HAYES-TYPE SMART MODEM
(FUNCTIONS LIKE A DCE)
PDIU-DS
(CONFIGURED IN THE "CONNECT TO MODEM"
MODE, P1 ~ P9 = B-C, SO IT FUNCTIONS LIKE A DTE)
NOTES:
1. Modem receives data on pin 2 (TD) and transmits data on pin 3 (RD).
2. The PDIU-DS must be in the connect to modem mode (P1 ~ P9 strapped B-C) so that it transmits
data on pin 2 (TD) and receives data on pin 3 (RD).
