Software Selectable EIA-232/422/485:  Even though most POS peripherals are based on EIA-232, some equipment such as weigh scales require EIA-422 for longer distances (warehouse, loading dock, etc). A software selectable interface is preferred over products that use DIP switch selection. Software selection prevents accidental changes due to mechanical tampering in the field.

15Kv ESD Protection:  Perle 15Kv surge protection also reduces the effects of static.  This is especially important for carpeted retail locations where disruptions caused by static discharge is a constant challenge.

Secure serial data transmission via SSH and SSL: Many credit card companies are now having their merchants enforce rules in the way credit card information is processed and transmitted across their network. These enforcement programs, such as Visa’s CISP, require that information from devices such as credit card readers be encrypted using SSH technology. The IOLAN SDS can encrypt sensitive and confidential serial data across an IP network.

Power POS peripherals over serial: The IOLAN SDS has the ability to power low power parasitic devices over the serial connection. This eliminates the need to install separate power for the peripheral, saving costs and eliminating a possible point of failure.

The bottom line: By providing a flexible, secure and reliable serial connectivity solution, IOLAN SDS device servers are ideal for connecting serial POS devices across an IP network for retail applications.
