic noise interference. A termination plug must be plugged into the DATA END port on the last R-unit on the data bus (V1R, V2R or EPR).

C and R Connection

D8C Internal Communication Rules

1. C-unit internal communication (CPU to lock and vend boards) is established independently from any external (R-unit) communication.
2. If the D8C has a built-in display, it is operated from a CPU port separate from other internal devices. A built-in display is always the primary (Address 00) display.
3. If the primary (Address 00) display is external it is effectively treated as an R-unit except that it may be connected to the data bus even during a Device Search.
4. All R-units (except the primary display) must be disconnected when performing a Device Search.
5. The Device Search procedure must be performed in order to establish communication between the CPU and internal devices (lock boards, vend board, UIB).
6. The internal data bus must be terminated to protect against electrical noise interference.
Internal Data Bus Termination: Set the D8C outer door lock board SW1 Segment 8 set to ON to terminate the internal data bus. If the D8C has a built-in display, a jumper (part 15187001) should be installed at SW1 on the back of the display board.

V1C/V2C Internal Communication Rules

1. Internal communication (CPU to UIB and Lock Boards) is established independently from any external (R-unit) communication using the Device Search procedure.
2. The primary display is at Display Address 00.
3. All R-units (except the primary display) must be disconnected when performing a Device Search.
4. The internal data bus consists of the connection from Daughter Board (CPU Assembly) J9 to the first UIB J1; from first UIB J2 to J1 on the next board on the bus and so on depending on the number of boards present. The last Lock Board on the bus will have J2 open.
5. The internal data bus must be terminated to protect against electrical noise interference. Terminate the data bus by setting SW1 Segment 8 to ON on the last Lock Board on the bus.
6. If the safe has any model of JCM validators (BNF, WBA, etc.): set SW2 Segment 1 to ON on each UIB. If the safe has any model of CashCode or Mars validator: set SW2 Segment 1 to OFF on each UIB.

V1R/V2R Internal Communication Rules

1. Internal communication (UIB and Lock Boards) is established independently from any external (R-unit) communication using the Device Sync procedure.
2. R-unit electronics must be isolated from all external data bus connections while performing a Device Sync.
3. The internal data bus consists of the connection from the first UIB J2 to J1 on the next board on the bus; J2 on the second board to J1 on the third board (if present); then J2 on the third board to J1 on the fourth board (if present). J2 will be open on the last Lock Board on the bus.
4. The internal data bus must be terminated to protect against electrical noise interference. Terminate the data bus by setting SW1 Segment 8 to ON on the last Lock Board on the bus.
5. If the safe has any model of JCM validators (BNF, WBA, etc.) set SW2 Segment 1 to ON on each UIB. If the safe has any model of CashCode or Mars validator set SW2 Segment 1 to OFF on each UIB.

Max Vend Internal Communication Rules

1. Internal CPU to UIB and Lock Board communication is established independently from any external (R-unit) communication using the Device Search procedure.
2. Internal CPU to Hopper Board communication is independent of all other communication. Communication support for the Hopper Board is “hard coded” into the CPU software. The Hopper Board is not subject to the Device Search.
3. The primary EPR display is at Display Address 00.
4. All R-units (except the primary display) must be disconnected when performing a Device Search.
5. The internal data bus consists of the connection from CPU Assembly (bottom board) J9 to the UIB J1; then from UIB J2 to J1 on the lock board. A special DB9/RJ45 cable connects the Hopper Board to CPU Assembly (top board) J6.
6. The internal data bus must be terminated to protect against electrical noise interference. Set the lock board SW1 Segment 8 set to ON to terminate the internal data bus.
