5	RTS	6	TXD
7	DCD	8	TXCLK
9	RXCLK	10	+5VDC
11	SCA(I2C)12	SDA (I2C)

MODA (MODB) :
pin	signal	pin	signal
1	+5VDC	2	*
3	+5VDC	4	**
5	GND	6	RxD
7	GND	8	PTT
9	GND	10	TxD
*  - connected to pin 1 of P1
** - connected to pin 2 of P1

If You install custom modem instead of on board S53MV scrambler (HDLCA / MODA)
DO NOT install U11, Q3, R28, R29, R30, R31.

If You install custom modem instead of RS232 (HDLCB / MODB) do not solder U8.
