Thanks to another TN member (Matthias Jelen) the necessary RS232 cable pin
connections to connect the SR620 to TimeLab have been determined:
DB9 (PC) <-> DB25 (SR-620) 1 <-> 8; 2 <-> 3; 3 <-> 2; 4 <-> 20;
5 <-> 7; 6 <-> 6; 7 <-> 4; 8 <-> 5
Further, it turns out that there is/was a commercially made cable which is at
least available on Ebay: "Belkin F2L088 IBM AT/Modem DB9F/DB25M Cable". The
cable works like a champ and John's TimeLab picks up the counter right away.
