DS2149DK/DS21349DK T1/J1 Line Interface Unit Design Kit
BASIC CONFIGURATION
The following example configurations provide a quick start to using the DS2149DK/DS21349DK, although there are
many ways they can be configured. To set up other configurations, refer to the DS2149/DS21349 data sheets in
addition to this data sheet.
T1 Hardware Mode—External Remote Loopback
1) On the system connector, jumper TPOS to RPOS, TNEG to RNEG, RCLK_CON to TCLK, and
RELAY_CONTROL to GND.
2) JP8, jumper RCLK to CON.
3) Remove JP5, TCLK_EN.
4) Jumper JP6 MCLK_EN.
5) JP9, JASEL, jumper to GND.
6) JP7, TAIS, jumper to GND.
7) JP10, MODE0, jumper to GND.
8) Jumper JP3, MODE1_EN.
9) Jumper JP4, RLS_EN.
10) Jumper JP2, LLB_EN.
11) On SW1, switch MODE1 to MODE1_LO.
12) On SW1, switch L0 to L0_HI.
13) On SW1, switch L1 to L1_HI.
14) On SW1, switch L2 to L2_LO.
15) On SW1, switch L3 to L3_LO.
16) On SW1, switch RLB to RLB_LO.
17) On SW1, switch LLB to LLB_LO.
18) Place appropriate device in socket.
19) Select the power 5V or 3V depending on which device you use.
20) Connect J2 and J3 to test equipment
Device should be in external remote loopback.
T1 Software Mode—External Remote Loopback
1) On the system connector, jumper TPOS to RPOS, TNEG to RNEG, RCLK_CON to TCLK, and
RELAY_CONTROL to GND.
2) JP8, jumper RCLK to CON.
3) Remove JP5, TCLK_EN.
4) Jumper JP6 MCLK_EN.
5) JP9, JASEL, jumper to GND.
6) JP7, TAIS, jumper to GND.
7) JP10, MODE0, jumper to GND.
8) Jumper JP3, MODE1_EN.
9) Jumper JP4, RLS_EN.
10) Jumper JP2, LLB_EN.
11) On SW1, switch MODE1 to MODE1_HI.
12) Place appropriate device in socket.
13) Select the power 5V or 3V depending on which device you use.
14) Connect J2 and J3 to test equipment.
15) Load the DemoView software.
16) Select RegView.
17) Load the DS2149.DEF file.
18) Write CR1 to 0x03.
19) Write CR2 to 0x00.
20) Write CR3 to 0x00.
21) Write CR4 to 0x00.
Device should be in external remote loopback.
