NetPIT and PIT Devices

Support for Protocol Interface Translators
Honeywell supports Protocol Interface Translators (PITs) and a networked Protocol Interface
Translator (NetPIT), for attaching many serial devices to a Multi-Media unit.
Fig. 8–11. Cash Registers, Connected to a Honeywell PIT.
A NetPIT device provides communications for up to 16 POS devices from one serial port. NetPIT
supports applications by Retalix (RetPIT), Micros (MicPIT) and AtmPIT. A PIT can provide
communications for one device (AVBPIT1) or up to four devices (AVBPIT4POS); see figure 8–11.
When assigned to a port on a Multi-Media unit, the configuration values of the serial interface are
shown. See figure 8–12.

When expanded, a NetPIT device shows 16 virtual ports, labeled "A" to "P"; see figure 8–13. A PIT
device (AVBPIT4POS) shows 4 virtual ports, labeled "A" to "D". When a device is assigned to a
virtual port, the settings of that device are shown on the Serial Devices tab. Each virtual port can
be configured independently for speed, data format, and protocol. For the details of the
configuration for these devices, see their documentation.
