DIM Descriptions
Mechanical Dispenser Interface Module (MDIM) & Low Voltage Dispenser Interface
Module (LVDIM)
• The mechanical dispenser interface modules enable the TLS console to monitor either high voltage (MDIM), or
low voltage (LVDIM) volume pulses and calculate dispensed volume.
• MDIM and LVDIM terminal connections are on the front of the modules’s bracket.
Electronic Dispenser Interface Module (EDIM)
• Installs in a communication slot of TLS-350R or TLS-450/TLS-450PLUS. EDIMs are used to communicate via
RS-232 to point of sale or system controllers.
• More than one EDIM can be installed in any combination with other DIM types.
• EDIMs have one 25-pin D connector (TLS-350R), or one 9-pin D connector (TLS-450/TLS-450PLUS) outside
of the port.
• TLS-350R EDIMs only - when onboard red LED is turned On, EDIM is transmitting to external device; when
onboard green LED is turned On, external device is transmitting to EDIM.
• TLS-450 and TLS-450PLUS hardware is standard equipment.
• TLS-450 requires BIR to activate DIM.
Current Loop Dispenser Interface Module (CDIM)
• TLS-350R console - Installs in comm slots 1, 2, or 3; TLS-450 console - installs in comm slots 1, 2, or 4
(preferred); TLS-450PLUS console - installs in comm slots 1 or 2. Factory installed in TLS4 console.
• TLS-450 and TLS-450PLUS require module kit P/N 330020-665.
• Various CDIM monitoring applications include current loop, RS-232, and RS-422.
• More than one CDIM can be installed in combination with other DIM types.
• CDIMs have three RJ-45 modular connectors (TLS-350R) or 2 to 3 RJ-45 modular connectors (TLS-450/TLS-
450PLUS).
• CDIMs cannot transmit to external device.
• Connects via 4-wire cable to cable adapter box. Adapter box converts target communication format to RS-422
format for CDIM. Adapter boxes are configured with 2-wire flying leads, 25-pin D or 9-Pin D, T-cable connectors
for various applications.
• TLS-450 requires BIR to activate DIM.
LAN Dispenser Interface Module (LDIM) - TLS-350R only
• Installs in a communication port of TLS-350R to communicate with or monitor POSs, dispensers or system
controllers using RS-485 communication standard.
• An LDIM can be installed in combination with other DIM types.
• LDIMs have a 5-wire phoenix connector.
• Red and green LEDs are on this board. When red LED is turned On, LDIM is transmitting to external device;
when green LED is turned On, external device is transmitting to LDIM.
• Can be used in 4-wire or 2-wire, RS-485 and RS-422 applications.
- DIP switch default in OPEN position, loopback jumper on LED side for RUN mode
- R1 - 331076-001 - RS-485 two wire
