Advanced GSM Start-up and Service
Advanced GSM
The Advanced GSM replaces a Standard GSM. It is configured to work with the CRIND
FlexPay EPP with Gilbarco CRIND (Generic and MOC), without any controller (POS)
changes, in TDES mode.
The POS/Forecourt software communicates with the Advanced GSM through standard PC
“COM Port” operations.
If an Advanced GSM fails, the system will recover automatically upon power-up when a
replacement Advanced GSM is connected.
The Advanced GSM is required for debit to work in SDES/TDES mode.
