D. RS422 Interface
The interface between the DLRB and the DLS is made of a RS422 bi-directional serial link.
(1) Information exchanged on the serial line
(a) From the DLRB to the DLS
1 During normal operational mode
_ The content of the text which is displayed on the LCD screen.
2 During power-up mode of DLS
_ Information devoted to initialization of the LCD screen.
(b) From the DLS to the DLRB
1 During normal operational mode
_ NEXT, PREV, SEL CTL keys signals and DLS BITE status which are treated by the DLRB.

2_ During power-up mode
The resulting BITE status of the test which is analysed by the
DLRB.
E. RS-232 Interface Part of the connector is reserved for Portable Test Equipment (PTE) use
during workshop maintenance operations. BITE results are stored in a
non-volatile memory (NVM).
This memory reserved for recording failures is divided into 4 zones. Zone
1 stores internal and external failures detected during the last or
current flight leg.
Zone 2 stores internal failures detected on the ground.
These two zones can only be read by the CFDIU.
Zones 3 and 4 provide permanent storage of in-depth data concerning the
failures (information on the internal part of the data loader).
These two zones can only be read by the PTE. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM 指示/记录系统 5(124)
