Simplified Option Interface Unit (Pious); External Page Interface Unit (Pepu) - Toshiba Strata DK14 General Description Manual

Universal Slot PCBs
Option Interface PCBs
DK424 – the PIOU provides two-relay contact pairs. One of the contact pairs can be set for
control of a customer-provided door lock or control of a MOH source. The other relay pair can
be configured to mute BGM while the page feature is being activated or for the Night Relay
function.

Simplified Option Interface Unit (PIOUS)

The PIOUS has most of the PIOU's features, including SMDR output and the TTY output port
interface and IMDU. It also provides flexible relay contacts and an Unamplified Page output. It
does not provide Amplified or Zone Paging.
Remote Maintenance Subassembly (IMDU)
The IMDU is an optional modem that connects to a PIOU or PIOUS to link the system to off-site
programming and maintenance equipment, such as a DKAdmin PC. The IMDU has an internal
maintenance channel and does not require a dedicated CO line or station port. Data transmission
speed can be set at 300 or 1200 bps full duplex.

1. Amplified page output (single zone, 3 watts, 8 ohms) on the PIOU and PEPU is not available on the DK40i.
2. These functions are standard (built-in) to the DK40i Base KSU.

External Page Interface Unit (PEPU)

The PEPU is a reduced version of the PIOU and PIOUS, providing most of the Paging and Relay
Contact options offered by these other optional PCBs.
